What the IV rush is
IV rush is the build-up of implied volatility in a stock's nearest options as its earnings date approaches. Options price the coming move; the closer the report, the more of that expected move sits in the front expiration, so at-the-money IV climbs — often gently for days, then sharply on the last session. The instant the numbers are public the uncertainty is resolved and IV collapses: the IV crush. Two consequences: (1) holding calls or puts through the report means paying the crush, and (2) the ramp itself can be traded — enter a few days out, exit before the last close, never cross the print. That second idea is what EarningsWatcher's IV Rush strategy and the IV Rush Radar are built around.
How MRVL's implied volatility ramps into the print
Now the real thing. The IV Rush Radar records at-the-money IV twice a day for the last five sessions before every Marvell Technology Group Ltd report. Its most recent release (May 27, 2026) looked like this:
The same path as numbers — IV at each 4pm close, versus the -5d morning reading of 130%:
| Session | ATM IV | vs -5d open |
|---|---|---|
| -5d 4pm | 126% | -3% |
| -4d 4pm | 120% | -8% |
| -3d 4pm | 121% | -7% |
| -2d 4pm | 188% | +44% |
| -1d 4pm | 208% | +60% |
Across all 7 tracked reports the five-session ramp averaged +113% and the last day alone +21%.

What holding MRVL options through the print actually cost
The clearest way to see IV crush: an at-the-money straddle bought one minute before the last close before Marvell Technology Group Ltd's report, marked at 10:00 the next morning. Both legs together — so this is the premium lost even after the stock moved:
| Report | ATM straddle, last close → 10am next day |
|---|---|
| Mar 5, 2025 | +45% |
| Dec 3, 2024 | +119% |

Frequently asked questions
Should I buy MRVL before earnings?
That is a decision only you can make, and this page does not give advice. What the data says: options price a move of ±12.7% for the Aug 27, 2026 report, so a long call or put needs Marvell Technology Group Ltd to move more than that in the right direction to profit after IV crush. Implied volatility has climbed +113% on average over the final five sessions, which is why some traders trade the ramp itself and exit before the print.
Does MRVL implied volatility go up before earnings?
Usually. Across Marvell Technology Group Ltd's last 7 reports at-the-money IV rose into the print 7 times, averaging +113% from five sessions out to the last close, with the last day alone averaging +21%. Into its May 27, 2026 report IV went from 130% to 208%.
When does MRVL IV peak before earnings?
At the last close before the report — the final session before the print carries the biggest step for most names, which is why an IV-rush trade is exited before that close and never held through the announcement.
What is MRVL's implied move for the next earnings?
Options currently price about ±12.7% for Aug 27, 2026 (after market close); the 10-year average move is about ±10.2%.
