From Motley Fool:
Investors can be a moody and shortsighted bunch. A company mildly disappoints on some near-term metric and they abandon its long-term story by selling off its shares. That said, patient long-term investors actually stand to benefit from this moodiness because they can pick up shares of a great long-term story at a pretty hefty discount. That’s exactly what we see in three companies currently trading right around their 52-week lows. While all three have some near-term obstacles to overcome, as the longer-term stories play out it could drive strong outperformance for investors picking up shares at these low prices.
