$MU just ran a full roundtrip — 890 to 990 back to 890 in four days. That's a 100-point whipsaw on zero follow-through. Rip higher got sold into, support gave out fast. If you're working short-dated calls or puts here, that kind of chop kills premium. Better to wait for a clean break above 1000 or a retest of 870 with some actual structure. Right now it's just noise.
