We recommend a buy in the stock of PBA Infrastructure from a short-term horizon. It is seen from the charts of the stock that it has been on a long-term sideways consolidation in a broad range between Rs 60 and Rs 100 from August 2009. Within this broad consolidation, the stock was on a medium-term downtrend from its upper boundary of Rs 100 to its lower boundary of Rs 60 between mid-October 2010 and early December. However, the stock changed direction taking support from its significant long-term support level at Rs 60 and also triggered by the positive divergence displayed in the daily relative strength index and price rate of change indicator. On December 29, the stock surged 10.5 per cent accompanied with heavy volume penetrating its medium-term down trendline and 21-day moving average. Moreover, an immediate resistance at Rs 66 is also breached. The daily relative strength index is rising in the neutral region towards the bullish zone and weekly RSI has entered in the neutral region from the bearish zone. Daily moving average convergence divergence oscillator has signalled a buy. We are bullish on the stock from a short-term perspective. We expect it to move higher until it hits our price target of Rs 72 or Rs 74 in the upcoming trading sessions. Traders with short-term perspective can consider buying the stock with stop-loss at Rs 67.
