On August 18, Micron Technology fell 4.63% in regular trading, trading at $964.55/share, with turnover of $5.648 billion. The decline followed a cumulative 17.5% surge over the prior five trading sessions, triggering concentrated profit-taking pressure.

On the news front, legendary investor Druckenmiller's latest 13F filing revealed a complete liquidation of his Micron position. Bridgewater Associates previously disclosed reducing its Micron stake by approximately 92%, while Appaloosa Fund trimmed its holding by 41%. In the options market, a notable $624,000 sell order targeting far-dated $1,200 strike calls emerged, combined with put buying activity, signaling institutional bets that near-term upside remains capped.

The broader storage sector declined in tandem, with Western Digital falling over 7%, Sandisk and Seagate dropping over 6%, and SK Hynix losing over 5%. The semiconductor sector saw broad weakness, with Marvell Technology down 6.26%, Intel down 5.19%, and AMD down 4.09%.
