Indian stock indices - Sensex and Nifty - yet again touched their all-time highs Wednesday. The indices were above 1 percent higher at the time of writing this report. Sensex tasted its high at 63,601.71 points and Nifty at 18,887.60 points. Indian stock indices, which have been buoyant over the past several sessions, touched their all-time highs last Wednesday too. The rise in domestic stocks is in tune with the global market rally and firm domestic macro fundamentals. Strong fundamentals including a firm GDP outlook, moderate inflation, and strong purchases by foreign investors saw the markets trading in the green. The inflation in the US and India is moderating, but what is to be seen going ahead is whether this trend is sustainable.
