first part - under this scenario, is there opportunity for someone? what would they do? what would the result be on the respective prices of cash and futures? would they now be moving back in line?
second part - bonds one quarter, oil the last quarter, spoo the next month, dow the previous week, etc etc. soon we will be back to the price of gold leading the stock market. read up on sector rotation could be of some help and then considering the same principals on the wider commodity markets.
the bottom line is: does it matter? trying to overcomplicate everything with meanings, theory and analysis is imo just a crutch used by many to give them themselves the illusion they are being clever and working hard. just like our society demands. unfortunately the market or your account cares very little for this. what is more important is learning the mental skills to pull the trigger correctly, and at the right time. if you cant do that, no amount of knowledge is going to help you.
