The May 13 , 2011 short interest data is now out and there were some significant changes in many of NASDAQ’s high-priced leaders.  Some short selling went up and some went way down.  We have tracked the short interest in Amazon.com, Inc. (NASDAQ: AMZN), Apple Inc. (NASDAQ: AAPL), Baidu, Inc. (NASDAQ: BIDU), F5 Networks, Inc. (NASDAQ: FFIV), First Solar, Inc. (NASDAQ: FSLR), Google Inc. (NASDAQ: GOOG), Netflix, Inc. (NASDAQ: NFLX), Priceline.com Incorporated (NASDAQ: PCLN), QUALCOMM Incorporated (NASDAQ: QCOM), and Wynn Resorts Ltd. (NASDAQ: WYNN).  We compared to the short interest of May 13 to April 29 and we have added in color on each one as far as general short-selling trends and past short interest reports.

Amazon.com, Inc. (NASDAQ: AMZN) saw a large gain in short selling as the May 13 settlement date showed 10.163 million shares in the short interest versus the April 29 settlement date of 7.717 million shares short.  This was the highest reading since last November. 

Apple Inc. (NASDAQ: AAPL) saw a drop to 11.666 million shares at the May 13 date versus 13,349,219 shares as of April 29.  The prior reading was the highest short interest going back a full year, but now this is back to what has been normal in 2011. 

Baidu, Inc. (NASDAQ: BIDU) picked back up in short selling… May 13 saw 6.364 million shares versus the April 29 reading of 5.893 million shares.  This is the highest reading since mid-February. 

F5 Networks, Inc. (NASDAQ: FFIV) saw another drop as the May 13 settlement date showed 2.826 million shares short versus 3.069 million shares at the April 29 settlement date.  The short selling activity in F5 is actually again at the lowest reading going back one year.
