If there is a pause, the market will go up slightly (since the pause is mostly expected). If there is a hike, there will be a big sell off. Therefore, the odds favor a short position with a tight stop. With that position, I figure, I risk 3 S&P points (the size of my stop) for a potential move down of 25 ES points. The probability of hitting the stop is about 70%. So, the expected value of this position is:
-3 * 0.7 + 25 * 0.3 = 5.5 (points of profit)
