Shorts might be hedging their bets on the Internet search titan

Traders are showing a distinct preference for calls on Baidu, Inc. (BIDU) and YRC Worldwide Inc. (YRCW), although you'd be hard-pressed to find two stocks more diametrically opposed on the charts. While BIDU is extending its long-term ascent, the shares of YRCW are lingering near theoretical support at zero.

Baidu, Inc.

Calls have been gaining popularity on BIDU of late. During the past five days, traders on the International Securities Exchange (ISE) have bought to open 10,523 calls on the Internet search issue, compared to 7,773 puts. The stock's five-day ISE call/put volume ratio of 1.35 confirms that speculators have been favoring bullish bets over bearish in recent sessions.

In fact, taking a slightly longer-term look, BIDU's 10-day ISE call/put volume ratio of 1.76 ranks higher than 95% of other such readings taken during the previous year. This elevated percentile rank suggests that options traders on this exchange have snapped up calls over puts at a faster pace only 5% of the time.

However, the stock's Schaeffer's put/call open interest ratio (SOIR) checks in at 1.08, in the 59th annual percentile. This reading points to a relatively modest amount of lingering skepticism among short-term options traders.

BIDU OI configIn the front-month series, call players have concentrated their efforts at BIDU's August 75, 80, and 85 strikes. These three calls are home to a combined total of more than 40,000 contracts. BIDU is currently trading right near $80, smack in the middle of these major call accumulations.

Elsewhere on Wall Street, short sellers have been adding new bearish bets on BIDU. Short interest rose by 5.8% during the most recent reporting period, and now accounts for 2.7% of the equity's float.

With short interest and buy-to-open call volume ramping up in tandem, it's quite possible that the option activity is related to increased hedging by the shorts. By purchasing out-of-the-money calls, short sellers can limit their upside risk for a relatively minimal upfront cost. If so, this would diminish the bullish sentiment readings suggested by BIDU's recent ISE stats.

After checking out the charts, it looks as though the shorts definitely have just cause to hedge their bets. BIDU has rallied more than 97% year-to-date, and the stock has outperformed the broader S&P 500 Index (SPX) by more than 23 percentage points during the past 60 sessions.

The equity's uptrend has been highlighted by solid trendline support. Since early February, BIDU has beat a steady path higher along its 10-day, 20-day, 50-day, and 80-day moving averages. The shares also recently broke out above short-term pressure in the $78 neighborhood, which could switch roles to act as an additional layer of support going forward.
