Facts are facts: After many years of small-cap dominance, the big boys are back.

True, it's the value-oriented mega-caps that have bellied up to the bar with the most gusto, with the likes of Fannie Mae (NYSE:FNM), Duke Energy (NYSE:DUK), and ExxonMobil (NYSE:XOM), for example, besting both the S&P 500 and the small-cap-centric Russell 2000 over the last 12 months. That's also true of Chevron (NYSE:CVX) and Verizon (NYSE:VZ), which have racked up gains in excess of 40% over the period. AT&T (NYSE:T) and Alcan (NYSE:AL), meanwhile, have earned more than 60%.

'Bout time, if you ask me. Indeed, cherry-picked overachievers aside, large caps look like the market's sweet spot right now -- at least for investors looking to buy quality on the cheap. If you want to lay a foundation for long-haul success as 2007 nears its mid-point mark, large caps in the aggregate -- and large-cap growth in particular, for reasons I explain here -- warrant a spot on your further-research list.

Or so says me
To be sure, Mr. Market can move in mysterious ways, frequently paying little heed to the laws of valuation gravity. It's precisely for that reason that I think world-class mutual funds are the best way for investors to proceed. With funds, you can allocate your nest egg across the market's various cap ranges and its growth/value spectrum with little in the way of muss or fuss.

And here's the beautiful part: Whether the market behaves rationally or not, you and your portfolio can be prepared. With funds, it's relatively light work to say, "I'll have this much in large caps, this amount in mids, and how 'bout a dollop of the little guys? Thank you very much." After you've made those calls, you can quickly be about the business of, you know, having a life beyond refreshing your browser every five seconds to see how wealthy you are -- or aren't. 

With funds it pays to be very choosy
If you're reading this, chances are you know very well just how hard it is for actively managed funds to beat the market, a truism that might incline you toward index funds. A little knowledge, however, can be a dangerous thing: Index funds are market laggards, too -- investment vehicles that are virtually destined to lose to their benchmarks each year by about the amount of their annual costs. Indexes themselves don't have expense ratios, after all. Index funds, however, do.

So, how can you get what you pay for with an investment vehicle where less -- when it comes to expense ratios -- really is more? Excellent question. As the Fool's resident fund geek, I've found that strategy, managerial tenure, and whether managers "eat their own cooking" by investing their own money alongside that of their shareholders are all key criteria. If a manager isn't willing to the take the plunge, after all, why should you?

Criteria in action
Not coincidentally, those are among the main points I consider when making recommendations for members of the Fool's Champion Funds service -- and so far, so good. Indeed, since we first opened for business more than three years ago, all of our recommendations have made money for shareholders, and we've beaten the market by a double-digit margin to boot.
