From a Blog I follow : TATA COMM is within a rising trend, which indicates a continued growth. It also gave positive signal from a inverse head and shoulders formation at the break up through the resistance at 526. Further rise to 831 or more is signaled. The stock has broken a resistance level in the short term and given a positive signal for the short-term trading range. The stock has marginally broken up through the resistance at rupee 537. An established break predicts a further rise. Positive volume balance, i.e. high volume in days of rising prices and low volume in days of falling prices, strengthens the stock in the short term. The stock is overall assessed as technically positive for the medium long term.
