Retail investors are significantly increasing their call option purchases on the "Mag 10" stocks, according to Cboe Global Markets. This group, which includes AMD, Broadcom, and Palantir alongside the Magnificent 7, has seen a surge in retail call option volume, marking the heaviest 10-day stretch since 2021. Notably, 52% of new positions are call buys, compared to just 17% sells, indicating strong bullish sentiment. The Mag 10 stocks, deeply involved in the AI sector, have driven the Magnificent 10 Index (MGTN) up by 22% since March 2026. This surge in retail activity comes ahead of major tech earnings, with Cboe noting the highest levels of retail bullishness since the COVID-19 lockdowns. In response, Cboe plans to expand its product offerings, including A.M.- and P.M.-settled options on the MGTN index, to accommodate nearly 24×5 trading.
