Options Flow Snapshot
On August 13, 2026, Micron Technology (MU) near-term options (expiring August 14, 2026) showed elevated activity: total volume of 376,719 contracts, total premium turnover of ~$1.016 billion, with 250,704 call contracts and 126,015 put contracts, for a call/put volume ratio of ~1.99. The largest active contract was MU260814C00950000, a $950 strike call option expiring August 14, with 23,312 contracts traded and $72.15 million in premium turnover. The ATM straddle implied a 6.94% near-term price move, with average near-the-money call IV at 125.0% and put IV at 99.4%, a 25.7 percentage point call-over-put skew.
Signal Read-Through
This is a near-dated upside skew and volume concentration signal. Key traits include outsized call volume relative to puts, higher call implied volatility than puts, and concentrated large-size call trades, indicating the market is pricing in strong near-term upside volatility for MU over the single trading day until expiration. Total premium turnover equals ~3.2% of the underlying stock’s daily dollar volume, marking a significant trading event.
Fundamental and Event Cross-Check
Two concrete independent signals align with this options activity: 1) On July 28, 2026, CEO Sanjay Mehrotra filed Form 4 disclosures totaling ~$7.9 million in company stock sales; 2) As of December 31, 2025, institutional holdings accounted for 78.4% of MU’s float, with 2,805 institutional holders, an increase of 563 from prior periods. Contemporaneous August 13, 2026 media coverage focused on Micron’s AI memory business positioning, with no direct link to the options flow.
Follow-Up Markers
This signal does not confirm the source of the options flow (retail vs institutional, hedging vs directional positioning) or predict the actual August 14, 2026 stock price movement. It only reflects current market pricing of short-term volatility. Key items to watch include August 14’s actual price action, open interest changes ahead of expiration, and whether the upside skew persists in subsequent trading sessions.
期权成交结构
2026年8月13日，美光科技（MU）的近月期权合约（到期日2026年8月14日）出现显著成交活动：总成交量376,719张，总权利金成交额约10.16亿美元，其中认购期权成交量250,704张、认沽期权126,015张，认购/认沽成交量比约1.99。最大单笔活跃合约为MU260814C00950000（8月14日到期、行权价950美元的认购期权），成交量23,312张，权利金成交额7215万美元。当日平价期权（ATM）跨式组合隐含涨幅约6.94%，平价附近认购期权隐含波动率（IV）较认沽期权高25.7个百分点，平均认购IV达125.0%，认沽IV为99.4%。
信号含义
该信号属于近到期日上行偏度与成交集中信号，核心特征为认购期权成交量显著高于认沽期权，且认购隐含波动率高于认沽期权，显示市场对美光科技未来1个交易日的上行波动预期较强，大额认购合约的集中成交也表明存在明确的方向性头寸布局。本次权利金成交额约占当日股票成交额的3.2%，成交规模显著。
基本面与事件交叉验证
可交叉验证的独立信号包括：1）2026年7月28日，美光CEO Sanjay Mehrotra通过Form 4文件披露累计减持约790万美元公司股票；2）截至2025年12月31日，美光机构持仓占浮筹78.4%，共有2805家机构持有者，较此前增加563家。2026年8月13日同步有多家媒体发布关于美光AI内存业务布局的相关报道，但未对本次期权成交做出直接解释。
后续关注
该信号无法证明期权成交的资金来源（零售/机构、套保/方向性持仓），也无法直接预测8月14日的实际股价走势，仅反映当前市场对美光短期波动的定价预期。后续需关注8月14日的实际股价表现、期权到期前的持仓变化，以及是否有进一步的大额期权成交延续该上行偏度。
