The Atara Biotherapeutics stock holds a buy signal from the short-term Moving Average; at the same time, however, the long-term average holds a general sell signal. Since the longterm average is above the short-term average there is a general sell signal in the stock giving a more negative forecast for the stock. On further gains, the stock will meet resistance from the long-term Moving Average at $14.16. On a fall, the stock will find some support from the short-term average at $12.77.

In technical terms, this is called divergence and may be an early warning. In some cases, increasing volume on falling prices may be considered positive, but that is mainly in typical "sell-offs".
