Teradyne Stock Dips 1.92 as 0.27 Billion Volume Ranks 360th Amid CEO Sale and Strong Earnings

On August 14, 2025, Teradyne (NASDAQ:TER) closed with a 1.92% decline, trading at $111.77 as of market close. The stock recorded a daily trading volume of $0.27 billion, a 54.05% drop from the prior day’s activity, ranking it 360th in volume among listed equities. This performance followed mixed investor sentiment despite the company reporting strong Q2 2025 earnings, which exceeded expectations with $652 million in revenue and $0.57 per share in earnings.

A key development influencing Teradyne’s stock was the sale of $58,724 worth of shares by CEO Gregory Stephen Smith on August 12. Executed under a pre-arranged Rule 10b5-1 trading plan, Smith sold 554 shares at $106.00 apiece. Post-transaction, he retained a significant stake of 96,992.995 shares. While insider sales can signal varied investor behavior, this transaction occurred as the stock traded above its fair value estimate, raising questions about short-term positioning amid broader market volatility.

The strategy of buying the top 500 stocks by daily trading volume and holding them for one day from 2022 to 2025 delivered moderate returns. The 1-day return averaged 0.98%, with a total return of 31.52% over 365 days. This approach captured some short-term momentum but faced market fluctuations, achieving a peak 7.02% return in June 2023 and a low of -4.20% in September 2022. Overall, the strategy demonstrated a positive trend despite volatility, aligning with opportunities for traders focused on intraday movements.
