Anybody can make money when stocks are going up, and if you know how to sell stocks short, you can profit when stocks drop, too. But what the heck are you supposed to do in a flat market?

Of course, the market has seemed anything but flat lately. After the market meltdown in 2008 and early 2009, the stock market rallied more than 80%. But in April, stocks started to correct, and there's increasing tension between those who think the rally could resume and others who believe that we're headed back to the lows.

That kind of tension is a recipe for a volatile market that goes nowhere. Consider: After all these gyrations, the market's right back where it was trading in September 2008, just when the market meltdown was getting under way. All told, if you've held stocks since then, you've probably seen a pretty flat performance despite those big swings along the way.

But there's a great strategy that can help you make money even when the stocks you own end up in pretty much same place they started.

Where do I sign up?
Before you get too excited, though, let me point out one thing: This strategy uses options. If you're like many investors, you probably associate options with high risk. Yet used the right way, options can actually reduce your risk -- and that's something this strategy strives to achieve.

The covered call option is one of the simplest low-risk options strategies out there. It lets you earn some extra income from your portfolio while also retaining some of the upside if your stocks keep rising.

To use a covered call, you sell a call option on particular individual stocks you already own. That gives the investor who buys the option from you the right to purchase your shares of stock from you at some predetermined point in the future. In exchange for that right, the buyer pays you a premium -- which you get to keep, no matter what happens in the future.

Often, those premiums are pretty big. If you focus on high-growth companies that many believe will soar, then you can often get paid a lot for writing covered calls. Consider these three candidates, each of which has seen both their earnings and their stock prices grow quickly in the past year:

September $21

1.76

Silver Wheaton (NYSE: SLW)

Those premiums amount to 5% to 9% of the stock's value -- a nice return over a few months. Moreover, the options shown still let you participate in some of the upside if the shares keep rising.

On the other hand, another good way to implement the covered call strategy is with dividend stocks. The premiums aren't generally as high, but the dividends you'll get paid while you hold your shares will help offset the lower option income:

Chevron (NYSE: CVX)

October $30

0.63

Procter & Gamble (NYSE: PG)

October $62.50

You'll see that those premiums are lower, from 2% to 5% of share price. But each has a dividend yield of at least 3% to further boost your income.

Moreover, you can often use the strategy over and over again. That lets you collect new premiums each time, enhancing your income even more.

As with any appealing investment strategy, there's a trade-off. In exchange for the premium you receive for writing the option, you risk having to sell your shares if they go up in price. If you choose the right options, though, you'll guarantee yourself a profit even if that happens.

Why do it?
Obviously, the covered call strategy works best when:

  • You want to keep owning shares of a stock.
  • You think it will hold its value over time.
  • Even though it's attractive now, you don't think its price will rise too much between now and when the option you write expires.

In a sense, covered calls give investors a no-lose scenario: Either you get some extra cash to hold onto shares you already want to own, or you get paid an instant profit in a relatively short period of time. It boosts your income in down markets and locks in gains during bull markets. Moreover, it's a relatively simple introduction to options, which can help you with your portfolio in many ways.
