AT&T (T) is a long-time household name that's synonymous with telephones and communications. The charts of T have not fared so well in recent years. Let's see what is going on now ahead of their earnings numbers next week on January 25th.
In this daily bar chart of T, below, I can see a top pattern in May/June/July followed by a decline into October. Prices rebounded into November but have made another potential top pattern in December and January. Prices are testing the 50-day and 200-day moving average lines.
The daily On-Balance-Volume (OBV) has moved up from a low in October but has "rolled over" in recent weeks. The Moving Average Convergence Divergence (MACD) oscillator has just made a lower high when prices made a slightly higher high - creating a bearish divergence.
