According to the principle of value investing, people should pick stocks that appear to be trading for less than their book value. Which means buy when the stock price drops. There's another group of people who trade oppositely. They follow the market trend to buy and sell. The more a stock price has risen, the more they buy-in.
So which way is more "right"? The fact is, the reality is all grey areas. There are very few black and white answers. Don't rid yourself of ideology and narrowness. There are hundreds of ways to get rich if you stay open-minded. Different methods can be used in different scenarios.
