On assuming the chart of Bharti Airtel, it seems that the stock is near its multi months upward resisting trend line which is placed near 390 levels. A closing above the trend line on daily basis may blast the stock on upper levels. However, buying may be advised after breaching the trend line resistance, till then wait and watch whether the stock may be corrected further or take the breakout from these levels. Buying volumes looking decent may be decisive .... wait for the final confirmation before go to a trade.
