The Invesco QQQ Trust (QQQ), now 27 years old, recorded a historic trading volume of approximately $80 billion in a single session, while leveraged semiconductor ETF SOXL also hit a record with $25 billion traded. The unprecedented volume signals intense institutional repositioning during what market observers described as a "five alarm fire" selloff. ETF trading volume is widely regarded as a fear gauge, as large institutional traders typically use these vehicles to adjust portfolio allocations during periods of market stress. The surge in activity suggests significant hedging and rebalancing was underway across tech and semiconductor positions.
