The "Musk premium" swings both ways: SpaceX (SPCX.US) surges and then retreats in its first month after IPO, while Tesla (TSLA.US) adopts a defensive-offensive strategy.

This giant conglomerate, controlled by Elon Musk and integrating aerospace, telecommunications, AI, and social media, has seen its stock price plummet by over 35% from the closing high of $225.64 set on June 16, just one month after going public. On July 9, the price even hit a historic low of $145.20 during trading. As of the July 9 close, SpaceX stood at $149.29, marking two consecutive days below the IPO opening price of $150.
