Coca-Cola (KO) shares are due to report earnings tomorrow, but is the recent rally enough to keep the momentum going? Ben Watson says while the short-term chart shows some strong bullish momentum, there are signs of a slowdown, particularly with momentum indicators turning negative. Looking at the longer-term chart, Ben notes that KO has been in a declining pattern over the past 6-7 months, but a recent break above the 50-day moving average could be a bullish sign.
