Buybacks no panacea
IT majors should find better ways to use the cash

The decision of Tata Consultancy Services (TCS) to buy back its shares will be welcomed by a section of shareholders who can exit at a profit. At least two of TCS’ peers, Infosys and Wipro, have also hinted that a buyback decision could come in the near future. In general, as a tool to reward shareholders, buybacks seem to be gaining currency after last year’s additional tax on dividends above a threshold. But the record shows buybacks are not efficient in lifting share prices over the medium- and long-terms and can, at best, provide a short-term gain. For example, the top 10 buybacks in India show that shares gained an average of 1.5 per cent a year after the repurchases ended. Returns have been slightly better at eight per cent and six per cent, respectively, one year after the buyback’s announcement and commencement. In the case of the top 20 buybacks by size, average returns one year after their announcement, commencement, and end are 7.4 per cent, 8.5 per cent, and 4.3 per cent, respectively.
