The current health of the stock is already factored in the price. If one believes that is not the case, then he may remain invested.
Now, if we expect (hope) things to further improve, then it is the thing of the future, which may or may not unfold as expected.
Furthermore, when the bear markets start PSUs get hammered first.
NPA may get worse, its a strong possibility. Any growth in the near future will be negated till this NPA issue gets cleared.
Therefore, I think correction is now on the cards. If you look at the price action, you will see that REC has not been able to make a fresh high since 2010, at least not decisively. It will take sustained good numbers to breakout its 52W high.
