KNR Construction - with focus on infra, should we go long?

The stock seems to give a descending triangle breakout with a high volume at the start. Currently the volume is less than average and the stock has corrected a bit but has managed to hold on the support line of Rs 302. Is this stock a candidate for long term hold or has it run out of steam?
Should we book the profit or hold (and expect it can withstand the small cap/ mid cap sell pressure which we are seeing since last 7 days)?
It had given a "rounded bottom" trend reversal and have moved 50% from the level of around 210 to Rs. 300.
I am new to charts and would request feedback/ correction to my analysis.
thanks in advance.
