Michael Cintolo of The Cabot Market Letter — which has an excellent track record over the past decade — says that the stock market for the moment remains range-bound, but that investors should stay bullish.

“The market continues to trade in a very tight range, though stocks have been ‘leaning higher’ in recent days, a possible sign that the buyers want to push the indexes to new highs before year-end,” Cintolo writes in Cabot’s Top Ten Report. “Whatever the market’s exact path, our main thoughts are unchanged: First, the overall trend is up, but second, the environment has become very choppy.”

Cintolo recommends that investors “remain bullish, but try to buy on weakness or after a few weeks of tight action.”
