Northern California-based Peet's Coffee & Tea (PEET) is a different flavor of coffee stock, really cashing in on premium herbal tea offerings and specialty foods as well as providing a great cup of java.

Jellies, jams, candies and pastries are just part of Peet's diverse product line. This has helped the company find a broader customer base, appealing to those with a sweet tooth as well as caffeine junkies and iced tea fanatics. The results are clear in Peet's bottom line.

For millions of Americans, and indeed for millions around the globe, there's nothing like a piping hot cup of coffee to help kick-start the day. It's the beverage of choice for the hordes on Wall Street, many of whom rely on a strong cup of java to help propel them through a stressful trading day.

But Wall Street pros don't just relegate their relationship with coffee to what's inside their mugs. For many professionals, as well as for many individual investors, coffee is more about buying and selling shares of the best coffee stocks out there.

The past month has been nirvana for the shareholders of Diedrich Coffee (DDRX ), at least for those who held on. The company was the object of a fierce bidding war from Green Mountain Coffee Roasters (GMCR) and Peet's Coffee (PEET).

But today, the hostilities are over as Green Mountain finally won the battle. The company has agreed to pay $35 per share for Diedrich (the bidding started at $26). Keep in mind that -- about a year ago -- the shares were trading at 21 cents.

Diedrich Coffee (DDRX) continues to be the belle of the ball in the caffeinated beverage sector. Green Mountain Coffee Roasters (GMCR) Wednesday hiked its offer to acquire Diedrich, raising the bid from $32 per share to $35 in cash. The deal's total value now stands at $290 million.

"We are eager to start realizing the benefits of this transaction for our shareholders as quickly as possible, and therefore after careful deliberation, we determined to enhance our proposal to $35.00 per Diedrich share," explained Lawrence J. Blanford, CEO of Green Mountain Coffee.

Today started out strong and stayed positive all day, even if some commented that the highs were not held. The weak dollar helped commodities and helped stocks. A 10.1% October sales rise by the National Association of Realtors by those trying to get the home buyer tax credit didn't hurt either. Ditto for a reiteration that the recession is over.

Here were today's unofficial closing bell levels:

Dow 10,450.04 +131.88 (1.28%)
S&P 500 1,106.13 +14.75 (1.35%)
Nasdaq 2,175.96 +29.92 (1.39%)

Just about a year ago, the shares of Diedrich Coffee (DDRX) were trading around 30 cents. Since then, it's been an incredible ride as the shares have reached $33.

Over the past month, Diedrich Coffee has actually been the target of a heated buyout battle from Peet's Coffee & Tea (PEET) and Green Mountain Coffee Roaster (GMCR). In fact, Monday Peet's upped its bid to $32 or $265 million. Investors think the bidding is not over, though.

Some investors shy away from small stocks, thinking they are too volatile and risky. But BusinessWeek takes a look at such stocks and finds some that could offer a lot of potential for growth.

It can be hard to find small companies that have great growth potential. Since most Wall Street analysts ignore smaller companies, it is often tough for investors to find the research that they need in their selection process, so they have to rely on their own research in order to find that perfect small cap stock.

One thing to look for when examining small cap stocks is a long and established track record. The downside to this approach is that these stocks are not going to be the next "big thing" and bring you huge profits in the short run. These stocks are the ones that typically serve a niche market, and perform that service successfully. While these will not make you rich overnight, they are fairly reliable companies you can look to for nice and steady returns. If you are the type of investor who likes to buy and hold, these are the small cap stocks for you.
