Stocks Rose in January, but Investors May Not Be So Lucky in February

Stocks rose in January, but investors may not have the same luck in February. The Dow Jones Industrial Average rose 0.5% during the month, the S&P 500 gained 1.8%, while the tech-heavy Nasdaq added 4.3%. The best-performing S&P 500 sectors for the month were materials, information technology and consumer discretionary.

"The leaders in the market [such as FANG stocks] have started to roll over in the past couple of sessions," said TheStreet's Brian Sozzi. FANG stocks include Facebook (FB) - Get Report , Amazon (AMZN) - Get Report , Netflix (NFLX) - Get Report , and Alphabet (GOOGL) - Get Report .

Sozzi also pointed to building materials stocks such as Eagle Materials (EXP) - Get Report . "These stocks have led the market over the past six months, and they're starting to roll over. And that's a concern."
