Weekend reading: Black Swan blues

Weekend reading

Excellent reading from the Worldy Wise Web.

Once upon a time, Black Swans were rarer than golden geese. But then Nicholas Taleb wrote his bestseller The Black Swan (not to be confused with the pouting Natalie Portman vehicle) and Black Swans have ever since been ruffling feathers everywhere.

I have nothing against Taleb’s dark tome, although I prefer his earlier Fooled by Randomness, which could genuinely change your investing life.

But I do object to the ceaseless reaching for the Black Swan metaphor whenever anything happens that someone doesn’t like the look of.

  • “A nuclear reactor has blown up – it’s a Black Swan event!”
  • “Reckitt Benckiser’s CEO resigns – another Black Swan!”
  • “The market is down today – Black Swan! Black Swan!”
  • “Why knew ISA rates would fall to 3%? Talk about Black Swans.”

No, please don’t talk about Black Swans, not until you can tell one from a duck.

Anyway, The Motley Fool ran such an excellent piece on spotting Black Swans versus red herrings that I’m making it today’s post of the week.

The author, Vincent Scheurer, writes:

The rule that all swans are white was never logically provable. However, the first person to see a real black swan (in 1697) immediately knew that the rule that all swans are white was wrong.

The point about the “Black Swan” in the modern sense of the word — the unexpected event with terrible consequences — is that it cannot be predicted in advance, which means that we as a society must take steps to ensure that its impact is minimised rather than spending all of our resources trying to stop it from happening in the first place.

That, in a nutshell, is why most of the efforts going into financial re-regulation are a waste of time.

How we rebalance the Slow and Steady portfolio

Our Slow and Steady model portfolio was especially designed to minimise costs and hassle for small, passive investors right down to its rebalancing strategy. But how exactly does that strategy guide our new purchases?

The Slow and Steady rebalancing strategy

The Slow and Steady portfolio is rebalanced as a matter of course on a quarterly basis with cash from new contributions.

So every three months, fund purchases are automatically calibrated to return the portfolio to its target asset allocation:

  • UK equity: 20%
  • Developed World ex UK equity: 50%
  • Emerging market equity: 10%
  • UK gilts: 20%

N.B. Developed World ex UK equity is split between four funds (due to the lack of a single, no-trading fee fund in the UK) as follows:

  • North American equity: 27.5%
  • European equity ex UK: 12.5%
  • Japanese equity: 5%
  • Pacific equity ex Japan: 5%
  • Total: 50%

Rebalancing is the act of pruning back your risk. Without it the portfolio could mutate into a much hairier beast if, for example, the emerging markets fund went on the rampage. Over years, the portfolio could end up with a much higher percentage of its value bound up in this risky asset class than the envisaged 10%, if we did stood idly by.

So when it’s time for the portfolio’s quarterly £750 new contributions, we buy more of the under-performing funds and less of the out-performers, and take advantage of mean reversion.

Rebalancing slo-mo replay

The first time the Slow and Steady portfolio was rebalanced its market value was £3,017.84

It’s important that the rebalance takes into account the new cash added, so:

£3,017.84 + £750 = £3,767.84 (total portfolio value after drip-feed)

How much of this total should then be allocated to each asset class?

A quick example should do the trick. The target allocation for UK equity = 20% of £3,767.84.

£3767.84 / 100 = 37.6784
37.6784 x 20 = 753.568

So we want £753.57 of UK equity in the portfolio once the new cash is added.

The value of UK equity in the portfolio prior to the new cash = £607.10

£753.57 – £607.10 = £146.47

£146.47 is the amount of UK equity we should buy to ensure the asset is rebalanced to its target allocation of 20%.

That calculation is repeated for each fund in the portfolio to determine how much of each asset class we need to buy.

Eventually the portfolio will grow too big to be entirely rebalanced by new cash. At that point we’ll need to sell assets that exceed their target allocation and use the proceeds to pump up assets that fall short.

That won’t cause the Slow and Steady portfolio any trading cost pain though (the bane of rebalancing) because we’re cannily invested in index funds that don’t trigger broker fees.

Weekend reading: Weather or not

Weekend reading

A short hallelujah to the weather, followed by some choice reading from around the web.

Incredibly, it’s sunny in London. What a difference it makes after all the snow, slush, and arctic blasts of what seemed a six-month winter.

Like health, you can’t really buy the weather. Yes, you can buy an aspirin, and yes you can emigrate to Australia. But you can’t dial up the sun on demand like a Domino’s pizza.

One quick way of re-appreciating your good fortune, weather-wise, is to visit a loved one in hospital. A person who can’t leave, ‘ideally’ (as in ideally for this experiment to work, not for your unfortunate acquaintance).

I’ve noticed long-term hospital residents often stare out of the windows when it’s sunny. Or at other times they turn their back on it, and seem unable to bear what they can’t enjoy. The more fortunate are wheeled to sit in some sunny spot besides the bins and the smokers on crutches, to feel the warmth on their skin. It’s a foreign holiday for them.

The incurable and the dying seem to inhabit windowless, weather-less rooms – I’ve seen this more than once in NHS hospitals. Perhaps there are logistical reasons. Perhaps it’s cruel. Or perhaps it’s some long ago learned wisdom about how best to let go.

The Slow and Steady passive portfolio update: Q1 2011

It’s time for the first trading update of the official Monevator, passive, model portfolio: The Slow and Steady portfolio.

We're up! Just.

The portfolio invests purely in index funds. The first purchases were made on December 31, 2010, with an initial lump sum of £3,000.

Another £750 of regular contributions are drip-fed in every quarter, and the latest purchases were made on April 1. An auspicious day if ever there was one.

In its first three months of life, the portfolio has inched up 0.59%, which amounts to a cash gain of £17.84. Who ever said passive investing isn’t a shortcut to fabulous wealth?

Actually, this move to profit is quite a turnaround, because I took a sneaky peek at the portfolio a few weeks ago, and it was haemorrhaging like an undercover cop in a Tarantino movie.

Events, dear boy, events

The markets were on something of a tear at year-end when we fed our initial lump sum into the financial wood-chipper. Since then we’ve been battered by bad news:

  • UK economic contraction in the final quarter of 2010.
  • Fears of overheating emerging markets.
  • Devastating floods in Australia.
  • Triple catastrophe in Japan – quake, tsunami, nuclear crisis.
  • Middle East uprising – the wisdom of the crowds writ large, but bad for short-term economic stability.

The upshot is that the Japanese fund has been hammered, the emerging markets have dipped too and the Australian-dominated Pacific fund has been dragged down in their wake.

The countervailing bright spot is the European fund, perhaps benefitting from belief in Franco-German determination to defend the Euro.

Scores on the doors

Here’s how the individual funds have fared over the last three months:

The Slow & Steady portfolio on April 1

What does all this tell us? Absolutely nothing of significance.

It’s fun to think about the trends and events that may have buffeted our funds over the last three months, but over a 20-year time horizon we’re relying on diversification, low cost funds and the efficiency of the markets to ensure we come out ahead. There’s nothing for it but to stick to the plan.
