A basket of 50 stocks heavily favored by retail investors has dropped 13% so far in July, signaling a sharp deterioration in the momentum trade that has defined much of the recent bull market.

The sell-off, which includes prominent names such as Robinhood Markets and Marvell Technology, is inflicting significant losses on amateur traders who have been the staunchest supporters of high-growth equity strategies.

The decline in these retail-favorite names is part of a wider repricing across momentum-driven equities.

According to Handelsavisen analysis, momentum stocks are currently enduring their fourth-worst July performance in 22 years.

The selling pressure is being driven largely by a sustained retreat from the so-called Magnificent Seven technology giants, which have seen their valuations compress as investor sentiment shifts away from high-flying growth names.

This retail-focused rout coincides with severe losses for quantitative hedge funds, which are facing their most significant trading downturn of 2026.
