Buying Stocks Is Easy, Selling Is The Hard: 7 Rules to Manage Risk

Buying stocks is easy; the hard part is knowing when to sell. I read an excellent article recently by Michael Batnick on his trials and tribulations in owning a stock. To wit:

“Now let’s talk about a company that I did care enough about to buy and lost money on. What do you call a stock that was down 58% and then fell 27% in a day? Zillow.”

The primary tenant of investing is that if you are going to put capital at “risk” in a “speculative transaction,” be prepared to lose. We have all been there.

However, where I partially disagree with Michael’s analysis is this:

“‘Buy low, sell high’ is one of the most garbage pieces of financial ‘wisdom.’ Most of the time when you buy low, you end up selling lower. Jon Boorman taught me this a long time ago but sometimes you have to relearn what you already know. Jon wrote, ‘If you want to own the strongest stocks, buy the strongest stocks. Buy something that’s already doing what you want it to. Going up.”’

Like most “financial wisdom” that has survived the ages, it gets lost on young investors who have never lived through an actual bear market. More importantly, there is a vast difference between “momentum” and “fundamental” investing.

There Is No Long-Term

There is a distinction that I must make here. Michael’s quote of Jon Boorman talks about “momentum” investing, or rather, short-term trading. Here is his precise quote.

“Buying a stock at x+1 can be a lower risk trade than buying it today at x. Forget buy low, sell high. When something is falling, it’s more likely to keep falling than it is to reverse, and vice versa. It’s called momentum, and along with value, it’s one of the most empirically proven anomalies to academic theory that the Nobel Prize winners wish would go away. Note to self: Look into buying value stocks that show upward momentum."
