Buzz Stocks: T-Mobile US Inc, Weight Watchers International, Inc., and Intersil Corp

U.S. stocks are wallowing in red ink ahead of the bell, as oil sells off following a dismal global supply outlook. Meanwhile, among specific names in focus are telecommunications stock T-Mobile US Inc (NASDAQ:TMUS), weight management firm Weight Watchers International, Inc. (NYSE:WTW), and integrated circuit specialist Intersil Corp (NASDAQ:ISIL).

• TMUS said pre-orders for Apple Inc.'s (NASDAQ:AAPL) iPhone 7 hit the highest on record over the weekend. The shares of TMUS are pointed higher ahead of the bell, and the stock remains a long-term outperformer. Specifically, TMUS stock has surged more than 38% since tapping an annual low of $33.23 in mid-February, and closed last night at $45.93 -- just north of its rising 80-day moving average. While options traders have grown increasingly optimistic, short interest surged 12.1% in the most recent reporting period. Should the shares of T-Mobile US Inc continue to climb, there's plenty of fuel for a short-covering rally to help the stock extend its recent quest for record highs. At TMUS' average pace of trading, it would take nearly nine sessions to cover these bearish bets.

• After just three years on the job, WTW CEO James Chambers said he will resign, effective Friday, Sept. 30. A trio of executives will cover the position until a search committee -- which includes board member Oprah Winfrey -- finds a replacement. After closing last night at $10.36, the shares of Weight Watchers International, Inc. are pointed 3.4% lower in electronic trading, and will likely explore year-to-date lows. This projected price action is just more of the same for the stock, though, considering it's surrendered 63% since notching a 52-week peak of $28.05 last November. Short sellers are betting on even more losses, too. Short interest jumped 4% in the most recent reporting period, and now accounts for a whopping 62% of WTW stock's available float.

• In the latest round of M&A news, shares of ISIL are set to pop 9.3% out of the gate, after Japan's Renesas Electronics Corp said it will purchase the chipmaker in an all-cash deal valued at $3.2 billion. This equates to roughly $22.50 per ISIL share -- a 13.9% premium to last night's settlement at $19.76, and territory not explored since 2008. On the charts, the security had rallied nearly 55% year-to-date through Monday's close, and hit an eight-year high of $20.31 one week ago.
