For most investors, option investing leads to permanent capital losses. But there is one type of equity optionthat, when used and understood carefully, can offer fantastic potential many times the return.

Invest for the long term
LEAPS -- which stands for Long-Term Equity Anticipation Securities -- is just a fancy name for long-term stock options. LEAPS usually extend as far as two-and-a-half years into the future, and they operate just like traditional options. They give you the right to buy (we'll stick to call options) a certain stock at a certain price within a certain time.

Most option investors incur losses not because they've incorrectly analyzed the bull or bear thesis of a business, but rather because the option expires before the stock price had time to follow the business performance. And although most investors won't be able to buy really long-term options -- like the ones Berkshire Hathaway (NYSE: BRK-A) (NYSE: BRK-B) wrote on stock indexes, with expirations 10 years or more in the future -- LEAPS have long enough lifespans to get you past a lot of the noise of short-term market fluctuations.

Remember: We are investing
If you look for good businesses and try to leverage your returns by investing in long-term options, you are approaching the process backwards. Choosing to invest in long-term options should come as a byproduct of your research efforts.

Before you investigate LEAPS, wait for an unusual investment opportunity to grab your attention. After you find a business that offers a compelling investment opportunity, you can determine whether an investment in a long-term option would benefit you.

The long time frame LEAPS provide investors also offers adequate time for the investment to play out. To use long-term options wisely and profitably, two conditions in the underlying business should exist:

A compelling equity investment
In the recent rally, anyone who bought LEAPS on risky stocks such as Las Vegas Sands (NYSE: LVS), Citigroup (NYSE: C), and Ford Motor (NYSE: F) has hit the jackpot. But typically, you wouldn't buy long-term options on severely beaten-down businesses, simply because they are selling near multi-year lows and you have a gut feeling the shares will somehow find their way back up. To invest in long-term options prudently, investors need to put in the same disciplined research as they do with equity investing.

Similarly, you want to avoid the long-term options of businesses that aren't trading at significant discounts -- less than 50% to 75% -- of intrinsic value. The reason is simple. Investing in a long-term option of a $30 stock that you feel will be worth $40 to $50 in two years will not offer a return that would compensate for the risk.

Case study: Wells Fargo LEAPS
An excellent example of a LEAP candidate was described in You Can Be a Stock Market Geniusby Joel Greenblatt. During late 1992 and early 1993, Wells Fargo (NYSE: WFC) was trading for around $77 a share. At that time, California was going through one of its worst real estate recessions. Wells Fargo had a huge concentration of commercial real estate loans, more than its largest competitor at the time, Bank of America (NYSE: BAC).

At the then-current share price, Wells earned nearly $36 a share in pre-tax profits, but the earnings were eaten up by heavy loan loss provisions that seemed overly conservative. During typical real estate conditions, loss provisions were about $6 a share. Assuming a 40% tax rate, the $30 in earnings would be about $18 a share. At a very fair multiple of 10, this meant Wells Fargo could be trading at $180.

Conditions like these make an investment in a long-term option very favorable. The discount to assessed intrinsic value was very high and made an excellent investment. Continued...
