How to invest in the profitability or quality factor

Ever been passed over for promotion by some smooth-talking stuffed shirt? Then take heart from the profitability factor. Also known as the quality factor, this is a real-world example of the triumph of the best over the rest.

The profitability/quality factor reveals that companies that make the best use of their capital outperform their less efficient brethren over the long-term.

In fact, the most profitable companies can bring home a return premium that has hitherto beaten the market by up to 4% a year.

The trick is to invest in the companies that are rippling with the signs of financial prowess most likely to predict profitability in the future.

Like a Moneyball chief scout or an international Top Trumps player, you need to know which stats matter most…

…or you could just pick an Exchange Traded Fund (ETF) with Quality in its name.

Quality over quantity

There are only three quality factor ETFs currently available to UK investors. Choosing one shouldn’t take long, right?

The snag is that financial engineers have more definitions of quality than the Eskimos have words for snow.

True, every kind of return premium can be formulated in different ways

But quality comes in so many flavours that you just know some must be watered down.

How do you choose the right version of quality? Is there a right version? Which has performed best historically? Does it even matter?

A trip down quality street

First of all, it’s important to understand that quality can be defined by a single measure, or by a cocktail of stats as drawn from a company’s annual report.

Here’s a snapshot of the yardsticks used by different industry practitioners:

  • Gross profits / assets – This is gross profitability as defined by Professor Novy-Marx and widely considered to be the champagne of quality factors.
  • ROE, debt to equity and earnings variability – Used by the MSCI Quality Indices.
  • Stability of earnings and dividends over the last 10 years – The S&P formula.
  • Gross profits / assets and gross profit margins plus free cash flow / assets – The preference of US fund house AQR.
  • Net income, operating cash flow, return on assets, stability of earnings, leverage, liquidity equity issuance, gross margins and asset turnover – The Piotroski F-Score financial health test.

Novy-Marx’s work caused a stir because his gross profitability metric trounced the market by 4% a year between 1963 and 2011. As a single quality metric it’s tough to beat and I’d want it or a close proxy in any quality fund I bought into.

However even Novy-Marx thinks that the best quality metric will be a blend of measures. For example, cash flow / assets is unpolluted by some of the accounting inconsistencies that can interfere with the gross profitability signal.

The question then is do the available ETFs offer us the finest quality cuts, or are they slipping in some horse meat?

(Or – worse – horse output!)

Quality ETFs

Each ETF has its own quality mix

The three ETFs I mentioned earlier all track developed world equities, using a blended metric to tilt their holdings towards the quality end of the spectrum.

The higher a stock scores on the fund’s quality scale, the greater its presence, subject to any applicable cap.

Note: These ETFs are so new that it’s not even worth considering their track record – they just haven’t been around long enough for their track record to be relevant.

ETF OCF (%)1 Ticker Quality metrics
iShares MSCI World Quality Factor 0.3 IWQU High ROE, low leverage, stable earnings growth
db X-trackers Equity Quality Factor ETF 0.25 XDEQ High Return On Investment Capital (ROIC), low accruals
Lyxor ETF SG Global Quality Income 0.45 SGQL High Piotroski F Score, strong balance sheet, high dividend yield

Source: ETF suppliers

Unfortunately I’m not in love with any of these ETFs.

iShares MSCI World Quality Factor ETF

Let’s start with the iShares offering.

Gross profitability appears to be the most successful of the quality metrics, but the iShares ETF uses ROE instead. Its weakness is that it focuses on net profit.

Gross profitability highlights companies that are investing in future revenues by devoting resources to R&D and advertising. But these beneficial activities subtract from a firm’s net profit and make it look less profitable in ROE terms.

The paper Global Return Premiums on Earnings Quality, Value and Size analysed a suite of quality factors (not including gross profitability) and placed them in the following order of performance:

  1. Cash flow to assets
  2. Accruals
  3. ROE
  4. Low leverage

Cashflow was by far the best metric, with little separating the other three.

