AT&T (T) has been trading in a sideways manner since 2016. But within this sideways market, there has been sharp bull runs and sharp bear runs. Let's take a look at the chart.AT&T (T) Daily Chart(click to enlarge)Support:- The daily chart shows that price bounced off a key support around 36 in July.- The sharp rebound shows that the market is still sideways with a prevailing uptrend - meaning it did not open a bearish outlook.- Indeed, a V-shape reversal we saw in the past month is indicative of a bullish reversal. Resistance:- However, price was stuck under the 40 handle, and the 200-day simple moving average (SMA). - Note after a few weeks of decline, T is trading around 37.50. - The RSI is around 40, where it should turn up if the bullish push in July is to maintain the bullish momentum.- So, I think the area around 37 should be monitored for support. - There is upside back towards 40, with a more aggressive target around 42. The highs have been falling, so we should probably be conservative with bullish expectations.
