Investors have made big bets on tech stocks. Why one strategist just downgraded the sector.

Investors have piled into tech stocks for years, but recent trends show slowing inflows as prices have become less attractive. A key strategist has decided to downgrade the sector due to these deteriorating valuations, signaling potential risks ahead. This move is significant as it reflects broader concerns about the sustainability of tech's outsized gains and could prompt other investors to reassess their portfolios. The decision underscores a shift in market sentiment and the importance of keeping an eye on valuation metrics.