A second paper – this time by Pimco – criticises the other two metrics used by the iShares ETF: low leverage and stability of earnings growth.

Here’s what the paper’s authors have to say:

There is little agreement that buying stocks of companies with low debt generates alpha. In fact, according to the evidence available in the academic studies of Bhandari (1988) and Fama and French (1992), low-leverage firms tend to underperform.

We are not aware of any empirical link between earnings volatility and expected returns. The only related papers, to our knowledge, are Haugen and Baker (1996) and Huang (2009). The former found no significant relationship between returns and volatility of earnings yields. Huang found the firms with stable cash flows tend to outperform.

Finally, the annual return of MSCI’s quality metrics (as tracked by the ETF) trailed in a lowly fourth place between 1985 and 2012, according to the paper Defining Quality by the asset manager Northern Trust.

It ranked the annual returns of various quality formulas as follows:

  • Piotroski F-Score: 8.4%
  • DFA’s metric2: 6.3%
  • ROE: 5.5%
  • MSCI 4.9%

Overall then, I’m unconvinced that the iShares ETF is using a particularly effective form of quality.

What’s more, iShares optimisation rules mean that it can hold stocks that are not in the index if it thinks the substitutes will give a similar performance.

The whole point of passive investing is to provide a set of rules that remove subjective judgements – rather than to provide enough get out clauses that the fund manager can effectively do what it likes.

db X-trackers Equity Quality Factor ETF

The Deutsche Bank ETF whips up its quality formula from Return On Invested Capital (ROIC) and accruals.

Accruals is okay as a quality factor but hardly a barnstormer according to the Global Premiums paper referenced above.

Moreover, accruals can be calculated in many different ways, which adds an extra level of complexity when you’re trying to work out what exactly you’re getting from the ETF.

ROIC does marginally better than ROE in the return stakes according to Pimco, but it’s still a net income metric that lacks the potential punch of gross profitability.

Once again, I’m left with the feeling that the quality on offer could be better.

And I’ve got even bigger problems with the index the ETF tracks – it’s owned by Deutsche Bank who also own this ETF.

Deutsche Bank can amend its index rules as it sees fit. That lack of independence makes me uncomfortable with a product that is meant to operate according to a strict set of rules. Rules don’t mean much if you can change them at a stroke.

Lyxor ETF SG Global Quality Income

Multi-factor products are probably the future – a single fund that enables you to combine the profitability, value, momentum and market factors all in one.

The Lyxor product feels like an early stab at this. It combines aspects of value (a high dividend yield) with quality (the Piotroski F-Score) and ends up with a defensive tilt that resembles a low volatility ETF.

As we saw earlier, the F-Score has proved pretty successful in the past at capturing the quality premium.

Big tick!

However Lyxor’s defensive recipe then concentrates the ETF in 25 to 75 companies (versus 298 in the iShares ETF) with a 32% allocation to utilities alone, according to its fact sheet.

That’s effectively a bet on a particular sector that we have no reason to believe will outperform. There is no evidence to suggest that any sector delivers excess returns over time, and investors are not rewarded for taking that risk.

So while the asset allocation of this ETF is significantly different from the other two, the lack of diversification makes me wary.

The index used is again the property of its parent company, Societe Generale, with the wheel clamp on independence that implies.

Finally, it’s a synthetic ETF. That doesn’t overly bother me but it does bother many others.

Quality streak

All three ETFs contain an element of quality but not the high-grade stuff I’m looking for.

If they combined gross profitability with cash flow then I’d feel much happier about signing up. As it stands I’d rather wait and see if anything better comes along.

It must be said that different definitions of any risk factor will outperform at different times. For all anyone knows, the quality metrics of these ETFs could hit an amazing streak in the years to come.

For example, ROE weathered the 2000-2002 and 2008 bear markets very well. Low leverage was a star in the late 1990s but fell from the sky after the 2000 tech bubble burst.

But all that is a matter for the gods. Right now, I’m content to watch these first-mover products build up their track record while I wait for other market players to improve upon them with the next generation.

