The spike in crude oil prices has again created trouble for the Nifty and Sensex, as it has done a number of times in the past two months. Not surprising, though.

So, till clarity emerges on the possible trajectory of oil prices, the volatility quotient will remain high. That said, this is not the first time oil prices are spiking. They have done so in the past. The difference this time is that it is perhaps not only about the prices, but something more.
