As my colleague Karla Yeh pointed out over at ONN.tv earlier today, Biogen Idec (BIIB) saw some unusual options trading in the wake of its positive earnings surprise before the bell.

BIIB gapped higher at the open, jumping almost 2% out of the gate. Less than a half hour into the trading day, large blocks of roughly 4,000 contracts each traded at four March strikes: the 45-strike put, the 50-strike put, the 55-strike call, and the 60-strike call. It appears as though this investor sold the March 50/55 strangle (the 50 put and the 55 call) and simultaneously purchased the March 45/60 strangle (the 45 put and the 60 call).

A short strangle is typically employed when the investor expects the underlying instrument to stay range-bound; a long strangle is used by traders who expect a sharp move in either direction. In this case, with one of each crossing the tape as part of one strategy, it can be referred to as an iron condor.

UBS (UBS) was one of the hardest hit from the financial crisis, but the company is showing signs of stabilization. In the latest quarterly report, the firm posted profits of $1.3 billion. Actually, it was the first reported profit in a year.

Of course, the cost-cutting was a big help (roughly 16% of the workforce). But there was also a nice tax credit during the quarter.

The company's new CEO, Oswald Grübel, definitely understands how to turnaround financial institutions. After all, he had considerable success at Credit Suisse (CS).

Yesterday Hasbro, Inc. (HAS) reported 2009 fourth quarter and full-year results.

For the fourth quarter 2009, the Company reported net revenues of $1.38 billion, an increase of $144.1 million or 12%, compared to $1.23 billion a year ago. 2009 fourth quarter revenues grew 7% excluding a $55.4 million positive impact of foreign exchange. The Company reported net earnings for the quarter of $165.6 million or $1.09 per diluted share, an increase of $72.0 million or 77%, compared to $93.6 million or $0.62 per diluted share in 2008.

The strong results in a bad year support my contention that today's stock market, even in these uncertain times, does have plenty of bargains.

Coventry Health Care (CVH - option chain) shares are rising Tuesday after the company reported a fourth-quarter profit of $109.08 million, or 74 cents per share, on revenue of $3.42 billion. Analysts had forecast a profit of 56 cents per share on revenue of $3.49 billion. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on CVH.

CVH opened this morning at $23.81. So far today the stock has hit a low of $22.83 and a high of $23.99. As of 11:40, CVH is trading at $23.22 up 78 cents (3.5%). The chart for CVH looks bullish bullish and S&P gives CVH a positive 4 STARS (out of 5) buy ranking.

CVS Caremark (CVS), which competes with Walgreen (WAG), Rite Aid (RAD), and Wal-Mart (WMT), posted fourth-quarter data on Monday. Sales increased 7%, and adjusted earnings per share from continuing operations (excluding, in addition, a penny per share relating to a tax benefit) came in at 78 cents -- good for a growth rate of over 11%. That bottom-line performance matched analyst projections, according to our earnings preview.

As we all know, matching expectations is sometimes the death of a stock. The market has no conscience when it comes to mercilessly punishing an equity for not going beyond the call of the analysts. However, CVS actually did pretty well yesterday, rising 5% by the end of the session; the move was backed by healthy volume.

Electronic Arts Inc. (ERTS) was down in the after-hours session by over 9% on the heels of the gaming publisher's Q3 report. Non-GAAP sales were off by over 20%. Adjusted income came in at 33 cents per share. This was two cents higher than expectations according to my earnings preview, but a lot less than the 56 cents per share earned in the comparable frame.

The press release mentions the lower quantity of titles released during the holiday season as being a driver of the decline in revenue (a tough European market was also cited). That may be, but it doesn't absolve EA of its fundamental challenges.

I love the media sector, so Tuesday, February 9, will be an exciting day for me. After the market finishes its trading activities, we'll get reports from two entertainment companies: one's a big player in Hollywood, while the other would like to be just as big someday.

Let's start with the big gun. The Walt Disney Corporation (DIS) has first-quarter numbers all set to go, and investors are hoping for an unambiguous beat on the bottom line. The call is for net income to fall somewhere around 39 cents per share, according to Earnings.com. Kind of lousy, considering the Mouse made 41 cents per share in last year's Q1.

Hasbro (HAS - option chain) shares are rising today after the company reported earnings this morning, posting a fourth-quarter profit of $165.56 million, or $1.09 per share, on revenue of $1.38 billion. Analysts had forecast a profit of 81 cents per share on revenue of $1.34 billion. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on HAS.

HAS opened this morning at $33.65. So far today the stock has hit a low of $33.53 and a high of $35.19. As of 11:40, HAS is trading at $34.99 up $4.18 (13.6%). The chart for HAS looks bullish and S&P gives HAS a positive 4 STARS (out of 5) buy ranking.

