Why Twitter, Gap, and Macy's Jumped Today

The stock market was fairly quiet on Tuesday, with major benchmarks staying relatively close to where they began the session. Investors largely seemed to take a break as they wait for further guidance on key issues, including the geopolitical situations with North Korea and key U.S. trading allies, who are still reeling from tariff threats.

In addition, the meeting of the Federal Reserve later this month should shed some light on the central bank's future course of monetary policy. Even in a calm market, some stocks managed to post substantial gains. Twitter (NYSE: TWTR), Gap (NYSE: GPS), and Macy's (NYSE: M)were among the best performers on the day. Here's why they did so well.
