Even though we can anticipate billions of dollars in claims there still are buying opportunites.

Do you have any interest in insurance companies amidst the turmoil, disaster and current crises in Japan? A crises that followed so closely on the heals of the destruction of the New Zealand city of ChristChurch by a 6.3 magnitude earthquake. Perhaps you think this is even a poorer idea than catching that proverbial falling knife we are always hearing about when stock prices are collapsing.

Certainly there will be billions of dollars in claims. On the other hand, perhaps the burden will be spread around the globe to reinsurer's such that none is struck too hard and this is a buying opportunity. After all, when the dust settles, insurers will cry for mercy, and in particular, rate increases. It is also likely those that never saw the need for insurance have been awakened and demand will increase.

MetLife (MET - option chain) stock is trading lower today along with most other insurance companies this morning after the cost to insurers related to Friday's earthquake in Japan was estimated to be between $15 to $35 billion. Prudential Financial (PRU) and AIG (AIG) are also down so far in today's trading. Even if these insurance companies are actually on solid footing financially with regard to their expected claims, I expect investors could be frightened for several months to come, which could keep share prices depressed. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on MET.

MetLife reported a 36% increase in premiums, fees and other revenues from the insurance business outside of the U.S. in the year 2010, mainly due to the addition of about $836 million from ALICO's one month operations. MetLife acquired ALICO for about $15.5 billion from AIG as a part of its strategy to grow internationally. The acquisition has enabled MetLife to serve 90 million customers in over 60 countries and has significantly boosted MetLife's position as a leading insurance company in the U.S, Japan, Latin America, Asia Pacific, Europe and the Middle East.

Things look to be pretty quiet on the economic calendar this week. Here are the highlights:

• Tuesday: Weekly chain-store sales
• Wednesday: Federal budget balance for January
• Thursday: Wholesale trade data in December
• Friday: Trade balance in December and the weekly inflation survey

However, three iconic companies -- Walt Disney (DIS), Coca-Cola (KO) and Hasbro (HAS) -- highlight this week's quarterly results. Here's a look at what analysts surveyed by Thomson Reuters are anticipating from these and others.

For example, year-over-year earnings growth from big oil Chevron (CVX), ConocoPhillips (COP), ExxonMobil (XOM) and Royal Dutch Shell (RDS.A) are expected to be in double digits. The same is true of many other energy and mining concerns reporting this week: Allegheny Technologies (ATI), Alliant Energy (LNT), Arch Coal (ACI), Cliffs Natural Resources (CLF), CMS Energy (CMS), CONSOL Energy (CNX), DPL (DPL), Hess Corp. (HES), Minerals Technologies (MTX), Pioneer Natural Resources (PXD), PPL Corp.

Analyst Upgrades

• Auriga upgraded Leap Wireless (LEAP) to buy from hold following the company's Q2 results and analyst day, citing valuation, longer-term potential for consolidation and prospects for business improvements. Despite upgrading, the firm lowered its target for shares to $16 from $19.

By and large, earnings expectations remain high as earnings season rolls on this week. Analysts surveyed by Thomson Reuters expect double-digit annual earnings growth from Avon (AVP), Kellogg (K) and Whirlpool (WHR) to Chicago Mercantile Exchange (CME), DuPont (DD) and Northrop Grumman (NOC).

Big Oil steps into the earnings spotlight this week as well. Wall Street is anticipating big profit growth from BP (BP), Chevron (CVX), ConocoPhillips (COP), which we look at more closely below, Exxon Mobil (XOM) and Royal Dutch Shell (RDS.A), as well as from Apache (APA) and Occidental (OXY). Even Hess (HES) is forecast to have swung to a profit from last year's net loss.

Prudential Financial, Inc. (PRU), the Newark N.J.-based life insurance giant, is scheduled to release fourth-quarter financial results after the market closes Wednesday, and then to discuss those results in a conference call tomorrow, Thursday, Feb. 11, at 11:00 AM (ET). An audio webcast of the call will be available at the company's website.

During the three months that ended in December, Prudential saw management changes, sold its stake in a joint venture and declared an annual dividend. Analysts surveyed by Thomson Reuters are looking for earnings for that period to come to $1.11 per share. That compares with $1.59 per share in the previous quarter and a loss of $2.04 per share a year ago. Revenue for the fourth quarter is expected to be 6.9% higher than a year ago to $16.2 billion.

Analyst Upgrades

• Barclays upgraded Visa (V) to overweight from equal weight following the Q1 report and guidance. The firm raised its target to $97 from $91.
• Merriman upgraded AOL (AOL) to neutral from sell on valuation and better trends in online advertising.
• Barrington upgraded Idex (IEX) to outperform from market perform following the results on expectations the company's 2010 sales and profits will recover. The firm set a $36 target on shares.
• Credit Suisse upgraded Rio Tinto (RTP) to neutral from underperform and BHP Billiton (BHP) to outperform from neutral.
• Posco (PKX) was raised to overweight from neutral at HSBC.

Analysts surveyed by Thomson Reuters are looking for life insurance giant MetLife Inc. (MET) to report that its earnings rose 80.0% from a year ago to $0.95 per share for the three months that ended in December. Revenue, however, is expected to total $12.6 billion, which is down 10.1% from a year ago, during a fourth quarter in which it offered guidance and declared a quarterly dividend. The analysts' forecast for the full year calls for earnings of $2.89 per share (-25.7%) on $48.3 billion in revenue (-5.3%). This New York-based insurer's earnings results have been better than expected in three of the past four quarters, beating estimates by as much as 20 cents per share.

MetLife's long-term EPS growth forecast is 10.7%, which is better than that of competitor Prudential Financial Inc. (PRU), and its earnings multiple is 8.8x. The First Call consensus recommendation has been to buy MET for more than 90 days, despite a recent downgrade of the stock. The mean price target is $42.87. Shares have been trading between $32.00 and $40.00 since August and closed the week at $35.32.
