We have many stocks on the move this morning. The following are the stocks to watch for active traders this Wednesday: Buffalo Wild Wings Inc. (NASDAQ: BWLD); Facebook Inc. (NASDAQ: FB); iRobot Corp. (NASDAQ: IRBT); InvenSense Inc. (NYSE: INVN); Netflix Inc. (NASDAQ: NFLX); Panera Bread Co. (NASDAQ: PNRA); RF Micro Devices Inc. (NASDAQ: RFMD); SIRIUS XM Radio Inc. (NASDAQ: SIRI); Sycamore Networks Inc. (NASDAQ: SCMR); Tempur-Pedic International Inc. (NYSE: TPX); United Therapeutics Corp. (NASDAQ: UTHR); and Zynga Inc. (NASDAQ: ZNGA). We have shown the moves and given a brief summary on each.

Buffalo Wild Wings Inc. (NASDAQ: BWLD) is going to be down handily and shares are indicated under $75 after closing at $83.46 on Tuesday. Profits failed to meet estimates. Store growth looked slower as well. The prior 52-week range is $58.08 to $94.81.

Facebook Inc. (NASDAQ: FB) has soared after earnings, and we have even seen two analyst upgrades from Citi and Bank of America; shares are up 20% at $23.55 and trading volume is very active.

iRobot Corp. (NASDAQ: IRBT) is way down and trading even worse than last night, with shares under $20.00 against a 52-week range of $19.09 to $38.33. While it grew, it said with earnings that the 2012 outlook for D&S has deteriorated and it expect further declines in 2013. Volume is light but shares are around $19 after closing at $22.64.

InvenSense Inc. (NYSE: INVN) was up 1.6% yesterday. That was before its earnings report. The company said that Steven Nasiri will step down as CEO and chairman effective immediately. Shares are down almost 12% at $12.49, but shares were down as much as 18% at $10.20 last night, against a 52-week range of $8.25 to $22.35.

Netflix Inc. (NASDAQ: NFLX) was a total disappointment on the earnings and growth front. Shares are down a whopping $11.30, or 16.6%, at $56.90 in trading volume that does not feel as active as it would have a year ago or so.

Panera Bread Co. (NASDAQ: PNRA) bucked the bad news trend from restaurants. Along with a 27% gain in its profits, guidance was positive and ahead of estimates. Shares are up 5.4% at $169.00 in the after-hours session against a 52-week range of $114.58 to $175.26.

RF Micro Devices Inc. (NASDAQ: RFMD) rose yesterday, rose in the after-hours and also is up even more this morning. Revenue rose sequentially to $209.7 million and sees the current quarter at $245 million due to improvements. Shares are now up by almost 16% to $4.55 this morning, and its 52-week range is $3.45 to $7.89.

SIRIUS XM Radio Inc. (NASDAQ: SIRI) is down 2.4% at $2.80 after Mel Karmazin said he was resigning. Make no mistake: this was a John Malone push-out in that fight for control of the company.

Sycamore Networks Inc. (NASDAQ: SCMR) is selling a unit, looking to sell another line and then plans to close down the company and distribute its assets to shareholders in a special cash dividend. Adios! Shares are down more than 7% at $5.55 so far this morning.

Tempur-Pedic International Inc. (NYSE: TPX) has bed bugs if its earnings and guidance are any read. Shares were down 4.6% yesterday and the stock is down 18.6% at $25.95 so far this morning. Posting a quarterly loss and a weaker-than-expected forecast is crushing this stock all over again. Keep in mind that the 52-week range is $20.70 to $87.43.

United Therapeutics Corp. (NASDAQ: UTHR) is trading down 12%, or almost by $6.50, to $46.79 in active trading. The company received a complete response letter for its Oral Treprostinil new drug application, which means that the FDA did not approve its application.

Zynga Inc. (NASDAQ: ZNGA) shares are up 5% at $2.32 with a strong Facebook. After the layoff news yesterday, it was hard to not notice that Zynga is a dog, but still a dog that trades close to its book value now.
