There is a saying in Wall Street that says, one should buy when there is 'Blood on the Streets'. Investor sentiments can play a big role in market turning points. Marc Faber thinks the markets have a good chance to disappoint bullish investors.
"I have maintained that the January 26th high for the S&P up 2,872 was like a mirror image of the low on March 6th, 2009 when the S&P was at 666. At that time, everybody was bearish and leading strategy and I don't want to name who, but they were predicting for the S&P to fall to 400. And what happened is that, because sentiment was so negative, and the market was so oversold, the market turned around and actually on very poor earnings, started to go up. And now, we have, in January, a high, when everybody felt that the market would go higher and what then happened is that on good earnings, stocks didn't move up, but started to go down.
So, I think we are in a situation where it is likely, it's not yet a hundred percent sure, in order to get a clearer picture, if a major bear market has started, we would have to make a low below the February low, but that hasn't happened yet. But looking at the market and the market action and the momentum and the number of stock that are actually making new lows, I'd say there is a fair probability that the market will disappoint point very badly."
