If you take bad investment advice from others, you may end up selling a stock too early or engaging in unprofitable investing strategies
Most investor sayings and clichés have at least a hint of truth. But they can still lead you to take good or bad investment advice, depending on how you apply them.
For instance, you’ll sometimes hear investors say that you shouldn’t fall in love with your stocks. This seems to make sense. You should keep an open mind on your investments, rather than falling in love with them and holding them forever, despite any adverse changes in their business or the field in which they operate. However, investors sometimes use this tidbit of advice as a justification for selling a stock that has shot up unexpectedly.
Unexpected strength in a stock you like is a bad reason to sell
The stock may be stronger than you expected because you underestimated the growth potential or competitive advantages that led you to like it in the first place. Experienced investors can tell you that some of their best stock picks started going up out of proportion to what they expected, and kept outperforming for years. By the time the first significant “dip” or setback comes along in a stock like this, it may have tripled.
