RE: MM games...."price is falling before inventory release.........looks like the MMs will spike the price after the inventory regardless of the draw........do the opposite for a change to tick people off......"
This post is about as clueless as one can get. The price of HNU was falling because the price of NG was falling. The MM's who actually work HNU have nothign to do with it. In facr, I would be shocked if HNU used MM's. The main job of an MM is to provide liquidity andmaek a market by posting a bid/ask. With ETF's such as these that derive their value from the price of something else (in this case, NG futures) MM's would be redundant.
In any case, if HNU ever moved (on an intraday basis) in a way that was different then actual NG moved, there are HFT computer programs who would detect that arbitrage oppourtunity and eliminate it in milliseconds. You would never see it.
