Some excerpts from the article
In his new book, Chasing Stars: The Myth of Talent and the Portability of Performance, Groysberg studies a group of professionals renowned for the portability of their talent — Wall Street research analysts. Analysts are a hybrid of researchers and pundits; they study public companies and write recommendations about whether to buy or sell their stocks.
So what happened? Groysberg reports, “Star equity analysts who switched employers paid a high price for jumping ship. Overall, their job performance plunged sharply and continued to suffer for at least five years after moving to a new firm.” Worse, switching firms doubled the chance that an analyst would fall off the rankings entirely (32% versus 16%).