Think of it as like buying a high-quality third-generation Apple wonder-gadget, rather than a first iteration device held together with innovative sellotape.

Weekend reading: Time to expose the closet tracker funds

Weekend reading

Good reads from around the Web.

Moves are afoot to compel active und managers to reveal their ‘active share’ – an indication of the degree to which their portfolios differ from the market.

The greatest benefit would be to highlight closet tracker funds. These are active funds that charge high fees but can only ever deliver less than average returns because they essentially track the market.

Getting market returns while paying high costs is a guaranteed bad deal. A big benefit of market-tracking passive investing is that low charges leave you with more of your own money to compound over time.

The FT says [search result] that some fund managers are already planning to highlight their active share to investors:

Threadneedle Investments, which manages £92bn of assets, said it plans to begin disclosing the “active share” percentage on its fund factsheets and believes others should do the same.

“It’s something would have real merit and we would support seeing developed into an industry standard and normal market practice,” said Iain Richards, Threadneedle’s head of corporate governance and responsible investment.

“There is a valid concern about closet index tracking funds that charge active fees. It’s clear investors need better transparency around this and more consistent disclosure of a fund’s active share measure is one part of the solutions.”

Obviously this could be pressed into service as a marketing ploy for funds that are going through a good spell as much as any noble act of transparency. But it’s still a development I’d welcome.

Some people like to invest in active funds. They need to better understand what they’re buying.

More active might mean better returns…

For one thing, research suggests – at least to some onlookers – that high active share may be a signal that a fund manager has genuine market-beating potential.

I’ve not been convinced by what I’ve read, although I’d stress I’ve not rigorously investigated it all. I’ve simply come across various summaries over the years.

One big hesitancy I’ve had is that it seems obvious that a set of market-beating active funds is going to comprise of mainly funds that don’t look like the index.

If they held the same shares as the index, then by definition they wouldn’t have beaten it!

Yet presumably many of the funds that lose the most also look very different from the index, for exactly the same reason. (This is what gave rise to the practice of closet index tracking in the first place – better for a highly paid fund manager to be safe than sorry).

Perhaps this has all been taken into account in the research into active share. I need to set aside a Sunday to find out.

…but what do you care?

People tend to find what they’re looking for in this sort of thing.

For instance, I like and often link to the writings of the value investing team at Schroders, which has a blog called The Value Perspective.

This week one of their number found comfort in academic research that suggested that as well as a high active share, the best performing fund managers rarely trade:

The great majority of the outperformance of the universe of funds considered by Cremers and Pareek comes from the ‘high active share/long holding period’ group.

In other words, while not specifically on the subject of value, their paper appears to show that being prepared to be contrarian and patient – as value investors often are – plays a big part in achieving strong investment performance.

I sent a link to the article to occasional Monevator contributor The Analyst, as I know he likes to buy and hold for the very long-term.

Yet barely an hour later, I came across other research saying that actually, very high turnover active funds do better.

So I sent him that along as well.

With a shrug.

And that’s another reason to go passive – opting out of all this debate with a smile of ‘who cares’!

A landlord is someone who borrows money on your behalf

Tenant, landlord, homebuyer, banker — it’s all about the money.

I have explained before how a mortgage is money rented from a bank.

When you buy your first property with a mortgage, you don’t leave the renting classes behind – you simply do your business at the more respectable end of the High Street, and rent the money needed to buy the house from Natwest or Nationwide.

Instead of giving brown envelopes stuffed with tenners to a bloke called Trevor every Thursday for the honor of living in his dive in New Cross (in spirit, I appreciate we all use bank transfers nowadays), as a newly indebted homeowner you pay ‘money rent’ every month to the bank on the lump sum it lent you to buy your home.

It’s a different way of thinking about home buying and mortgages. It doesn’t mean in itself that renting or buying is better or worse.

By the same token, this article is also not about whether you should own a home or not (or whether prices will go up or down or whether the younger generation is shafted or whether the market will crash next Tuesday or any of the usual).

