Expected Move Calculator

What is the Expected Move?

The expected move represents the consensus view of potential stock moves over time. No one knows if the stock will go up or down, but demand and supply for bullish (or bearish) options go through a price discovery process in the market, and the result of that is a consensus of what the crowd (or investors who have placed trades) have priced.

That consensus is derived from cost for at the money options. The bigger the move, the more uncertainty or implied volatility is priced into the options.
