Why Arm Holdings Stock Fell on Tuesday

Arm Holdings stock fell 3.3-5.1% on Tuesday following a regulatory filing revealing CFO Jason Child sold 10,400 shares worth $2.65 million. However, the sale was part of a pre-planned Rule 10b5-1 trading plan and represented only a small portion of his $39.6 million stake. The stock's rich valuation at 239x earnings contributed to the volatility.
