you can find out what the short ratio is on a stock. RDWR is NOT being heavily shorted. Go to the link below and scroll down to the table at the bottom. on the right hand side you will see something called the "Short Ratio". This number would be higher if there was a large number of shorts in relation to longs. http://biz.yahoo.com/p/r/rdwr.html Now, you can click on the link below to see AMZN's profile page and look at the Short Ratio here. It is much higher. This indicates a larger number of shorts in relation to longs than in RDWR's case. http://biz.yahoo.com/p/a/amzn.html The good news is that RDWR is moving up not because of some temporary short squeeze but because there is buying interest (though the volume indicates it is not intense). This is all good as it indicates that there is less hype than there was before last quarter's earnings. Money entering before earnings is mostly speculative. Money entering after earnings is from REAL INVETORS who will buy and hold. I prefer the latter as it pays off better in the long run. BUY, HOLD, GET RICH!
