if the domain name can increase their brand popularity, there's a chance and correlated with sales! it mean more profit, it mean stock price increase! Good domain, can help marketing department! because good domain can win the game! easy to remember, save PPC bugdget, save ads, save money! more profit!
my point is, for long term yes it can increase stock price! because for some reason domain name make everything more easier! but for short term no!
