Shares in the tech sector are up 35%, with Nvidia and Meta leading the way, but valuations are above the market average, raising concerns.

Companies in the technology sector have averaged a 35% increase over the past three months, with Nvidia and Meta up 52% and 41%. Although Nvidia's capitalization has reached nearly $4.2 trillion, valuations are considerably higher than the market average. Experts point out that while earnings are solid, growth in share values could be limited in the future. Cost challenges and trade uncertainty are risks for the tech sector in the second half of the year.
