Carrizo Oil Inc. (CRZO)

[Timothy Smith]

Carrizo Oil & Gas (NASDAQ:CRZO) is one such company whose stock has taken a beating over the last few months.

In fact, since early July, the shares of this small-cap diversified producer valued at $1.8 billion have declined by nearly 30%, underperforming a majority of its peers.

But this weakness can be great buying opportunity.
