PNB has reacted from above 700 levels, the previous resistances with "OB" readings but no sell signals. It continues to be a buy on dips. If the last few actions is to be taken as a "running correction", then clearing the 700 mark decisively will take it to much higher levels.
"SBI" and some other PSU banks have given a breakout from a 2 month consolidation pattern. Sectoral play may come into play here and PNB is an outperformer in the banking space.
50-DMA(Brown) may offer supports @ 665. If macd turns up in the next 2 days time, this negative divergence may get negated.
