Hello, and thank you for your comment,
Yes, analysis most certainly can be too much and analysis paralysis is a large problem for research analysts, portfolio managers, and other investment professionals. I agree with you that analysis paralysis can be an indication of a lack of insight. However, I have seen many examples of analysis paralysis in my career and generally they have to do with the anxiety associated with taking on large amounts of responsibility. I say in my book The Intuitive Investor that the difference between being an analyst and a portfolio manager is the difference between aiming the gun and firing it.
As for your question at the end of your comment...I am unsure as to what you are trying to ask. If you feel like it please provide clarification and I am happy to attempt to answer your question.
With smiles,
Jason
