"Options priced" is the implied move going into the report; "close" and "peak" are the earnings-day close-to-close and peak intraday moves. "Faded" = the close gave back more than half of the peak, or reversed sign. Full implied-vs-actual history and the live implied move: MU data page.

Why "good earnings" can still mean a red day
Before the report, options price the size of the expected move — the implied move — and the stock itself is priced for the market's expectations of results and guidance. The reaction is not to the numbers in isolation but to how they compare with what was already priced. That is why MU can beat estimates and fall, or miss and rise; and why the honest question is not "were the numbers good?" but "how far did the stock move against what options priced, and did it hold?" — which is what the season tracker follows for every notable name.
Frequently asked questions
Will MU stock go up after earnings?
Nobody can know in advance. What history says: over 16 tracked reports Micron Technology closed higher on earnings day 7 times and lower 9 times, with an average close move of ±7.6%. The options market prices the expected size of the move, not its direction.
Why does MU stock drop (or jump) after earnings even on good numbers?
Because the stock is priced for expectations, not results. Options price a move of a certain size beforehand; the reaction reflects how results and guidance compare with what was already priced in, plus the unwinding of positioning around the event. A beat can still be a disappointment relative to expectations.
