Good old Louis R. He was not always a bull, but the show did have a bullish inclination. Marty Zweig said to buy tech stocks in Jan 2001, as they had lost half their value by then and looked good. He was wrong. Abby "permabull" Cohen was super bullish and said to be 100% invested, just before the market lost 35% of its value.
I can see how so many advisors see 1575 reached again, and i would not be surprised to see 1500 plus by march. But investing at the end of a bull has only lost me money in the past. Sometimes a lot of money, as an event that will knock the market down 20% in a few days is going to happen soon, and when it does the bulls are hurt fast.
Soon could be the spring, btw.
