Who moves this market, Micron or Tesla?
The biggest stock on your screen is not moving this market. Everybody watches the giants. Apple, Tesla, the four-trillion-dollar names, and you assume the biggest company is the one that pushes the tape around. Today I want to show you why that is wrong, and why the number you are watching is the wrong number. Let me put two stocks next to each other. Tesla is a $1.5 trillion company with 50% implied volatility. Micron is a $1.1 trillion company with 100% implied volatility. Quick definition before we go on. Implied volatility is the market’s estimate of how much a stock is about to move. A 100% reading means the market expects roughly double the swing of a stock sitting at 50%. So here is the question.
