In a market desperate for good news, even a smidgen is grabbed with both hands. After the hike in petrol prices, it was taken for granted that a much-pilloried government would increase diesel prices, too, as a show of decisiveness. This expectation naturally filtered into the stock prices of state-owned oil companies. Investor hope was particularly high on state-run monolith Oil & Natural Gas Corporation (ONGC) with the stock rallying 15% from its June low of Rs.248. Since then the elation has subsided, as the talk of a substantial hike in diesel prices has remained just that — talk.
