Deep Tide TechFlow news: On July 29, according to the UK’s Financial Times, AI concept stocks have continued to fall recently. Wall Street banks have asked some hedge funds with concentrated positions and higher leverage to add collateral to maintain their existing financing levels. The Nasdaq 100 index, at one point, fell 10% from its early-June peak, while the Philadelphia Semiconductor Index has dropped by about 25% since late June. Against the backdrop of sharp declines in related individual stocks, long–short and multi-strategy hedge funds recorded notable drawdowns in a single day, reflecting that crowded AI trading and leverage risks are accelerating in their exposure.
