"Steep rise in Sensex sometimes surprises me, sometimes worries me. I don't think fundamentals of economy changes day-to-day. Sensex is driven by corpus inflow of funds," he said while speaking at Hindustan Times Leadership Summit in New Delhi..
Referring to speculators' playing in the market, he said, "To an extent speculators are taking advantage of Sensex... I think things will cool down."
"Sensex is an index of 30 stocks (and) as such it is a number. We don't invest our future in Sensex," said the Finance Minister.
