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 such as Citigroup
If you worked for these companies, and/or regularly "trickled" money into them over the years, this is quite feasible -- Citigroup, GE, and Wal-Mart have returned 13.1%, 13%, and 15.6% annually over the past two 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 large, stable companies, buying more shares when the outlook for them is bleak can be rewarding. For instance, buying more Altria
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 Motley Fool Stock Advisor recommendation Mobile Mini
When demand for portable units dropped with the slowing economy, margins began to shrink, and investors poured out of Mobile Mini stock. But the fundamental business operations remained intact. Money invested when the outlook was bleakest is now up more than 280% -- even with the return of another poor economic outlook and a share price well off its high two years ago. The larger economic conditions had only a temporary impact on Mobile Mini's solid business model before, and recent turmoil once again gives investors a cheaper price to consider.
Other companies, such as NVIDIA
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.
