26 reasons your stock picks suck


Wade Meredith at Healthbolt.net recently posted the insightful "26 Reasons (Why) What You Think Is Right Is Wrong." His list made clear to me just why I'm not wealthy. See if you can spot your personal investment blind spots.

The bandwagon effect – The herd instinct, best illustrated by the tendency for a regular golf foursome to end up invested in the same stocks, and occasionally in one another's spouses.

The choice-supportive bias – Using rose-tinted glasses to view one's past investments. I seem to remember selling my Pets.com in early March of 2000, not September. Didn't I?


The disconfirmation bias – Our tendency to pick apart arguments of those we disagree with, while accepting at face value that which confirms our preconceptions. Everyone knew Apple Inc. (NASDAQ: AAPL) was headed to the scrapheap ten years ago, right?

Hyperbolic discounting – the exaggerated credit we give to the quick kill over long-term growth. Without hyperbolic discounting, how would churn brokers thrive?

The mere exposure effect – our tendency to overvalue stocks of companies with which we are familiar, i.e., "I bought Crocs Inc. (NASDAQ: CROX) stock because I look bitchin' in their shoes!"

The focusing effect – placing too much importance on one instance or attribute. Selling a fast food stock when someone reports finding a finger in the French fries.

The zero-risk bias – our tendency to niggle slight risk toward no risk while ignoring a huge exposure elsewhere. Using a pocket calculator to figure out a tip while maintaining a $5,000 balance on our 22% credit card.

The endowment effect – our tendency to value a stock more as soon as we buy it. A codicil I've noticed is we gauge the value of a product by how much we pay for it, not by its market worth. This is why bargain hunting for an engagement diamond can be counterproductive.

I'd like to add one to his list, too.
The Jim Cramer effect – the louder and faster an enabler talks, the more we credit what he says. I SAID, THE LOUDER...

I suggest checking out the entire list, and keeping it in mind the next time you have the impulse to call your broker.
