“Investor sentiment has turned increasingly pessimistic amid the technology selloff and sharp rotation, but the broader market is telling a different story,” Mark Hackett at Nationwide told Bloomberg in an interview. “Rather than the start of a major downturn, this looks more like a period of consolidation beneath the surface.”
