"There's a time and a place for everything."

It might have been your mother, your spouse, or your lawyer, but somebody, sometime, has said those words to you. I've certainly heard them before, but I'd never thought I'd think them myself -- but that's where I am. I'll come out and say it: this just might be the time and the place to invest in large cap stocks.

I love to invest in companies that are small, obscure, disliked -- loathed, even. Frankly, I like my chances in that hunting ground. It's a lot easier to have a different opinion on a stock when there are only a dozen other serious investors even looking at it. I sometimes think of large-cap investing as a hunting contest in which everybody else has machine guns and I have a slingshot.

That said, a number of large cap stocks just look plain old cheap. Here are three I'm considering for my Young Gun Portfolio.

National Grid: Lighting up
National Grid
(NYSE: NGG), owner of most of the electric grid in the U.K., and much of the grid in the northeastern U.S., is not only a large-cap, it's a utility! Hardly my "Young Gun" bread and butter, but I am not ideological about my investing style -- I am always open to great opportunities in any form.

Opportunity might be just the word to describe National Grid right now. After the company diluted shareholders to raise $4.6 billion in new capital last year, many investors fled. For new investors, though, the stalwart company just got interesting. That money was raised to fund infrastructure upgrades (is it any surprise that our power grids need upgrading?), and regulators, who control National Grid's rates, are increasingly allowing them to raise prices, in part to fund the investments. The upgrades should make the company's operations more efficient (read: cheaper) in the future, and while we wait for that to play out, investors can sit back and enjoy a whopping 6.1% trailing dividend yield.

Diageo: A toast
(NYSE: DEO) has been a favorite company of mine for some time, and it remains a frequent place for me to park extra cash. The $46 billion purveyor of alcoholic beverages specializes in "premium" beverages. Premium in the alcohol biz basically means above average, but not the ultra expensive stuff. Not Popov, but not Grey Goose, either. Think Smirnoff vodka, Captain Morgan rum, Johnnie Walker whiskey, and Jose Cuervo tequila -- and that's just the first round. Diageo's beverage arsenal runs deep -- the company commands eight of the world's top 20 alcohol brands.

The magic of Diageo is in its distribution network, which runs globally. Adding new products to that distribution network is cheap and easy, and the incremental benefits to Diageo are substantial. Yet, despite years of massive free cash flow generation, by my model Diageo's price tag looks pretty reasonable. I still have more work to do, but right now Diageo is near the top of my watch list.

Microsoft: Soft price for software?
(Nasdaq: AAPL) may now be the second largest company by market cap in the world (think about that for a moment), but when it comes to earnings, Microsoft's (Nasdaq: MSFT) nearly $20.6 billion in profit over the last year still handily sticks it to Steve Jobs & Co.'s "scant" $14 billion.  Yet the stock charts will tell you a different story: Apple is up almost 4,000% from a decade ago, while Microsoft's shares are, well, about where they were back then.

The market can leave even behemoths like Microsoft for dead, but the software giant is anything but. Sure, Bing is still bleeding money, and the Xbox hasn't exactly been a cash cow, but sales of Windows and Office brought in over $18 billion in revenue last year each. Microsoft remains dominant in both the operating system and productivity software domains, and at just 10 times free cash flow, I'm taking a second look.

Young Gun hunting big game?
The Young Gun Portfolio definitely has a small-cap bent, but we go where the opportunities are, and at the moment we are feeling like big game hunters. I'll be continuing my research on these companies, and, as always, I'll tell you before I make any trades.
