Life Time, Relay Insiders Sell Over $100M Each; Other Execs Buy Dips

Corporate insiders at several high-flying companies, including Life Time Group and Relay Therapeutics, sold large blocks of stock last week, while executives at other firms took advantage of recent price drops to increase their holdings. The transactions, disclosed in regulatory filings on Friday, August 28, 2026, provide a glimpse into how senior leaders and major shareholders view their companies' valuations.

Major Sales Follow Stock Rallies

Significant selling activity was concentrated in companies that have recently experienced strong stock performance. According to Form 4 filings with the Securities and Exchange Commission, the largest transactions included:

• Life Time Group Holdings, Inc. (NYSE:LTH): Three insiders executed substantial sales on August 26. A 10% owner, Green LTF Holdings II LP, along with directors John Kristofer Galashan and John G. Danhakl, each sold shares valued at approximately $126.1 million. The sales were made at a price of $43.80 per share after the stock had gained 56% over the past year.
• Relay Therapeutics, Inc. (NASDAQ:RLAY): SVF Pauling (Cayman) Ltd, a 10% owner, sold 6,000,000 shares for a total of approximately $116.4 million on August 25. The sale, at $19.40 per share, followed a remarkable 426% surge in the company's stock price over the last year.
• Snowflake Inc. (NASDAQ:SNOW): Director Benoit Dageville sold 50,000 shares for a total of $15.47 million on August 26. The sale was conducted at $309.44 per share under a pre-arranged 10b5-1 trading plan adopted in April 2026.

Executives Purchase Shares Amid Weakness

In contrast, several insiders made significant purchases in companies whose stocks have recently underperformed. These buys can sometimes be interpreted by investors as a signal of confidence in a company's future prospects.

Notable purchases included a director and 10% owner of Optimum Communications, Inc. (NASDAQ:OPTU), Neil S. Subin, who acquired $2.45 million worth of stock through multiple transactions between late July and August 25. The purchases were made as the stock traded down 56% over the past year.

Similarly, a director at REGENXBIO Inc. (NASDAQ:RGNX), Gregory Austin Ciongoli, bought common stock totaling $949,381 over two days in late August. The acquisitions occurred while the stock was down approximately 13% for the week.

Other smaller but notable buys were seen at Battalion Oil Corp (NASDAQ:BATL) and United States Antimony Corp (UAMY), where directors and a CEO purchased shares in their respective companies, both of which have seen significant stock price declines in the last six months.

What This Means for Investors

Insider trading activity is closely monitored by investors for potential clues about a company's financial health and future direction. Substantial open-market purchases by top executives are often viewed as a bullish indicator, suggesting that those with the most information believe the stock is undervalued.

Conversely, insider sales are not always a bearish signal. Executives may sell shares for a variety of reasons unrelated to company performance, such as for personal financial planning, tax purposes, or portfolio diversification. The use of pre-scheduled 10b5-1 trading plans, as seen with the Snowflake sale, is a common way for insiders to sell shares over time without being accused of trading on non-public information. Investors typically weigh this activity alongside other fundamental analysis.
