Year-to-date, you’ve seen software companies get hammered down 24%, the IGV index (iShares Expanded Tech-Software Sector ETF), versus hardware index, let’s say XLK ETF (State Street Technology Select Sector SPDR ETF), down only 3%. There you’re seeing both go radically. That could be, hey, people just want to get in on the action. There’s some speak about many different things. And there’s a little bit of press going on about the big capex spending that has been happening in the industry in general. So, interesting day from that perspective.”::DoordashAmong other movers, shares of DoorDash, up nearly 7% at the close, whiplashed in extended trading to ultimately gain more than 10%.
