If, after 2008, you're still looking at the stock market as a way to fund your retirement, most people probably consider you a few congressmen short of a bailout. (Zing!) It's probably progressed far beyond the point of people refusing to make eye contact with you. In all likelihood, your dog won't look at you, either.

Yes, it's tough proclaiming yourself a bull after a year in which every bull became a fine selection of juicy steaks.

But there are a few perks. Like getting the profits that come from buying stocks at what could be some of the best prices you'll ever see.

A brief history of 2008
Last year was a fantastic demonstration of what happens in a highly leveraged world when everyone needs liquidity at the same time.

Anyone who borrowed to buy mortgage-backed securities needed cash as mortgage values plummeted. Ambac (NYSE:ABK) and the other bond insurers needed cash as the mortgage-backed securities they were guaranteeing fell. Banks needed cash to maintain their capital ratios as defaults escalated. AIG (NYSE:AIG) needed cash to balance its losses in credit default swaps. Hedge funds needed cash to fund redemptions and reduce leverage as assets declined.

The problem is, when everyone needs cash, the only way to get it is to sell off assets. And that's what investors did, dumping almost every asset class with the exception of ultra-safe Treasuries. The stock market took it on the chin.

An overreaction
That's not to say that the market collapsed simply because everyone cashed out. The problems in our economy are real. We've seen huge bankruptcies, the unemployment rate has spiked to higher than 9%, and consumer confidence is low. Companies that need cash are finding it tough to raise money at reasonable costs.

But the carnage in the market isn't limited to the shaky companies that are likely to suffer the most. The S&P 500 contains the biggest, most successful, and most stable businesses in America. Yet more than 94% of the companies in the S&P 500 fell during 2008. More than 30% lost greater than half their value! Certainly, deteriorating business prospects are responsible for some of that drop. But based on valuations, it seems likely that stock investors are selling because they must. Like everyone else, they need the cash.

And that's a really great thing if you're not one of Wall Street's forced sellers.

The sweet spot
Large-cap value stocks could be the best way to exploit this opportunity. I'm not just talking about slow-growing companies trading at low single-digit earnings multiples, but also compellingly cheap growth stocks.

For instance, these days, the universe of large-cap value stocks includes Google (NASDAQ:GOOG). Google has huge barriers to competition, $19 billion of cash on its balance sheet, an innovative culture, and a 19% estimated annual growth rate going forward, and it's trading for about 19 times trailing-12-month free cash flow. At these prices, Google is a large-cap value stock.

So why are large-cap value stocks a great investment these days? Not because these stocks are certain to outperform the other categories under all circumstances, but because they present the ideal tradeoff between risk and reward in these troubling times.

While there's a good chance that the economy will start showing signs of life sometime in 2009, there's a possibility that things will get even worse. When you're betting your retirement, you should own businesses that can survive the worst-case scenario.

Low risk, high reward
Generally, large-cap stocks fit that criterion. They have the most stable cash flows, the most well-known brands, the greatest economies of scale, and the best chance of recovering from mistakes.

Would you put your money on McDonald's (NYSE:MCD) to withstand a depression, or Krispy Kreme (NYSE:KKD)? Would you bet on Wal-Mart (NYSE:WMT), or Dillard's (NYSE:DDS)? These two examples may be somewhat hyperbolic, but it's absolutely true that powerhouses like McDonald's and Wal-Mart are far more likely to survive than companies with smaller moats. The big guys simply have the financial clout, the economies of scale, and the proven, winning business models.

In normal times, you'd really have to pay up for these sorts of dominant companies. But thanks to forced selling from investors struggling to raise cash, right now you can buy some excellent businesses extremely cheaply. The S&P 500 is trading at around 16 times forward earnings, its lowest earnings multiple in more than a decade.

What's more, due to the poor economy, the earnings of these powerhouse companies will be depressed in 2009, which means that the normalized earnings multiple is even more compelling. Large-cap stocks are extremely cheap, and I believe they will offer superior returns over the next few years.

The Foolish bottom line
Of course, you still have to be careful -- as 2008 has shown us, you can't just throw a dart at the S&P 500 and expect to avoid a blow-up. You still need to pay attention to balance sheets and how much cash companies are bringing in during these troubling times.

But if you're alert, you can find the stocks right now that will pay for your retirement. So now is a good time to start buying large-cap value stocks.
