When it comes to investing in micro-cap stocks, most investors have one thing to say: “No thanks,” often for good reason. Many, many micro-cap stocks are merely the withered remains of once high-flying companies with little hope of rising again. Others are enterprises that have never been and will never be profitable and will continue to burn investor capital until they are delisted. Others are outright scams or subject to rumor-spreading and manipulation. Might as well shovel cash into the fireplace, right? The truth is that profitable micro-caps with great growth potential do exist, but it takes some research to find them.

Luckily, I took care of that and found AeroCentury Corp. (ACY). I believe this stock has great potential for great capital gains in 2009 and beyond. At a market cap of only $16 million, AeroCentury has room to grow for decades to come before the law of large numbers begin to slow it down. Let me elaborate a little.
