Investinglive analyst Justin Low stated that U.S. stock index futures are currently showing a mixed picture. Yesterday's sharp decline in Wall Street tech stocks continued even after Amazon's earnings report. Large U.S. tech companies are still trying to justify their increased spending on AI infrastructure, but investors are increasingly adopting a "let's see the results" mentality. Notably, U.S. stock index futures rebounded somewhat after falling in Asian trading today, with Microsoft shares rising as much as 1.6% pre-market and Palantir shares rising over 5% pre-market, both stocks having suffered heavy losses in yesterday's trading and for most of this week. However, the latest rebound only provided some relief, as the S&P 500 dipped slightly yesterday, attempting to test its 100-day moving average. The last time this key level was reached was in November of last year, when bargain hunters prevailed. However, if we use the Nasdaq index as a benchmark, tech stocks may fall again this week, thus reconfirming a break below the 100-day moving average—if so, this will inevitably affect the S&P 500 index and may even impact broader risk sentiment on Wall Street.