It’s a thought experiment.

Let’s imagine we’re dressed in white togas eating grapes like Greek philosophers, and have ponder.

A house? For me? How kind!

So, a mortgage is money rented from a bank. Sort of.

But what about when you rent a property from a landlord?

Is that just, well, renting a property?

Of course.

But there is another way of looking at what’s going on, which adds another financial jui jitsu move to your mental arsenal.

Instead of thinking of your landlord as someone who owns the house or flat they rent to you, you might think of your landlord as someone who borrows £250,000 or £500,000 or whatever to buy the property on your behalf.

He or she borrows the money, and as a result you don’t need to do so.

You pay him rent for the privilege of him borrowing this money. The cost is usually marked up for his trouble, so your rent is higher than if you’d rented the money from the bank yourself.

In addition, your decision to rent hands the option to make money from rises in the property’s price to your landlord.

Then again, you’re also insulated from the risk of falling house prices.

The interesting thing about landlords and mortgages

This is in fact very close to what happens in practice.

Let’s say you’re renting 29 Acacia Avenue from your lovely landlord, a Mr E. Wimp Esq.

You pay him £1,000 a month to rent his house, and when you see him in the street you tug your forelock (whatever a forelock is) and generally feel like one of the oppressed classes.

You presume Mr Wimp owns the house – and legally he does.

However he doesn’t own it outright.

Instead, like any financially savvy landlord, Wimp bought the house with an interest-only mortgage. He repays no capital, and in fact as house prices go up he remortgages every few years, increasing his debt on the house and rolling the equity released into new deals to buy more houses.

Buying, growing, releasing equity, and re-investing capital that’s leveraged through Other People’s Money – i.e. mortgages – is the heart of most property enrichment schemes. It gives Mr Wimp access to financial firepower that he could probably never have amassed in his lifetime from saving alone.

And Mr Wimp enjoys another great benefit from using interest-only mortgages to finance his properties.

The interest he pays on a mortgage can be offset against the rental income you pay him, in order to reduce his taxable profits.

For this reason, a landlord will typically try to keep his or her interest-only mortgage payments at about the same level as rental income. This way they can effectively reduce their tax liability on the rental income to zero. (Especially as he also gets to make deductions for wear and tear and the like).

When the mortgage – and hence the capital owed – comes due after 25 years or so, a landlord would usually aim to either sell-up the property and repay the mortgage, pocketing the difference, or else refinance the property with a new mortgage.

The alternative strategy – steadily amassing equity in a property by gradually buying it outright with capital repayments – would over time reduce the mortgage interest bill. This would therefore increase taxable profits – and taxes paid – as there’s less interest paid to offset against the rental income.

Of course a landlord might choose to own a property outright for other reasons – such as avoiding having to sell or re-finance in 25 years – but from a near-term tax efficiency perspective, a big interest-only mortgage is the way to go.

(Capital gains tax is another matter altogether. Whereas an owner-occupier can sell her home free of capital gains tax, a landlord is liable for taxes on capital gains).

It’ll cost you extra

As a renter, instead of you using a big mortgage to buy your property, your landlord has taken out a big mortgage to own the same property and to rent it to you.1

However in both cases you – the occupier – is servicing the mortgage.

  • If you own the property, you’re repaying your mortgage to the bank, likely over 25 years, and probably repaying capital as as well as interest.
  • If you rent the property, you’re paying your landlord’s mortgage, which is likely interest-only, via your rental payments.

Typically the rent paid to your landlord will cost you more than if you bought the same property via an interest-only mortgage.

This is because landlords aren’t in it for charity, and they want to make a profit.

Note: An interest-only mortgage is the correct kind to use for like-for-like comparisons between the different options, because it ignores capital repayments. Such repayment of capital is a separate issue (really it’s a form of saving).

Consider a two-bed property that costs £200,000 to buy:

  • A 4% interest-only mortgage costs £666 a month over 25 years.
  • Your landlord might charge say £750 rent a month– which is an effective rate on £200,000 of 4.5%.

