An old axiom warns investors not to “catch a falling safe”, a reference to the fact that a falling stock is not always a bargain. For every solid company whose stock is experiencing a temporary downturn, another is punished by the market for very good reasons and may not recover. To “buy low and sell high” successfully, it makes sense to find undervalued stocks that are trading for less than they should. The trick for investors is separating a temporary stock pullback from a prolonged – and perhaps irreversible – downturn.
