The company's portfolio includes a range of products aimed at addressing the unmet medical needs of patients with conditions such as Parkinson's disease, tardive dyskinesia, and endometriosis.

Analysis of Insider Buy/Sell and the Relationship with the Stock Price

Insider transactions can provide valuable insights into a company's health and future prospects. Over the past year, Eiry Roberts has sold a total of 43,976 shares and has not made any purchases. This pattern of insider selling could be interpreted in various ways. While some may view it as a lack of confidence in the company's future growth, it is also common for insiders to sell shares for personal financial planning or diversification reasons.

The relationship between insider sells and the stock price of Neurocrine Biosciences Inc is complex. While the company's stock has been trading at $120.03, giving it a market cap of $11.522 billion, the insider selling activity does not seem to have had a direct negative impact on the stock price. In fact, the stock is currently considered modestly undervalued with a price-to-GF-Value ratio of 0.81, indicating potential for upside.

The price-earnings ratio of Neurocrine Biosciences Inc stands at 63.05, which is higher than the industry median of 23.54 but lower than the company's historical median price-earnings ratio. This suggests that while the stock may be trading at a premium compared to its peers, it is still below its own historical valuation levels.

It is important to consider the broader context of the insider selling activity. The insider transaction history for Neurocrine Biosciences Inc shows zero insider buys and 48 insider sells over the past year. This trend could signal that insiders, including Eiry Roberts, may believe that the stock is currently valued fairly or that they are taking profits after a period of stock price appreciation.

This valuation suggests that despite the insider selling activity, the market may not be fully recognizing the potential of Neurocrine Biosciences Inc's business. Investors might see the current price as an opportunity to invest in a company that is poised for future growth, especially considering the company's strong pipeline and focus on high-need therapeutic areas.


The recent insider sell by Eiry Roberts, the Chief Medical Officer of Neurocrine Biosciences Inc, is a significant event that warrants attention. While the reasons behind the sell are not publicly known, the overall insider selling trend and the current valuation metrics provide a mixed picture. The modestly undervalued status of the stock, according to the GF Value, suggests that there may be an opportunity for investors. As always, it is crucial for investors to conduct their own due diligence and consider the broader market conditions, the company's fundamentals, and their investment strategy before making any decisions.
