Wednesday morning. 9:42 AM. A $14M block hits the tape on MU.
Someone sold $14 million in MU $380 puts expiring April 24. 30 DTE. Delta -0.43. Opening position. Grade A.
That's not a hedge. That's someone with real conviction that Micron stays above $380 for the next month. Fourteen million dollars worth of conviction.
What the Tape Looked Like
The block was a single fill — $14M, one shot. Not a sweep broken across exchanges. One clean block trade. That usually means it was negotiated, which means institutional. Retail doesn't place $14M blocks.
At the time, MU was trading around $395. So the $380 strike was about 4% below spot. The put seller is saying: "I'm comfortable owning MU at $380, and I'll collect premium while I wait for it to not happen."
IV on the trade was sitting at 43%. MU has been volatile — earnings reactions, AI narrative, memory pricing cycles. High IV means the premium collected on that put sale was fat. Good setup for a seller.
What Happened
+73.6%. MU held above $380. The puts decayed.
The chart didn't show anything special at 9:42 AM. No breakout, no pattern completion, no technical signal. Just a stock trading sideways. But the tape showed a $14M directional bet that most people would never see.
By the time the chart "confirmed" the move, the block trader was already sitting on premium decay.
Was This the Only MU Flow That Day?
No. There was also an $8.4M MU put sell at the same session — $468 strike, 2 DTE, closing position. Different trade, different thesis. The closing position was someone taking profit on a previous put sale. The $14M block was new money coming in.
That's the kind of context that matters. Two big MU put trades in the same session, but one is new conviction and the other is someone cashing out. Without position classification, they look the same. With it, they tell completely different stories.
The Point
Nobody on Twitter was talking about MU at 9:42 AM Wednesday. No headlines. No chart breakout. Just a $14M block on the options tape that said someone with serious capital was bullish.
You can wait for the chart to confirm. Or you can see the flow when it happens and decide for yourself.
