having basically not moved in weeks the last three days are negative but a lack of volume is unconvincing. the stock needs a catalysts to move prices to new highs and continue trending up. rising volatility at the end of an intermediate length trend is a sign that the fundamentals driving the stock higher are already reflected in the stock price and speculators and late-comers are taking over and absorbing stock from early buyers cashing out their profits. if the stock doesn't hold it's 50-day moving average i am a seller of PINS.
