That "expected move" isn't a forecast
Your broker just confessed it doesn't know where the stock is going.
Hey,
Quick one this week, because it saves people real money every earnings season.
Your broker shows an expected move before earnings. Plus or minus 8%. Almost everyone reads that as a prediction of where the stock is going. It isn't. It's the options market admitting it doesn't know, and putting a price on its own uncertainty.
Here's the whole thing in one example. Stock at $100. The nearest straddle - buying the $100 call and the $100 put - costs $8. That $8 is the expected move. Plus or minus 8%. It's not an analyst survey. It's just a price.
And that price is roughly one standard deviation. So the market is saying: about a 68% chance the stock finishes between $92 and $108 by expiration. Which means a full one-in-three chance it finishes outside that band. When a stock gaps 12% and everyone acts shocked, the options market wasn't wrong. It told you that happens a third of the time.
The handle I want you to keep: the expected move is a band of ignorance, not a bullseye.
One more thing that traps people - implied volatility is inflated before earnings, then collapses the moment the news drops. The IV crush. You can be right on direction and still lose on a long call because the volatility you overpaid for evaporated.
What a disciplined trader does: before any earnings trade, find the expected move and ask one question - do I think the stock moves more or less than this band? Then compare it to how the stock has actually moved on past earnings. If it usually moves 5% and the market prices 10%, options are rich. That single question kills most bad trades, because usually you have no edge on it.
This is educational commentary, not personalized financial advice - just the mental model I use.
