Major March Short Interest Increases (CSCO, LOGI, MCRL, PRXL, PTEN, SPLS, JAVA, TROW, YRCW)

We routinely look over major changes in short interest from period to period.  While the more frequent twice-monthly reporting is conducted by exchanges, it sometimes gives a little insight into the psyche of traders and trends.  The most important issue to look at is in the larger and more active names that have large positions that grew rapidly in percentage terms.

We screened many different names after the short interest data came out last night from NASDAQ, so we looked for a minimum of 5 million shares short and we looked for those names whose short interest grew by more than 30%.  These are not all of the names, but here is a representation of the screen:
