It's always fascinating to read stories about average, everyday people who built fortunes by regularly investing small amounts over long periods of time in companies such as American Express
If you worked for these companies, or regularly "trickled" money into them over the years, having amassed a fortune is quite feasible -- American Express, Hewlett-Packard, and ExxonMobil have returned 13.5%, 14.7%, and 17.5% annually over the past three decades, respectively.
But you can also get market-beating returns by buying into great companies at more opportune times -- whenever the stock goes on sale. Rather than regularly investing small, fixed amounts, investors can use the simple method of buying a stock in portions to manage risk and boost returns.
First, find a solid business
Of course, every situation is different, but big returns on investments always come on the backs of fundamentally strong businesses. And if you're confident that you've purchased shares in a great company, why wouldn't you consider buying again, particularly if the stock price is significantly below intrinsic value? Especially in pessimistic markets (like today's), fundamentally strong businesses can be bought for good prices.
For larger, more stable companies, simply buying more shares when the outlook is bleak can be very rewarding. For instance, theme-park operator Walt Disney was hit hard when tourism dropped in the wake of 9/11, and the creative juices in the animated-film division seemed to be drying up. But investors who saw long-term value in the Disney brand and bought on the pessimism are in a happy place today. The stock has nearly doubled in the past five years.
For younger, riskier companies, a strategy of acquiring shares in portions is a smart play. It limits your initial outlay and gives you a chance to buy again if shares experience an unwarranted drop.
For example, look at top retailer Best Buy
Buying more shares of Best Buy near its low at the end of 2000 would have earned you 340% on that new money -- the larger economic conditions had only a temporary impact on the company.
Other companies, such as Cisco Systems
The final caveat with this method is to ensure that you aren't throwing good money at a truly deteriorating company -- hence the importance of understanding the underlying business.
