Micron closed at USD 1,074.89, down 2.05%.

Large options flow in Micron showed a clear bullish tilt, led by a $3.83 million bull call spread targeting $1,200–$1,350 by late 2026. A separate $2.31 million out-of-the-money call sale at $1,300 capped upside, but the dominant institutional activity leaned toward further appreciation rather than a top-calling stance.

Options Indicators

Micron’s implied volatility is 51.88%, and with an IV percentile of just 0.40%, current volatility sits at the very low end of its historical range, indicating that options are cheaply priced rather than expensive. The IV/HV ratio of 1.04 suggests implied volatility is only slightly above realized volatility, reinforcing the view that current option premiums are fairly restrained and that the market is not demanding a significant volatility premium at the moment.

The Call/Put volume ratio is 1.60.

Large Trades

A bullish call spread with a net debit of $3.83 million was the largest featured trade, built by buying 1,100 December 18, 2026 $1,200.00 calls and selling 1,100 December 18, 2026 $1,350.00 calls. Both strikes sit out of the money versus the $1,074.89 reference stock price, making this a defined-risk upside structure rather than an immediate intrinsic-value play. As a bull call spread, it reflects a directional bet on further gains in Micron while capping upside above $1,350.00 in exchange for reducing upfront premium outlay; the net debit points to a premium-paid bullish stance with disciplined risk control.

An out-of-the-money call sale worth $2.31 million was the other displayed large trade, consisting of selling 2,236 October 30, 2026 $1,300.00 calls. With the strike above the current stock reference, the position expresses a bearish-to-neutral view on near-term upside, suggesting the seller sees limited probability of Micron rallying through $1,300.00 by expiration and is likely aiming to collect premium or fade an overly aggressive upside scenario. Overall, the large-trade flow leans clearly bullish: the dominant trade was a sizable upside call spread financed as a net debit, and the broader block activity shows bullish positioning outweighing bearish flow, indicating institutional interest remains skewed toward further appreciation in Micron even as some traders monetize or cap upside through call selling.

Strategy Reference

For a low assignment probability with a short call, a seller could favor the December 2026 $1,350.00 strike above the $1,300.00 sold line; alternatively, a bull put spread near $1,000.00–$1,050.00 may express bullish direction with lower margin than a naked short put.