By renting, it’s as if you’re paying a slightly more expensive interest-only mortgage than the landlord, and in addition you’ve hedged out house price gains and falls.

You’ve given up security of tenure in the deal, too.

On the other hand, you didn’t have to put in a deposit, so your free capital can be earning money elsewhere.

In addition, your landlord has to account for wear and tear to the property, whereas you can call him up for a new boiler. There’s also a risk that if you move out he won’t immediately find new tenants, forcing him to cover the gap in payments from his savings.

But you can’t bang nails into his walls.

However he paid all the transaction costs of buying the property. You just paid a month’s rent as a deposit.

And around and around we go…

The point is there’s a mix of pros and cons.

Lording it up

The key idea I wanted to get across today is the relationship between your rental payments and the landlord’s mortgage.

But here’s a few consequences to think about.

One very strong case for home ownership is to be your own landlord

If someone wants to rent you a property, then clearly they think it’s worth at least the monthly interest-only bill to do so, plus profit coming from either the surplus over the mortgage from the rent or gains in house prices, or both.

But as I mentioned, as well as any profit margin and an allowance for wear and tear, a landlord also has to charge a higher rent to cover the risk that a tenant doesn’t pay up or of a gap between tenancies.

As a homeowner you are effectively letting the property to yourself and these things are under your control. So unless you’re a member of a 1970s heavy metal band with a penchant for throwing TVs out of windows, you’re your own ideal tenant. By buying and renting the property to yourself, you get a better deal, because you pocket the profit margin, and you’re not paying extra to cover those overheads and unknowns.

Owning a home is more tax efficient than renting one

It’s true that UK home buyers no longer get mortgage interest tax relief, and that does put the landlord at a slight advantage from that perspective. However on the portion of your home that you own you’re effectively paying monthly rent (as imputed rent) free of tax issues. In contrast if you were renting you’d have to find the money to pay for the whole house each month out of taxed income.

For instance, if you own £100,000 of that £200,000 house, then you might have say £750 of ‘imputed rent’ that you don’t actually pay, and equally that you don’t have to find out of your taxed income. (This is a weird concept I know, so read the Wikipedia page on imputed rent).

Your home is also free of capital gains tax if you sell, so if you downsize to a smaller place or leave the property market, you don’t pay tax on any money that’s released. Landlords gains will be taxed.

Presumably, in a rational market the landlord takes that future tax liability into account when setting rents. So as a homeowner you should be able to make the maths work more comfortably than the landlord can.

Money NOT in property is NOT automatically dead money

I hope this post is another way of seeing that money spent on rent is not ‘dead money’.

Whether you rent or have a mortgage, you’re still paying an interest bill.

Equally, even if you’ve paid off your mortgage, the capital locked up in your home is not being invested elsewhere. And that has an opportunity cost.

Now I happen to believe most people do much better owning their own home than with shares, which is the only asset class likely to keep up with UK house price inflation over the long-term.

But if you’re a skilled investor who can earn, say, 10-15% a year from investing on average, then it might be worth renting from a landlord, even at an effectively higher interest rate, in order to avoid having to sink a big deposit into a property. You’d invest instead of paying off a mortgage. You’d have to be investing in an ISA or a SIPP to match the CGT-free nature of owning your own home.

Keep in mind though that a home bought with a mortgage is a geared investment, and those are very hard to beat with ungeared investments – presuming house prices keep going up at historical rates, of course. (If house prices fall for 20 years you’ll be laughing).

You might not be ready or able to buy yet

The reality is that not everyone can buy, even if monthly mortgage payments would be lower than their landlord’s monthly payments plus their mark-up (aka their rent). They may not have a deposit, or they may not be considered a good credit risk by a bank.

This has always been true for many 20-somethings – the controversy today is that it’s true of many people in their 30s and 40s, too.

