Nike to introduce $100 sneaker line after shares fell to worst-ever drop. Is it risky?

Nike shares slumped Friday, ending the day down 19.98%, the biggest one-day percentage drop in the stock’s history.

Nike will roll out new $100-and-under sneakers in countries around the world, its chief financial officer said Thursday, as the sportswear giant tweaks its product lineup in a plan aimed at getting sales back on track.
