How can people even be treating oil falling as a bearish signal? Typical, really. They were ignoring it as a bearish signal when it was going up and now the economic data have all been messed up, most likely at least 50% if not 90% due to the rise in oil, and now it's going back down and it's bearish? Also like with most things, it's not the level which matters most (as oil had been slowly and gradually trending up without causing any problems earlier) but the rate of change. I'd be more worried if oil was gradually and steadily coming off if I was looking for deflation fears. Right now it's just the Middle East supply speculation trade unwinding.
Anyone could've seen the soft economic data coming from 10 miles away and the improving data is also foreseeable from an equal distance as long as oil doesn't rebound.
So imo treating falling oil as a bearish signal (which is what a lot of the media is doing) = oversoldness and treating rising oil as a non-signal or even bullish (inflation trade here we come!) = overbougtness.