A lot of it comes down to house prices

I have danced on a pinhead above discussing how a landlord may make a few more quid from rent after costs and so on. In reality, most landlords who got into the game in the 1990s have made out like bandits from house price appreciation, compared to any profits they made from rent.

Most old-time landlords say price appreciation should always the eventual goal, but when buy-to-let mortgages and legislation changes first democratized being a property mogul, it was also common wisdom that you should get at least a 10% yield on your purchase price.

Today yields are far smaller – more like 4-7% – but then mortgage rates are also far lower. Ultimately, winners and losers will likely be decided by the trajectory of the UK property market over the next 10-20 years – the ‘option on house prices’ I mentioned that a renter gives up to a landlord.

None of this is rocket science, but I hope it’s revealed a few of the semi-hidden dynamics of renting versus buying a home.

Please note: Constructive discussion about the mechanics of the UK property market in the comments would be great. Tirades about greedy landlords / young renters who spend all their deposit on iPhones / how the UK is going down the toilet unless we vote UKIP will probably be deleted.

  1. As I said before, we will leave any rights and wrongs of this for another day… Head to HousePriceCrash if you can’t wait, rather than arguing it here please. []

The case for the profitability factor in your portfolio

The profitability (or quality) factor boasts a number of traits that makes it particularly interesting for passive investors:

  • Profitability beat the market by 4% per year between 1963 and 2011.
  • It’s strong in large cap equities – a rare treat for a return premium.
  • It’s particularly powerful when partnered with investments in the value and small cap premiums because it’s negatively correlated with both.
  • Profitable equities tend to suffer less in a downturn than the total market.

Profitability works by concentrating on the firms that exhibit traits which are suggestive of rude business health in the future. It’s a bit like looking a potential mate up and down and determining their fitness according to the size of particular dangly bits. On an individual basis, you’ll often be disappointed, but apply the profitability criteria to enough candidates and on aggregate it seems to work.

The real power of profitability though may come from combining it in a portfolio with other financial steroids like value funds.

US Professor Robert Novy-Marx revived interest in the profitability factor with his work showing that a dollar invested in the US market in July 1973 grew to over $80 by the end of 2011.

But if you’d invested it in value and profitable equities instead, then that dollar would have grown to $572 (before expenses)

That’s a 615% increase.

Tempting.

The Holy Grail of diversification

Profitability works best in a multi-factor portfolio

The combination works because profitable companies are generally larger and more highly valued by book-to-market ratio than traditional value equities.

The outcome of holding them both is the holy grail of diversification: negatively correlated assets.

When profitable companies are on a roll, value firms tend to flop, and vice versa.

Bring together those complementary behaviours, and you have a portfolio that’s better able to resist a severe dip – because one of the factors should buffer you against the misfortune of the other.

This means you’re taking less overall risk in your portfolio, even though both factors are risky in and of themselves.

Big profits are beautiful

The large cap tilt of profitability also means it’s likely to bear up when small caps are going through a rough patch.

This is important for practical reasons, too. It’s hard for UK passive investors to invest in truly small cap equities. Most so-called small cap funds tend to invest more in mid caps, in reality.

Yet premiums like value, momentum and size are usually more powerfully present among smaller equities.

This means that while a return premium may deliver eyebrow-raising returns on paper, the reality of real-life investing is that those theoretical numbers can be leeched away if you have to invest in funds that don’t capture the most potent sources of return, such as micro cap equities.

Funds are also undermined by their management and transaction costs and their inability to easily short poorly performing equities, in comparison to the theoretical returns offered by the premiums as touted by academics.

Happily though, the paper Global Return Premiums on Earnings Quality, Value, and Size shows that a long-only portfolio1 can deliver strong returns by combining value and profitability.

This twin tilt beat the market by 3.9% among large caps, and 5.8% among small caps.

In comparison to a pure value tilt, the addition of profitability added 1.2% to the large cap returns and an extra 1.8% to small caps.

The effect becomes more pronounced still when you throw momentum into the mix, as this factor is negatively correlated with value and has a low correlation with profitability and small cap.
