Luke Thomas, 44, an information technology field manager who lives in Miami, began investing in the U.S. stock market in his early 20s, attracted by the prospect of learning “how to grow a little bit of money into a lot,” he said.
At the time, he put most of his money into a handful of small-cap and over-the-counter stocks. Yet watching the Russell 2000 index of small-cap companies fall more than 60 percent during the 2008-2009 financial crisis scared him into diversifying his portfolio. He now invests in large-cap stocks, real estate, options, and cryptocurrencies such as bitcoin, spreading his risk over several asset classes.
