Pro Talks: Investment strategy with Nicholas Colas

In an exclusive strategy session only for Pro subscribers, Nicholas Colas, chief market strategist at Convergex Group, revealed some of the lesser-known metrics he uses to successfully value individual stocks and the overall market.

Looking at data available to anyone, such as income tax receipts, can often give astute investors a better read of the economy than the official monthly reports everyone else watches, according to the Wall Street veteran.

During his conversation with CNBC's Mike Santoli, Colas also discusses value versus growth strategies, dividend stocks and how to invest when easy money from central banks seems to be driving all the action.
