One name seeing unusual options activity
is Limelight Networks, Inc. (NASDAQ:LLNW). Trade-Alert is highlighted buying at the April 4 call ahead of the company's earnings release on April 19. One would infer this is bullish activity, betting on a post-earnings rise from the digital content solutions provider. LLNW shares were last seen trading down 3.1% at $3.76.
One of the top performers on the Nasdaq is Turtle Beach Corp (NASDAQ:HEAR), as the stock makes another huge move higher. The shares were last seen trading up $12.8% at $4.41, echoing last week's post-earnings rally. The $3 level, home to the 320-day moving average, appears to be a level of technical support.

Stitch Fix Inc (NASDAQ:SFIX) is a major loser on the Nasdaq, trading down 9% at $21.12. The shares have been
trading in a tight range all year, with the $19-$20 area containing the pullbacks. Options traders don't seem concerned, as calls are trading at four times the expected pace.
