I've been noticing a lot of spikes across assets lately. Always timed a minute or two before the official release print. That used to constitute a somewhat unusual occurrence. One expects relative calm before the storm. Now it seems to happen with every bit of data. It could be chalked up to algos pre-positioning in anticipation. But many times if you are tracking fellow traders on your twitter feed as well as the price action, you'll notice a cry of "Leaked!" coupled with the price swings. I always assumed something far more nefarious and insidery was taking place. Powerful forces manipulating markets for various geo-political ends and so forth. So am somewhat relieved to see ordinary everyday greed to be the culprit. Am waiting for a Nanex style expose on this phenomenon.
