Why Flexion Therapeutics Shares Shot 12.8% Higher in July

After the company hosted an investor's day on July 10, shares in Flexion Therapeutics (NASDAQ: FLXN) jumped 12.8% last month, according to S&P Global Market Intelligence.

Flexion Therapeutics doesn't have any medications on the market yet, but that could change later this year when the U.S. Food and Drug Administration issues a go/no-go decision on Zilretta, the company's treatment for chronic knee pain caused by osteoarthritis.
