S&P 500 futures were essentially unchanged on Monday night after the index posted a second consecutive loss, dragged down by a sell‑off in technology shares. While the S&P 500 slipped 0.07% and the Nasdaq fell 0.51%, the Dow added about 0.3%, briefly pushing past 50,000 points.

Call premiums on out‑of‑the‑money Nasdaq‑100 contracts have risen to a 52‑week high, and the index has set a new record, up more than 16% year‑to‑date, propelled by a semiconductor rally that now comprises nearly 20% of the S&P 500. This concentration has driven options traders toward single‑stock bets, widening the Cboe S&P 500 Constituent Volatility Index relative to the VIX, while Robinhood data shows retail investors heavily buying tech giants such as Nvidia, Tesla, Micron, AMD and Microsoft and shorting laggards like Costco, UnitedHealth and Alibaba.
