Why does the Chief Economic Advisor feel that the stock prices are likely to be corrected?

1 cannot be because it is a consequence of correction in stock prices. 2 cannot be because “‘sudden stall’ induced by sharp corrections to elevated stock prices.” This means sharp corrections have resulted in sudden stall and not vice versa 3 is out of the context. 4 is correct as it is said in the passage “Among the concerns the CEA has flagged is one relating to what the Survey calls “a classic emerging market ‘sudden stall’ induced by sharp corrections to elevated stock prices.” With Indian stock indices continuing to soar to new highs on an almost daily basis, the Survey warns against “sanguineness about its sustainability”.
