MU is confirming the thesis fundamentally while becoming a completely different trade technically.
At this point I would not be looking to buy it, sell calls against it, or pay inflated put premium. I would be waiting for the parabolic move to show exhaustion.
Our weekly chart is very clear:
Zone Meaning
$875 area 7/8 weak stop-and-reverse; level it has effectively hit today
$890–$894 Today’s high / 2.618 extension confluence; first serious rejection watch
$1,000 8/8 ultimate resistance if momentum simply refuses to die
$1,055–$1,156 3.618 to 4.236 blow-off territory; the kind of second-extension insanity you saw in gold
MU traded as high as about $890.47 today, almost exactly into your $893.89 2.618 extension, after being up more than 16% intraday.
