Why Synaptics, iQiyi, and Savara Jumped Today

Friday was fairly quiet on Wall Street, with most major benchmarks starting the session in the red but gradually climbing to end with modest gains. Some nervousness about the beginning of the G-7 summit in Quebec City today weighed on market sentiment as the day began, but fairly cordial-looking photo-ops at least allayed the worst fears of the most anxious investors that the meeting among key U.

S. allies would turn into a downright hostile trade battle. Some individual stocks also enjoyed outsize gains thanks to good news. Synaptics (NASDAQ: SYNA), iQiyi (NASDAQ: IQ), and Savara (NASDAQ: SVRA)were among the best performers on the day. Here's why they did so well.
