Semiconductor stocks surge over 50% in 25 days, matching dot-com bubble peak speed.

The PHLX Semiconductor Index has risen more than 50% over the past 25 days, marking its strongest performance since March 9, 2000, just before the dot-com bubble peaked. This rapid increase recalls the bubble era when the Nasdaq Composite reached a high before losing 80% of its value over three years. Investors should be cautious as history shows such rapid gains can precede significant downturns. The market's next moves remain uncertain amid this rally.
