We recently published a list of 12 Stocks with Heavy Insider Buying in 2025. In this article, we are going to take a look at where Biohaven Ltd. (NYSE:BHVN) stands against other stocks with heavy insider buying in 2025.

Insider trading is often seen as an important indicator of management’s confidence in their company’s future. For decades, top investors and analysts have endorsed this idea, arguing that insiders purchase shares of their own companies for one primary reason – if they firmly believe the stock price will increase significantly and grow the value of their investment. This idea stems from the fact that insiders, such as high ranked executives and directors, possess confidential information and data that helps them draw insights into the company’s outlook and growth trajectory well before outside investors are able to. As a result, empirical research on the topic tends to agree that insider buying coincides with troughs in stock prices, and vice versa, insider selling coincides with peak valuations.

The US stock market has experienced two years of explosive growth, following the 2022 bear market fueled by rising inflation and interest rates. For most of 2023, the stock market appreciation was primarily driven by a small subset of companies fueled by AI-related tailwinds, which led to rising concentration levels, all while on an equal-weighted basis, the performance was staying flat. The following year brought a broader acceleration in growth, with many other sectors catching up and driving a new all-time high into early 2025. We can now firmly say that the bear market of 2023-2024 has been broad, leading to apparently expensive valuations across the entire market. It is certainly not easy to be an investor in the US market right now, as peak valuations make most of the companies appear expensive, all while new threats and risks loom from all directions.

The new US administration has brought a major change in trajectory, something which hasn’t been seen in decades. Many of their new policies are a short-term (at least) threat to several industries and sectors, ranging from Medicare/Medicaid reimbursements and ending with Government consulting, engineering, and technology contractors. A more recent development, which arises as a result of the new Government policies, is a potential slowdown in commercial and residential construction – the freshly imposed tariffs are a major headwind for builders, as they make building materials significantly more expensive, all while the heightened scrutiny on immigration can potentially cause labor shortages in this field, which again makes building more expensive. The key takeaway is that plenty of new risks arise every day, which, coupled with still near peak valuations, makes it difficult for investors to decide which stocks to invest in.

With that being said, we believe insider buying could provide unique insights into what more informed investors (management itself) believe will happen with the stock price of their company. Sudden developments often bring overreactions from investors, which create opportunities for more informed investors to act. In this context, closely watching insider buying could provide a strong signal that the market overreacted to some negative developments. Also, we believe that the larger the amount of stock an insider is buying, the stronger the insider’s conviction in the future of the company. That’s why we decided to particularly track companies that have shown heavy insider buying in the last couple of months.

Our Methodology
