According to Nasdaq, if the shorts want to cover, it would take three weeks of current trading volume for them to close out their short positions. It doesn't take a Jim Cramer to figure out short interest this high can become explosive after a strong earnings report. Even a widely subscribed positive press release can send shares soaring.

Two recent short squeeze examples include Tesla Motors ( TSLA) and First Solar ( FSLR). Both companies traded at price multiples above Pitney Bowes and were targets of short-sellers. Both companies surprised Wall Street with positive news.

First Solar doubled in less than two months when shares climbed from under $28 to an intra-day $59 peak. Tesla Motors accelerated from $40.50 on April 9, 2013 to over $100 today. Short interest is rocket fuel for a stock that delivers unexpected terrific news. Short-sellers are considered the smart money on Wall Street for a good reason -- they usually get it right.

Pitney proved short-sellers who failed to take gains in December were wrong. If the company demonstrates to the entire market the shares are undervalued, a short squeeze above $20 is the likely next stop. The next significant resistance testing level is the 200-week moving average near $19.50.

With almost 40% of shares shorted, there is certainly enough fuel to get there if the company can light the fuse.
