With more than 5,400 stocks to choose from, the universe of investment possibilities is enormous so looking for stocks based on what you already know and own might be a path to pursue.

Motley Fool CAPS, the 180,000 member-driven investor community that translates informed opinion into stock ratings of one to fives, helps you focus your attention by providing you with a personalized Stock of the Day. Using its supercomputer, it looks at stocks currently in your active pick list and then scans stocks picked by highly rated players with lists similar to yours as well as industries in which you currently have active picks, and targets areas in which you already have an interest.

By pairing up the opinions of some of the top investors in the CAPS community, CAPS provides you with a handful of companies on which to begin your own due diligence and research.

Buy what you know No doubt based on my having weighed in on master limited partnerships like Inergy, L.P. (NYSE:NRGY), Enterprise Products Partners L.P. (NYSE:EPD), and NuStar Energy L.P. (NYSE:NS) that I rated to outperform the broad market indexes, the CAPS supercomputer thought I also might be interested in LinnCo LLC (NASDAQ:LNCO) , a unique business whose sole purpose is to turn complicated distributions from Linn Energy LLC (NASDAQ:LINE) into more easily digested dividends.

It was one of five Stocks of the Day it offered up for my consideration this week, and though it offers a tempting dividend that currently yields over 7%, just remember as smart as the CAPS algorithm may be, it's still just an algorithm. So be sure to look before you leap on any of its suggestions.

Pipeline to profits I've written several times about the care investors need to take when investing in master limited partnerships, since they are not all created equally. Although their genesis lies in fixed assets like oil and natural gas pipelines and storage facilities, companies have gotten creative by devising vehicles that stray from the toll road model originally envisioned.

Because MLPs like Plains All American Pipeline, L.P. (NYSE:PAA) and Kinder Morgan Energy Partners LP (NYSE:KMP) essentially collect fees for each barrel of oil or natural gas passing through their pipeline regardless of its price, their payouts are relatively safe, steady, and secure. But a relatively new breed of MLP has been developed that skews that model, and despite appearing similar on the surface, their payouts represent a greater degree of risk. They're heavily reliant on the price of the underlying asset to make their distributions, because it determines how much they produce.

Linn Energy as an oil and natural gas driller is one such MLP, as is coal miner Oxford Resource Partners, LP (NYSE:OXF), frack sand producer Hi-Crush Partners LP (NYSE:HCLP), and nitrogen fertilizer maker Rentech Nitrogen Partners LP (NYSE:RNF).
