Here are some interesting quotes from ‘Risk & Chance’ (Dowie and Lefrere) that have a relevance to trading and speculation more generally:

Henslin (1967) notes …dice players behave as if they are controlling the outcome of the toss.  One of the ways they exert this is to toss the dice softly if they want a low number, or hard for a high number.  Another is to concentrate and exert effort when tossing.  These behaviours are quite rational if one believes that the game is a game of skill. 

As a trader I wish I could figure out what portion of my trading results can be attributed to luck, and what portion to skill. The problem is that trading seems to be a game of both skill and luck, so we spend half our time figuring out just how hard we should be throwing the dice. Splitting skill from luck is a problem for all speculators, but high frequency traders can find out much sooner than low frequency macro traders, who only take a few positions each year. In the latter case, it may be close to impossible to look back to a macro trader’s career and make this determination with any reasonable level of certainty.  

De Charms(1968) stated that “Man’s primary propensity is to  be effective in producing changes in his environment.  Man strives to be a causal agent, to be the primary locus of causation for, or the origin of, his behaviour; he strives for personal causation.

The polar opposite of mastery is helplessness. (more…)

John C Bogle classics- Two Books

#  #  #  #  #  #  #  #

Two of John C. Bogle’s books on investing have now been designated classics. They have been added to the Wiley Investing Classics series, joining such titles as Lombard Street, The Go-Go Years, Reminiscences of a Stock Operator, and The Alchemy of Finance.

Bogle on Mutual Funds: New Perspectives for the Intelligent Investor was originally published in 1993. Since then, investments in mutual funds as a whole have surged eight-fold, and Vanguard’s fund assets have grown 25-fold. They are now 50% larger than the entire industry was when Bogle wrote this book.

To readers who are familiar with Vanguard’s philosophy, this book may seem, as Bogle himself admits, “old hat.” That is only natural. A book isn’t designated a classic if only a handful of people ever read it. Or, in the case of investing books, if its message never resonated.

Bogle on Mutual Funds had two missions: to steer the individual investor in the right direction and to cajole the mutual fund industry into adopting more investor-friendly policies. On both fronts Bogle has had considerable success, even he would like to see even more reform.

His advice to the investor is pretty straightforward, but his arguments are definitely worth rereading, or reading for the first time. People have the bad habit of throwing money at the market without knowing anything about the basics of investing. So they invest in the wrong things, or at the wrong time, and curse their bad luck. No investor can be called “intelligent” who doesn’t understand the principles Bogle articulates in this book. The investor may still decide to try his hand at outperforming the market, but he should know what he’s up against.
