AI\u002F存储板块反弹”三股力量叠加。\u003C\u002Fp>\u003Cfigure class=\"image\">\u003Cimg src=\"\u002Fimg\u002Fstockwebsiteblob\u002Fweb-202609-stk\u002FUploader5d3498552476457fb0ed574621800582.png\" width=\"598\" height=\"154\">\u003C\u002Ffigure>\u003Cp>\u003Cstrong>申明：因我们是 SNDK内部人士的原因，我们持有SNDK的原始股，以下分析只代表个人立场\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>\u003Cstrong>我认为今天最值得注意的是下面几个因素：\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>1. 出现了非常夸张的 SNDK 看涨期权买盘。今天市场出现超过9,000万美元的短期期权资金涌入INTC、MRVL、MU 和 SNDK，其中SNDK 一只股票就占了约4,100万美元，资金集中买入10月2日到期、执行价 $1,600 的 Call。\u003C\u002Fp>\u003Cfigure class=\"image\">\u003Cimg src=\"\u002Fimg\u002Fstockwebsiteblob\u002Fweb-202609-stk\u002FUploaderd72d50af487e450dadbf241ee4cb2fb7.png\" width=\"808\" height=\"842\">\u003C\u002Ffigure>\u003Cp>这笔交易非常特殊，因为SNDK 今天本来就已经站在$1,600 上方。如此大规模、短期限的Call 买盘很容易产生 Gamma hedging：如果做市商是Call 的卖方，为了对冲风险，就需要不断买入SNDK 正股，股价越涨，需要买的股票可能越多。\u003Cstrong>根据美股大数据 StockWe.com的量化追踪，机构今天在大单买入56亿美元，暗池买入5亿美元。\u003C\u002Fstrong>\u003C\u002Fp>\u003Cfigure class=\"image\">\u003Cimg src=\"\u002Fimg\u002Fstockwebsiteblob\u002Fweb-202609-stk\u002FUploaderb4ffaaeebb684db4b32a7c522bc254d0.png\" width=\"656\" height=\"584\">\u003C\u002Ffigure>\u003Cp>所以今天后半段从“上涨”演变成接近+11%，期权资金很可能是一个重要的加速器。\u003C\u002Fp>\u003Cp>但需要注意：目前并不知道这个神秘买家是谁，所以不能把这$4,100 万 Call 当成“有人提前知道内幕消息”。它只能说明今天资金的看涨押注明显异常。\u003C\u002Fp>\u003Cp>据Citadel Securities数据，本次到期的期权名义价值约为7万亿美元，规模为史上第二大，其中约60%在开盘时完成结算或展期。 \u003C\u002Fp>\u003Cp>城堡证券由Scott Rubner领衔的市场情报团队提示，此前压低实际波动率的期权头寸退场后，价格会更容易受到资金流影响。嘉信理财交易策略主管Joe Mazzola也提醒，季末调仓可能放大波动。 \u003C\u002Fp>\u003Cp>\u003Cstrong>第二个非常重要的因素，是SNDK 即将在下周一正式进入S&P 100。\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>S&P 已经宣布，SanDisk、Dell、Palo Alto Networks 和 Arista Networks 将于 9月21日正式加入S&P 100。SNDK 的消息并不是今天才公布，因此不能说这是今天突然上涨11%的“新闻催化剂”，但今天是指数调整生效前的最后一个交易日。\u003C\u002Fp>\u003Cp>这点非常关键。\u003C\u002Fp>\u003Cp>\u003Cstrong>追踪 S&P 100 的被动基金需要按照新的指数权重调整仓位，同时还有大量主动基金、量化基金和套利交易者会提前进行index rebalance \u002F index front-running。\u003C\u002Fstrong>这是美股投资网创始人兼CEO，Ken，他在华尔街，纽约证券交易所担任分析师时，职责之一。\u003C\u002Fp>\u003Cp>因此今天会出现一个很典型的情况：\u003C\u002Fp>\u003Cp>\u003Cstrong>被动资金必须买 + 套利资金提前买 + Call 做市商对冲买。\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>三种资金可能同时集中到SNDK 上。\u003C\u002Fp>\u003Cp>所以我认为，今天SNDK 明显跑赢 MU 和 WDC，并不是偶然。\u003C\u002Fp>\u003Cp>其中我尤其关注$4,100万的 10月2日 $1,600 Call。\u003C\u002Fp>\u003Cp>因为这笔交易到期只有两周左右，绝对不是传统长期投资者买LEAPS 的行为。这意味着有人在非常明确地押注未来两周SNDK 继续保持强势和高波动率。\u003C\u002Fp>\u003Cp> \u003C\u002Fp>\u003Cp>美股投资网是一家专门研究美股的金融科技公司，2008年成立于美国硅谷，由前纽约证券交易所分析师Ken创立，联合多位摩根斯坦利分析师，谷歌
