I bought some QQQ Dec 18th $275 puts just now. My stop is the high of the day, $299.14. With QQQ trading at $295, that's only 4 points of risk for what could be 20 points of gain, based upon the last time the hourly stochastic dropped below its overbought level (75) on Oct 14th (see chart). The put cost me $4.00 and at today's high in the QQQ that put was trading at $3.00. Doing the math, risk $1.00 to make at least $10. For the insane only.
