Restaurant chain Darden Restaurants (DRI), first discussed here on June 25, 2009, at a price of $32.78, has formed a double-top near $51. So now would be a good time to consider taking some profits off the table, if you're in near $33.

However, those investors who can tolerate the risk can maintain their full position and go for an bigger gain, but investors should keep in mind that Darden probably won't clear $60 in 2011. The potential upside is still adequate, but not fantastic.

Companies continue to file quarterly reports late in the season, and a few are poised to spread some early holiday cheer for investors this week. Analysts surveyed by Thomson Reuters expect strong earnings results from Nike (NKE), Bed Bath & Beyond (BBBY) and Darden Restaurants (DRI), among others. Here's a quick look (for more details, see the DailyFinance Week in Preview).

Analysts forecast Nike's fiscal-second quarter earnings to come in at 88 cents per share, a 13.6% increase from the same period of last year. The world's leading athletic footwear maker also is expected to post revenue of $4.8 billion for the three months that ended in November. That's 9.3% more than the same period a year earlier. Note that Nike's earnings have not fallen short of consensus estimates in the past five quarters.

After a volatile May, many folks are looking to companies that pay a regular dividend as a way to limit their risk and provide a bit of steady income. While it's important that the payout is substantial in these type of income investments, it's also important for investors to focus on stocks raising dividends because this helps guarantee that a company won't leave shareholders in the lurch and slash payouts when times get a little tough. After all, if you buy in for the quarterly payday, the last thing you want is for your holdings to slash their dividend payouts or let them languish without any increases.

For all you income investors out there, here are three stocks from the last week that just raised dividends and could be good additions to your holdings:

Restaurant chain Darden Restaurants (DRI), first discussed on June 25, 2009, at a price of $32.78, will likely be among the sector's survivors. Here's why.

In the three months that ended in January, Williams-Sonoma (WSM) saw strong holiday sales, declared a quarterly dividend, and announced the retirement of its CEO. Analysts expect the San Francisco-based home products retailer to report that fiscal fourth-quarter earnings more than doubled from the same period of last year to $0.74 per share. Revenue for the period is expected to be 6.2% higher to $1.1 billion. For the full year, the forecast calls for earnings of $0.81 per share (+56.8%) on $3.1 billion in revenue (-8.3%). Williams-Sonoma earnings results have been better than expected in recent quarters -- beating consensus estimates by more than 200% in the third quarter.

Shares of Darden Restaurants (DRI), which I first wrote about on June 25, 2009 at a price of $32.78, have raced ahead. Is there any upside left? Let's see...

Look for Darden's same store sales (in this case, restaurants) to rise 2-3% in fiscal 2011, after a roughly flat fiscal 2010. That doesn't sound like much of a revenue increase, but in the hard-hit restaurant sector, that's adequate.

Not all companies in these love-struck industries are good buys. Here are 10 stocks to break up with this Valentine's Day.

• 1-800-Flowers (FLWS): A good gift, but a poorly run company that has posted a loss for three of the past four quarters.
• Hershey (HSY): Missing out on the Cadbury merger was not so sweet for Hershey.
• Cardiac Sciences (CSCX): It's hard to have a heart for a company that fails seven out of my eight fundamental screens.

While most investors are fretting the markets recent contraction, you can be quite confident that "my pal Warren" has a smile on his face, as does Peter Lynch, Ken Heebner, Bill Miller, Bruce Berkowitz, and any number of fellow value investors that know now may be a time of opportunity. That is because they have the experience and understanding to pounce when they have a chance to buy things cheap.

This is the fourth installment of my series to discover just that: cheap stocks. If you would like to get on board from the beginning then review the initial post which screened for stocks with lower than market average P/E ratios, see Serious Money: Market Looks Cheap to Me -- 35 Stocks. In the second installment, I looked at yield and PEG ratios: Serious Money: Still Cheap Market -- 35 Stocks + Yields & Growth. Then I moved on to the the P/S and P/CF metrics in Serious Money: Cheapest Stocks Yet -- From 35 to 26, cutting nine stocks.

Is the market overpriced? Maybe it is cheap, or perhaps it is fairly valued. This is the third in a series examining the issue. Still, it has been my contention that it does not make any difference because no matter how the market is valued as a whole, there are plenty of cheap stocks out there to accommodate a large amount of capital allocation even this deep into a bull run.
