The AI/technology investment theme continues to be a focal point today, particularly as the Magnificent 7 stocks grapple with significant fluctuations.

With Nvidia (NVDA) down 3.4% at $174.19 and Microsoft (MSFT) showing marginal gains at $414.19, the outlook for enterprise software remains bleak as it struggles under a 23.0% decline over the past 20 days.
