On this episode of Stock Movers:

- Flower Foods (FLO) slid in extended trading after the maker of Wonder Bread cut its adjusted earnings per share forecast for the full year.

- Ross Stores (ROST) raised its annual profit outlook for a second time this year, signaling that the discount retailer’s momentum is holding up. The California-based company now expects full-year earnings of $8.61 to $8.77 a share, it said in a statement Thursday, up from $7.50 to $7.74 previously and ahead of Wall Street’s estimates.

- Moderna (MRNA) shares tumbled 24%, the worst ever daily slide, one day after the drugmaker’s record 177% surge that stemmed from a clinical trial win.
