Micron Technology (MU) shares climbed 5.6% to $809.50 by 10:59 AM, but it was the options market that really stole the show. The spotlight was on the May-15-26 $900 call contract, which rocketed to a volume of 13,849 contracts—about 6.1% of all MU options traded this morning, and a clear outlier compared to typical single-strike volumes.
Big Numbers: Single Contract Activity Highlights Fresh Bullish Energy
Why does this strike matter? The $900 call is out-of-the-money, yet it's attracting serious attention as Micron surges. The contract launched with an opening trade of $10.30 and a high of $12.00, before pulling back to last trade at $7.40 (VWAP: $6.85). For context, yesterday's closing price was $4.93—meaning intraday momentum has added significant mark-to-market gains for early buyers.

Volatility Falls Despite Heavy Trading—What Does the Data Say?
Here’s where today’s action gets even more interesting: Implied volatility (IV) for the $900 call actually dropped as trading activity picked up. The average IV for these contracts was 103.0 this morning—down 10.9% from the previous day’s close of 115.7. Even with trading reaching for the sky, IV moved from an early high of 110.6 to a session low of 97.3, with the last observed IV at 100.9. Normally, huge call volume would push IV higher, so this drop hints at sellers (possibly institutions) providing liquidity into heightened demand.
| IV Stats | Value (%) |
|---|---|
| VWIV | 103.0 |
| Previous Day Close IV | 115.7 |
| Change from Previous IV | -10.9 |
| Open IV | 108.9 |
| Session Low IV | 97.3 |
| Session High IV | 110.6 |
| Last IV | 100.9 |
Order Flow Tilts Bullish, Led by Retail—But Not All Bets Are Equal
Order flow in this contract is decisively bullish: 59.6% of all trades were on the buy side, compared to 40.4% on the sell. Small traders (whom many would call retail investors) made up a whopping 73% of the flow, while large/professional trades accounted for just 27%. This is an unusually high level of retail conviction for an out-of-the-money call, especially on such a volatile day. The real question: are they buying with eyes on a further rally, or just chasing today’s momentum?
| Order Flow | Value (%) |
|---|---|
| Buy Side | 59.6 |
| Sell Side | 40.4 |
| Large/Pro Traders | 27 |
| Small/Retail Traders | 73 |
How Does This Fit the Broader Picture?—IV Decrease, Retail Buying, and a Possible Momentum Surge
Despite the huge uptick in call buying, the falling implied volatility tells us that sellers (likely market makers or institutional traders) are willing to provide supply and don’t see explosive risk ahead—at least in the short term. The day-over-day increase in open interest (+752 contracts as of the last update) signals bullish positioning over the prior day, but keep in mind today’s flurry won’t show up until tomorrow’s open interest reports.
For readers: Today’s surge in the $900 call is a rare example of retail momentum making a splash in deep out-of-the-money calls. The lower IV might mean options are relatively ‘cheap’ compared to just 24 hours ago, or it could mean the smart money is betting the rally won’t last. If you’re watching MU, keep a close eye on how open interest updates in the next session, and whether buyers keep the pressure on as expiry comes closer.
