However, insider buying is also on the rise. For instance, executives and board members at Eli Lilly recently purchased millions in company shares after a market decline due to underwhelming drug trial data on the firm’s weight loss pill. CEO David Ricks bought over $1 million in Eli Lilly shares on his own. [1]
Tracking insider sales can provide valuable insights into potential market performance. Paul Holmes, a stock market analyst at BrokerListings.com, notes that heavy insider trading activity can indicate a shift in company sentiment. Large insider buying might suggest that executives believe shares are undervalued or that growth is coming that isn't currently discounted in the price. Conversely, insider selling can indicate pessimism about the company’s strategy or future, or simply profit-taking. [1]
Olivier Wagner, a veteran trader and CEO at 1040 Abroad, cautions that insider selling might not always reflect the company's performance. Personal diversification or tax planning could be the reason behind such trades. However, if insider selling occurs during a time of financial uncertainty or a bad earnings announcement, it could be a pointer to internal problems. [1]
David Miller, co-founder and senior portfolio manager at Catalyst Funds, highlights that excessive insider buying is a strong signal that executives have an insight based on their knowledge of their company operations and their industry that their stock is substantially undervalued and likely to appreciate in the near future. [1]
While tracking insider trades can be beneficial, conventional wisdom suggests that regular investors should not necessarily follow insider trading trends to the letter. Many of the best-performing stocks over the last decade have had consistent insider selling, often due to executives looking to diversify their wealth. However, it never hurts to study up on what key company insiders are doing. Investors can start by visiting SEC.gov, insidermonkey.com, or insiderscore.com for insider buying and selling data. [1]
In conclusion, insider trading activity can provide valuable insights into corporate sentiment and potential market performance. However, investors should approach this information with a critical eye, considering the context and motivations behind the trades.

Implied volatility and options positioning are significantly influencing daily equity market movements, leading to the October 20 rally, despite a lack of fundamental justification. This suggests that investors are increasingly focused on short-term trading strategies rather than long-term investment decisions. As a result, volatility is outsmarting both bulls and bears, and investors must adapt to this new market dynamic.
In recent months, significant insider trading activity has drawn substantial interest from investors, particularly in major Fortune 500 companies such as Nvidia, Tesla, and Fox Corp. [1] Insider sales for these companies have been particularly noteworthy, with Nvidia insiders selling over $1 billion worth of stock from June 2024 to June 2025, including $42 million by CEO Jensen Huang. Fox insiders have conducted $1.165 billion in trades, with more "sells" than "buys," while Tesla insiders have engaged in just under $1 billion in trades, also with a higher number of "sells."However, insider buying is also on the rise. For instance, executives and board members at Eli Lilly recently purchased millions in company shares after a market decline due to underwhelming drug trial data on the firm’s weight loss pill.
