Given inflationary pressures, Coal India will have to raise wages. This is due in July. In FY11, wage costs accounted for over 50% of total expenditure.Assuming a conservative average hike of 15%, operating margins can then erode by 600 basis points. The company faced a similar problem last year and had to reduce its manpower by 13,000.
Coal India's stock price rose 30% in the last three months. After the announcement of March 2011 quarter results, the stock price vaulted 4% to Rs390. This price factors in all the positives leaving little room for further upside.
