exactly............. Options expiration week is the week in which Wall Street tends to gun the market higher in an effort to insure the most puts ( and sellers of calls) have their contracts expire worthless. This clear manipulation is funded by the Federal Reserve, which juices the market almost without exception during these weeks. This practice occurs even when the FED is not actively engaged in Quantitative Easing or QE. and thats how you have a free market system. I wonder what the FED balance sheet looks like currently? I wonder. http://stockcharts.com/c-sc/sc?s=SPY&p=1&yr=0&mn=0&dy=20&i=p94618819863&a=257672095&r=1418850273316