CVS Caremark Corp. (CVS), the largest retail pharmacy chain in the U.S., is scheduled to discuss its fourth-quarter financial results in a conference call Monday, Feb. 8, at 8:30 AM (ET). An audio webcast of the call will be available at the company's website.

During the three months that ended in December, CVS announced share buybacks, named a new head of HR and provided H1N1 flu shots nationwide. Analysts surveyed by Thomson Reuters are looking for earnings for that period of $0.78 per share. That compares with $0.65 per share in the previous quarter and $0.70 per share a year ago. Revenue for the fourth quarter is expected to be 8.6% higher than a year ago to $26.2 billion.

Quarterly reports continue to roll out this week, with results due from Allstate Corp. (ALL), Coca-Cola Co. (KO), Marriott International Inc. (MAR), Molson Coors Brewing Co. (TAP), New York Times Co. (NYT), Pepsico Inc. (PEP), Sprint Nextel Corp. (S), Viacom (VIA), Walt Disney Co. (DIS) and many others. Here's a look at a few of the companies that analysts surveyed by Thomson Reuters expect to be the biggest earnings gainers this week.

Analysts are looking for Coinstar Inc. (CSTR), which distributes coin-counting, DVD-rental, and other self-service kiosks, to report that its fourth-quarter earnings more than doubled from a year ago to $0.32 per share. Revenue for the three months that ended in December is expected to have jumped 26.1% to $329.2 million. The analysts' forecast for the full year calls for earnings of $0.94 per share (+46.8%) on $1.2 billion in revenue (+25.9%). Coinstar has beat earnings estimates in the past three quarters, by as much as six cents per share.

Insurance broker Aon (AON) reported a 2% increase in organic revenue in its EMEA region in the fourth quarter, due largely to its performance in emerging markets. The only country in the region where it said revenue fell was the UK. Overall revenue for the fourth quarter of last year increased 9% to $2.1 billion, though organic revenue dropped 2% worldwide. Revenue from insurance broking operations gained 8% (to $1.7 billion), representing a decline of 1%.

Currency trends led to an increase in operating expenses of 10% for Aon, which rose $162 million to $1.8 billion. Of this, $96 million came from currency-related issues. Restructuring expenses related to the Benfield acquisition were up $88 million to $175 million.

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Aol Inc. (AOL) reported a better-than-expected Q4 profit and said its revenue also topped estimates.
• Burger King Holdings Inc. (BKC) higher Q2 earnings topped analysts' estimates but same-store sales fell.
• Clorox Co. (CLX) higher Q2 earnings beat expectations and it lifted its full-year earnings guidance.
• Comcast Corp. (CMCSA) Q4 earnings more than doubled and beat Wall Street expectations, but shares fell.
• Gap Inc. (GPS) shares jumped after it forecast earnings above analysts' expectations, boosted by January sales.

Electronic Arts (ERTS), a software maker whose colleagues include Activision Blizzard (ATVI), Microsoft (MSFT), Nintendo (NTDOY) and Sony (SNE), will be reporting third-quarter numbers on Monday, Feb. 8, after the market closes up shop. This is going to be an interesting one.

I doubt there are many market watchers out there who aren't aware of the problems in the video game industry; 2009 was not the best of years for the sector, and investors are hoping that 2010 will execute a rebound. However, EA has specific fundamental problems. The declines seen in its share price cannot be solely sourced to the macro conditions of the current console cycle.

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Aflac Inc. (AFL) posted better-than-expected Q4 earnings, though revenue fell short, and offered rosy guidance.
• Avon Products Inc. (AVP) posted Q4 earnings growth that met analysts' expectations but shares sold off.
• Cisco Systems inc. (CSCO) higher Q2 earnings topped the consensus estimate but cash flow fell.
• CME Group Inc. (CME) fell short of analysts' Q4 profit expectations, resulting in price-target cuts.
• ExxonMobil Corp. (XOM) posted better-than-expected Q4 earnings and revenue that boosted shares.

THQ (THQI), a video game publisher whose colleagues include Activision Blizzard (ATVI) and Electronic Arts (ERTS), reported very good news this week. For the third quarter, non-GAAP income was 35 cents per share. In the comparable frame, a loss of 14 cents per share was posted.

This obviously represents a vast improvement, although it should be noted that it didn't come on the back of a big sales increase. On a reported basis, the top line was flat, and on a non-GAAP basis, it was down more significantly. This is important to note, because it would have been nice to have read about a revenue expansion, considering the way the gaming industry has been suffering.
