Nasdaq Climbs 2% to Near Record as Meta Jumps 11%, AMD Gains 8%

The Nasdaq Composite rose 2% to near a record high Sept. 21, 2026, Yahoo Finance reported. Meta jumped 11% and AMD gained 8%. For savers and 401(k) holders, such concentrated tech gains lift index returns but leave portfolios exposed if those few names stall. I see breadth, not just price, as the test.
