周三隐含波动率较高的个股为$维视图像(MVIS.US)$、$FibroGen(FGEN.US)$、$PacWest Bancorp(PACW.US)$等。
近期，伊坎企业成为做空机构兴登堡的目标，市值已蒸发约60亿美元。对冲基金大鳄阿克曼发了一条长推文，称伊坎企业的情况让他想起了2021年Archegos爆仓事件。
他指出，伊坎企业的溢价一直是由高股息收益率维持的，收益是通过向外部股东返还资本产生的，而这些资金反过来又来自公司向投资者出售股票。并表示：IEP的业绩历史和治理结构不足以证明溢价是合理的；相反，它们暗示对其资产净值进行大幅折让是合适的。

三、风险提示
期权是一种合约，赋予持有人在某一特定日期或该日之前的任何时间以固定价格购进或售出一种资产的权利，但不承担义务。期权的价格受多种因素影响，包括标的资产的当前价格、行使价、到期时间和隐含波动率。
隐含波动率反映了市场对期权未来一段时间内的波动预期，它是由期权BS定价模型反推出来的数据，一般将它视为市场情绪的指标。当投资者预期更大的波动性时，他们可能更愿意为期权支付更高的价格以帮助对冲风险，从而导致更高的隐含波动率。
交易员和投资者使用隐含波动率来评估期权价格的吸引力，识别潜在的错误定价，并管理风险敞口。

Implied volatility (IV) is an estimate of a stock's price change during the year. It reflects investors' expectations about the extent of future price fluctuations, and is a key factor in option pricing. The implied volatility of stocks is high, which indicates that market sentiment is extreme. Higher price fluctuations mean greater uncertainty; conversely, low volatility indicates that the market expects less price fluctuations and less uncertainty.

A sharp drop of nearly 50% during the month!$Icahn Enterprises(IEP.US)$Overnight, implied volatility rose more than 35%, close to its highest level in a year.
Recently, Icahn Enterprise became the target of the shorting agency Hindenburg, and its market capitalization has evaporated to about 6 billion US dollars. Hedge fund mogul Ackman posted a long tweet saying that Icahn's situation reminded him of the 2021 Archegos hold-up incident.
He pointed out that Icahn's premium has always been maintained by a high dividend yield. The income is generated by returning capital to external shareholders, and this capital in turn comes from the company's stock sales to investors. It also stated that the IEP's performance history and governance structure are insufficient to justify the premium; on the contrary, they suggest that it is appropriate to make a substantial discount on its net asset value.

III. Risk Reminder
An option is a contract that gives a holder the right, but no obligation, to buy or sell an asset at a fixed price on or at any time prior to that date. The price of an option is affected by a number of factors, including the underlying asset's current price, exercise price, expiration time, and implied volatility.
The implied volatility reflects the market's expectations for options to fluctuate over a period of time to come. It is data inverted by the options BS pricing model, and is generally viewed as an indicator of market sentiment. When investors anticipate greater volatility, they may be more willing to pay higher options to help hedge risks, leading to higher implied volatility.
Traders and investors use implied volatility to assess the appeal of option prices, identify potential mispricing, and manage risk exposure.
