Following yesterday's S&P surge on the worst hard economic data (not some fluffy survey conducted by a conflicted firm whose parent just IPOed and is thus in desperate need to perpetuate the market euphoria) in five years, there is little one can comment on how "markets" react to news. Good news, bad news... whatever - as long as it is flashing red, the HFT algos will send momentum higher. The only hope of some normalization is that following the latest revelation of just how rigged the market is due to various HFT firms, something will finally change. Alas, as we have said since the flash crash, there won't be any real attempts at fixing the broken market structure until the next, and far more vicious flash crash - one from which not even the NY Fed-Citadel PPT JV will be able to recover. For now, keep an eye on the USDJPY - as has been the case lately, the overnight USDJPY trading team has taken it lower ahead of the traditional US day session rebound which also pushes the S&P higher with it. For now the surge is missing but it won't be for longer - expect the traditional USDJPY ramp just before or as US stocks open for trading.
