If you didn't buy stocks at March's lows, you're probably feeling antsy to get back into the market before you miss any more of the recent rally. But if you're scared of buying at a potential top, there's a way you can earn potential profits while limiting your losses if the rally reverses itself soon.

Happy days are here again -- but for how long?
After the bear market of 2008 and early 2009, stocks turned the corner and never looked back. The S&P 500 is 80% above its March 2009 lows, and with the recession officially over, many believe that the economy is returning to normal and that stocks can continue to rise from here.

But of course, you've heard all this before. In early 2008, after the fall of Bear Stearns and the opening stages of the subprime mortgage crisis, bears had knocked stocks for a loop, with the S&P dropping 20% from its record highs of October 2007. Many concluded that the worst was over and started piling back into stocks again, pushing the S&P up nearly 15% by May and recovering a good chunk of its previous losses.

Buying in May turned out to be a huge mistake, though, because the biggest losses of the bear market were yet to come. Consider what happened to these stocks next:

Understanding these huge turnarounds is fairly simple. For financial stocks, the credit crisis lopped off billions from the value of toxic assets, impairing balance sheets and threatening their financial stability.

At the same time, the markets on which financial companies rely nearly stopped functioning, leaving them in a no-win situation. That also hurt Ford, which needs customers to have access to credit to purchase vehicles.

And with energy and commodities, the bursting of the commodity bubble that had sent oil prices to nearly $150 a barrel brought these former highfliers back down to earth in a hurry.

So if you're thinking about getting into the market now, you may be feeling understandably nervous about the potential losses if you're wrong. Is there any way to invest so that you'll get the benefits from a rebound without having to take huge risks?

A call for higher profits
If you're looking to limit your downside but keep all the upside for yourself, there's a relatively simple options strategy that may interest you. By using call options, you gain when stock prices move up -- but you also set the maximum amount you can lose.

A call option gives you the right to buy 100 shares of stock at a certain price at any time until the option expires. To buy an option, you pay a fixed amount called a premium up front. For instance, on Dec. 1, you could have bought an April call option that would let you buy shares of Chesapeake Energy for $21 between now and mid-April. With shares trading around $21.41 at that time, you would have paid a premium of $1.98 per share, or a total of $198 for that option.

Keep your gains, limit your losses
Now let's fast-forward to mid-April, right before your option expires. Consider two possibilities:

  1. The market rises, and Chesapeake goes to $25.
  2. The market starts falling back, and Chesapeake drops to $17.

If the rally continues, you'll have the right to pay $2,100 for shares worth $2,500, so you'll exercise your option. That gives you an immediate $400 gain, less the $198 you paid for the option, for a net profit of $202. That's not quite as good as the $359 gain you would have had if you'd bought 100 shares outright at $21.41 -- but it's still a sizable profit.

On the other hand, if the rally ends and stocks drop substantially, buying 100 Chesapeake shares outright for $21.41 would've brought you $441 in losses. But with the option, you'd just let it expire rather than paying $21 per share for a stock that's now worth $17. You'd lose the $198 you paid for the option, but you'd avoid losing more than twice as much from owning the stock.

Where options get risky
For some, the appeal of options is the leverage they offer. For about the same $2,141 you'd pay for 100 shares of Chesapeake, you could buy 10 options contracts controlling 1,000 shares. That magnifies your potential gains -- but there's also a big chance you'll lose the entire sum if Chesapeake stock falls between now and when your options expire.

The simple answer is not to use options for leverage. In this example, if you have only $2,141 to invest, just buy a single option contract. You'll put less than 10% of your capital at risk, and it makes it a lot easier to exercise your option and buy shares for the long term -- because you haven't overextended your available cash.
