Yeo Mui Sung sold 19,143 shares at $71.98, a price approximately 0.2% above the current market price of $71.77 and near the 52-week high of $74.87. The stock has gained 24.7% over the past 30 days and 103.4% over the past 90 days, placing the transaction in a strong uptrend. The sale reduced the director's holdings by 19.6%, a material reduction in personal stake. The company is trading at an elevated P/E of 17942.50, though this appears driven by depressed earnings rather than valuation exuberance, with net income at $16.8M on $199.6M in quarterly revenue and annual revenue declining 7.4% year-over-year. The transaction occurs after significant recent gains and does not appear driven by a scheduled 10b5-1 plan.
