Stocks are back to positive on the year. January's better-than-expected jobs report is the latest positive data for bulls to hang their hats on but the U.S. markets have never rallied for seven years in a row. Scott Wren, senior global equity strategist at Wells Fargo Investment Institute, says the current market conditions with a growing economy and low inflation are positive catalysts for stocks. Wren says to expect 'investors to become less risk averse as the benefits of low energy prices and inflation flow through the domestic economy.' Wren expects inflation to stay low and deflation isn't a big concern for the U.S. but 'disinflation' is being closely watched by the Fed.
