Wall Street futures dip as valuation concerns persist

U.S. stock-index futures declined today amid growing concern over stretched valuations, particularly in technology and semiconductor stocks, after global markets saw sharp moves. Investors pulled back from growth-heavy casts and shifted toward defensives and safe-haven assets such as gold and Treasuries. Industry analysts said the absence of a clear trigger, other than valuation pressure, is making the market nervous. Many fund managers reported reducing leverage and rotating exposures. The mood points to increased caution ahead of key earnings and economic data over the coming days.
