Both bottomed on December 24th.  Both have rallied since then with stocks approaching their all time highs but crude far from that.

Of late, I've noticed that the intraday charts are also correlating.  That's a little annoying to me because I don't usually take an interest in trading crude.  

I'm speculating here on the nature of the correlation.  Is it a reflection of the world economic slow down narrative?  As the economy picks up, demand for energy picks up.  (and visa versa)   

Or is it a simple matter of energy stocks being a large component of the S&P500?

I know next to nothing about crude oil fundamentals.

I'm going to start following the oil threads on MF.
