Mistake number 24: Do You Believe More Heads Are Better Than One?

One of the things Larry tries to teach people is about conventional wisdom when it comes to investing. Conventional wisdom is things that are generally accepted that no one questions because they typically apply in most fields.

Larry says that the problem with using conventional wisdom when investing is that investing is a very different endeavor because you’re not competing one-on-one against someone; you’re competing against the collective wisdom of the market. And the conventional wisdom is that more heads are always better than one. But when it comes to investing, too many cooks spoil the broth; therefore, more heads are not better than one.

To illustrate this, Larry quotes a study by professors Terrance Odean and Brad Barber, Too Many Cooks Spoil the Profits: Investment Club Performance. The study covered 166 investment clubs, using data from a large brokerage house, from February 1991 to January 1997. Here’s a summary of their findings, which include all trading costs:

  • The average club lagged a broad market index by 3.8% annually, returning 14.1% versus 17.9%.
  • 60% of the clubs underperformed the market.
  • When performance was adjusted for exposure to the risk factors of size and value, alphas (performance above or below benchmark) were negative even before transaction costs. After trading costs, the alphas were, on average –4.4% per year.

Larry’s advice is to invest conservatively instead of following the crowd. Diversify your portfolio, make any big bets, and you’ll be fine.

Mistake number 25: Do You Believe Active Managers Will Protect You from Bear Markets?

Larry admits that active managers start with an advantage headed into a bear market because the passive systematic investor is going to earn the return of the market; they’re not getting in and out of the market. The market may have done very well before the bear market. They would have rebalanced their portfolio, taken some of those chips off the table, and sold high. And when the bear market hits, if they stay disciplined, they get to buy low and can even outperform the very funds they invest in.

But active managers tout themselves to have the ability to get you out before the bear emerges from its hibernation and will get you back in before the bull gets into the arena again. So they can move to cash. However, there’s no evidence that active managers can protect you from bear markets.

Larry says the only way to help minimize the risks of a bear market and be safe is not to take risks. But then, you won’t get any actual returns, and reaching your goals will be hard. The next best thing is to hyper-diversify.
