Analyst Upgrades: Weight Watchers International, Inc., Shake Shack Inc, and Take-Two Interactive Software, Inc.

Analysts are weighing in on dieting specialist Weight Watchers International, Inc. (NYSE:WTW), burger joint Shake Shack Inc (NYSE:SHAK), and video game giant Take-Two Interactive Software, Inc. (NASDAQ:TTWO). Here's a quick roundup of today's bullish brokerage notes on WTW, SHAK, and TTWO.

• WTW is set to jump more than 20% at the open -- to the delight of this media mogul -- following the company's earnings beat and upwardly revised guidance. As such, Barclays upped its price target to $17 from $14. The shares have been red-hot recently, surging close to 150% since mid-October to trade at $16.93, powered by a high-profile investment. Short sellers are likely under duress, and an unwinding of short positions could fuel Weight Watchers International, Inc.'s gains moving forward. Specifically, 57.5% of the stock's total float is dedicated to short interest, which would take roughly one month to repurchase, at WTW's typical trading volume. 

• SHAK is feeling good vibes this morning, as an upbeat earnings report prompted Barclays and Cowen to lift their respective price targets to $48 and $47. In addition, the company raised its full-year forecasts, while cautioning growth will moderate in 2016. As such, Shake Shack Inc is pointed over 5% higher pre-market, after closing at $51.11 yesterday. Should these gains materialize, they could spur other analysts to lift their opinions on the stock. In fact, not a single one currently rates SHAK a "buy," and the security's consensus 12-month price target of $45.60 sits well below its current perch.

• TTWO is also getting some love from Wall Street, on the heels of a strong earnings report and upwardly revised full-year outlook. Specifically, Jefferies, Baird, Wedbush, and Mizuho raised their price targets on the outperformer, which has already rallied nearly 18% year-to-date to sit at $33.05. Ahead of the bell, Take-Two Interactive Software, Inc. is up 4.4%, putting it on track to open at a new all-time high. The shares could get an additional lift from unwinding negativity in the options pits. At the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX), TTWO has racked up a 10-day put/call volume ratio of 6.48 -- higher than all other comparable readings from the past year.
