The Motley Fool's CAPS investing service is another great way for investors to work together to beat the market. Among other features, CAPS lets users blog about their picks, investing strategy, market view, favorite rugby team, or whatever floats their boat.

As CAPS blogging catches on, players add more great content on a daily basis. I've dug through the past week's posts to find some of CAPS' best insights. With room for only seven posts here, I can't possibly cover all of the great stuff in the CAPS blogosphere, so when you're done reading these, I highly recommend that you head over to CAPS and check out some more.

401(k) retirement plans for small business

Transocean: the deeper they drill the higher the stock will go
Though some investors bullish on oil may head toward the likes of Exxon (NYSE: XOM) or BP (NYSE: BP), others know that better profit potential may lie elsewhere.

A great long opportunity
Though CAPS All-Star DemonDoug is pretty bearish on the economy, he sees a good opportunity at recent Altria (NYSE: MO) spinoff Philip Morris International (NYSE: PM). As he notes, not only does the stock pay a nice dividend, but it's also the type of company that you should be able to hang onto for a long time.

Let homebuilders run on tax cut legislation -- short retailers
CAPS blogger dexion10 thinks that it may be time to ease up on that Lennar short, now that the government may be stepping in to lend those poor, unfortunate homebuilders a hand. Where should shorts head instead? Dexion suggests looking for some of the most at-risk retailers, such as Finish Line.

And that's our roundup for this week. Be sure to check back next week for more great blogging action. In the meantime, why not head over to CAPS and add your two cents to the community pool?
