Tech Stocks Tumble: AMD and Super Micro's Gloomy Outlook

Wall Street is bracing for a negative start as tech stocks are expected to drive declines following disappointing updates from the sector. S&P 500 futures are down 0.5%, and Nasdaq 100 contracts are losing 0.8%.
Advanced Micro Devices shares are down 6% in premarket trading after providing a lukewarm revenue forecast for the current period. Super Micro Computer shares also drop 9% due to concerns over capital needs despite an earnings beat.
With most European markets closed for a holiday, the focus remains on the tech sector's performance and its impact on the overall market direction.
