Troubled movie renter Blockbuster has been looking for a buyer, and we learn today that DISH Network (DISH) has won the auction for the company, with a deal valued at $228 million in cash.

Blockbuster was once the biggest name in video rentals, but it has been unable to keep up with changes in the market created by companies such as Netflix (NFLX) and Redbox.

Place Whirlpool Corporation (WHR), first discussed here on March 13, 2009, at a price of $34.47, in the not-for-squeamish-investors category.

Appliance manufacturer extraordinaire Whirlpool's stock over-corrected last summer, formed a bear-hug, bottomed at/near $69.50, then recovered to about $90 during the winter -- before recently sliding back to $84. Translation: a roller-coaster -- something that one generally does not see with an industrial player. Even so, I still like WHR here. But hold on to your hat if you own the shares -- the bumpiness could continue in 2011.

And if you haven't already, consider taking some provides off the table with WHR, if you're in at/near $34.50.

Lowe's (LOW) is the world's second largest retailer of home improvement products after Home Depot (HD). Walmart (WMT) and Target (TGT) also cater the home improvements market.

OpenTable(OPEN) has come a long way since Chuck Templeton envisioned the idea in 1998 after observing the difficulty his wife faced while trying to book a dinner reservation by phone. Today, it is the leading provider of free and real-time online restaurant reservations for users looking to book reservations online as well as a reservation and guest management solution for restaurants. The company is comfortably ahead of its competitors like Urbanspoon, owned by IAC/InterActiveCorp and UK-based companies liveRES Ltd and Livebookings Ltd. It also seems to have hit the right note with its decision to take Groupon head-on by selling third-party restaurants coupons through its website.

We currently maintain a $94.90 price estimate for OpenTable, which is about 10% below the stock's market price.

Charles Schwab Corporation(SCHW) recently announced its decision to acquire optionsXpress in a friendly all-stock deal, as the company takes aim at the growing foreign exchange market.

Our $19.74 price estimate for Charles Schwab implies a roughly 10% premium to the stock's market price.

Fourth quarter GDP ended on a uptrend, coming in at 3.1%. The state of the economy was healthy and it looked like growth would continue to match or exceed Q4. Based on that scenario, Bank of America (BAC) analyst Ethan Harris, forecast first-quarter 2011 GDP to come in at 3.3%.

But in the few short months of 2011, the world is getting turned upside down. The conflict in Libya has cut OPEC oil production and sent oil prices skyrocketing. In turn, the price of gasoline is nearing $4.00 per gallon. And food processors are raising prices due to higher raw commodity prices. These two factors have put a dent in the household budget.

Bank of America (BAC) is a pretty big player in its industry; it's got brand equity -- everyone has heard of it. How is its stock looking these days?

At the time of writing, shares could be had for $13.44. The 52-week low for the company is $10.91; the 52-week high is $19.86. That's a tight range, and as one might imagine, this company has been a vehicle for traders trying to ride whatever volatility is available at any given time.
