The definition of a strong sector is whose return in the given time frame is better than the market. In the last week, the markets closed flat, with Nifty Open (10616) and Close (10605) at the same level.
The seven day ROC of 8.86% makes the CNX PSU sector the best performing last week. I believe the next week’s leaders will be one among the above. Look out for stocks especially in the Banking, Services and Finance sectors.
