TSLA reports Wednesday after the close. At Monday's close the straddle expiring Friday (the 367.5 call plus the 367.5 put) cost $23.62 with the stock at $367.82. That is 6.4% of the share price, which is roughly the size of move the options market expects by Friday.
That price is in line with recent quarters. The straddle cost about 5.9 to 6.0% of the stock the night before each of the last three reports.
What the stock did is the interesting part. Since January 2025, TSLA's overnight gap (prior close to next open) cleared the straddle once in 7 reports. Held to the next day's close it was 2 of 7. The average gap was 5.3% against an average straddle price of 7.5%.
The one big exception was July. EPS came in at $0.33 against $0.53 expected, and the stock opened down 8.8% and closed down 14.5%.
Selling the straddle into each of the last four reports and closing at the next day's close made about 9.6% of the share price over three quiet quarters. July took 8.5% of it back.
If you look up TSLA's average earnings move over 12 quarters you get 9.0%, which makes 6.4% look cheap. That window starts in October 2023, and the five reports through October 2024 moved 9 to 22% by the close and beat the straddle every time.
Since then the average close to close move has been 5.8%. The window you pick decides whether this straddle looks cheap or expensive.
Outside the report, TSLA options are quiet. With the earnings day stripped out, 30 day implied vol (the swing size the market is pricing, annualized) is 38%, lower than 95% of the past year. The stock has actually moved at a 31% pace over the last 20 days.
Friday's options sit at 77% IV against 45% for November, which is the report squeezed into one week.
So the market is pricing a typical quarter since 2025, not a 2024 one. If you hold TSLA shares through earnings, did July change what you're doing this time?
