Weekend reading: Relatively predictable

Good reads from around the Web.

When engaged in the Fool’s Errand of active investing [1], one must always think relatively:

… and so on.

As for passive investing, its appeal is founded on a principle of relativity. By aiming to get just the market return – minus the lowest possible costs – you’ll very likely do relatively better than most active investors who aim to beat the market but who pay a high price for trying to.

Combining these two lines of thinking is an article over at Morningstar [2] about John Bogle’s concept of ‘relative predictability’ .

The author John Rekenthaler argues it’s Jack ‘Father Of The Index Fund’ Bogle’s least appreciated insight:

Relative predictability – a phrase that Bogle mentioned in passing to me, in a conversation last week – is something altogether different.

The relatively predictable asset is the asset that behaves as expected, given the performance of the financial markets.

Relative predictability has nothing to do with the usual statistics that measure absolute levels of risk. It cannot be measured by standard deviation.

Relative predictability is unrelated to volatility.

In its realm, cash can be highly risky and stocks can be fully safe.

Read on [2] to discover its applications. The concept is a wonderful piece of investing philosophy that had me screaming “Yes! Yes! Genius!” as it cleared up a few fuzzy notions that I’ve been obsessing over for years.

Although if you get out more and have a rich home life, your mileage may vary…

Enjoy the weekend!

Product of the week: Degiro [15] is a new-to-the-UK broker that offers share trading for less than £2, reports the Telegraph [16]. Think that’s cheap? Pah, it enables you to trade US shares for €0.50! However it doesn’t yet offer ISAs and the firm operates under Dutch regulation.

Book of the week: As a long-time Tesla shareholder, I’ve already drunk the Kool-Aid. But I’m still finding plenty to marvel at in Ashlee Vance’s biography of Elon Musk [31]. I suspect it’s not exactly a Tell All, but there are enough unflattering anecdotes to keep credible the otherwise unbelievable tales of building space rockets, dreaming of trips to Mars – and reinventing the automobile industry as almost a side-project.
