《Why Your Options Lose Value After Earnings》
AI 摘要 · LMT 在财报后垂直拉升，走势显得过度拉伸，预计将大幅回落至关键支撑位；该股在 645 和 650 附近的趋势线处受阻，RSI 高于 70 处于超买，成交量正在萎缩，今日看跌期权成交量超过看涨期权。说话者看空并买入看跌期权。
在我们进一步深入之前，我先来看几周前的一个交易机会。国防板块的巨头之一，Lockheed Martin。最初我们放弃了它，因为我们买入和卖出之间的价差，或者说买价和卖价之间的价差太宽了。
大约有20%，对于滑点来说这算宽的。这些行权价的流动性不好，而且作为买方，权利金太贵了。
Before we get a little further into that, I'm looking at a setup from a couple weeks ago. One of the defense beasts, Lockheed Martin. Originally, we passed on it because the spread between us buying and us selling or excuse me, between the bid and the ask, it was too wide.
It was about 20% and that's wide for slippage. The strikes weren't liquid and the premiums were too expensive as a buyer.
