Investors should pay attention not only to whether but also to why current holdings are undervalued. It is critical to know why you have made an investment and to sell when the reason for owning it no longer applies. Look for investments with catalysts that may assist directly in the realization of underlying value. Give reference to companies having good managements with a personal financial stake in the business. Finally, diversify your holdings and hedge when it is financially attractive to do so.

It necessitates dealing with imperfect information - knowing you will never know everything and that that must not prevent you from acting. It requires a precarious balance between conviction, steadfastness in the face of adversity, and doubt - keeping in mind the possibility that you could be wrong.
