prices drop. Crude oil prices are down nearly 35% from 2014 and 145% from 2013
till Dec 2015. Crude oil prices starts dropping in July 2014 and found bottom

0.11 on monthly closing that reflects slightly positive correlation. In

Oil stocks and oil prices are positively
correlated most of the time and also negatively to some stocks. The degree of
correlation is likely to vary over time. Market technicians know that equities
lead the underlying commodity. This is partly because equities (or stocks) are
widely held whereas commodities tend to be tightly traded. Just as falling gold
stocks foreshadowed falling gold prices, high energy stock prices might be signaling
a breakout in the price of crude. Here we tried to find some correlation
between Crude Oil and Indian Energy Stocks.
