As an investing geek, I enjoy tracking the market's ever-changing moods. I get a kick out of watching Wall Street swoon or soar based on the latest scrap of macroeconomic data. It's even better to watch the Gucci-loafer set's reaction when a company misses or exceeds earnings estimates by some marginal amount. Was the result already priced in? Was it a genuine surprise?

Inquiring minds wanna know!
It depends on who you ask. Last Friday, for instance, Schlumberger (NYSE:SLB) checked in with a forecast-besting earnings report. The news caused the stock to pop up, but that rise had dissipated by the time the bell rang yesterday. Biotech concern Gilead Sciences (NASDAQ:GILD) went the other way, with last Wednesday's better-than-expected announcement leading to a gain of some 6.3% by the time Wall Street turned off the lights on Tuesday.

Geek out
Still, while as an investing geek I'm intrigued by Mr. Market's mercurial ways, as an actual investor, I want nothing to do with them. Well, next to nothing anyway. I do own a handful of individual stocks, but the lion's share of my nest egg is invested in Grade-A mutual funds for a simple reason: I hate losing money.

Funds aren't immune to downturns, of course, but they're a lot less risky than individual stocks, which have a bad habit of behaving irrationally. Funds, meanwhile, are more even-keeled and logical. Indeed, if you do your homework and focus on common-sense criteria like fees, strategy, and whether a fund manager invests his own moola alongside that of his shareholders, you can go a long way toward identifying those funds that can both grow and protect your nest egg.

Call it a two-for-one
That's the premise we've been operating under at the Fool's Champion Funds investing service for more than three years now. So far, all of our recommendations have made money for members, and one of my favorite funds has had exactly one losing year since opening for business in 1999. That occurred in 2002, when it shed less than 2% during a year that saw the S&P 500 fall by more than 22%.

With nearly 70% of its assets stuffed into just 10 names, the fund appears quite concentrated. One secret of its success, though, is that nearly 17% of the fund's moola is plunked down on Warren Buffett's Berkshire Hathaway (BRK-B). That single holding provides additional exposure to an equity portfolio that includes Procter & Gamble (NYSE:PG), Anheuser-Busch (NYSE:BUD), and Comcast (NASDAQ:CMCSA). Nike (NYSE:NKE) has made Buffett's -- and therefore this fund's -- grade, too.
