However, according to the GuruFocus Value, which is an intrinsic value estimate based on historical multiples, a GuruFocus adjustment factor, and future business performance estimates, the stock is modestly undervalued. With a price of $47.38 and a GuruFocus Value of $62.25, Prothena Corp PLC has a price-to-GF-Value ratio of 0.76.

This discrepancy between the stock's current price and its GF Value could suggest that, despite the recent insider sell, the stock may still present a good investment opportunity. However, potential investors should also consider the insider's trading activities and the overall trend of insider sells at the company when making their decision.

In conclusion, while the insider's recent sell of Prothena Corp PLC shares may raise some concerns, the stock's modest undervaluation according to the GF Value could still make it an attractive investment. As always, potential investors should conduct their own thorough research before making any investment decisions.
