In fact,<b>the percentage of SPX option volume happening in 3rd Friday expirations is at an all-time low,</b>and is now smaller than the percentage happening in Monday and Wednesday expirations. One explanation for heightened ultra-short-dated volumes is the strong single stock volumes: and here an interest suggesting from Goldman - \"to the extent market makers are unable to cover the short single stock gamma generated by retail investors’ call buying, they may be actively trading long positions in strips of ultra-short-dated SPX index options to offset this gamma.\"</p><p><blockquote>正如高盛所解释的那样，投资者越来越多地采用SPX到期的完整日历，包括每周一和周三的到期，因为他们围绕事件调整了自己的观点。事实上，<b>第三个周五到期的SPX期权交易量百分比处于历史最低点，</b>现在低于周一和周三到期的百分比。超短期交易量增加的一个解释是强劲的单一股票交易量：高盛提出了一个兴趣——“在某种程度上，做市商无法弥补散户投资者看涨期权买入产生的单一股票空头伽马，他们可能会积极交易超短期SPX指数期权的多头头寸，以抵消这种伽马。”</blockquote></p><p> <img src=\"https://static.tigerbbs.com/bd0e886a62a61c70b0f299bd6c032a24\" tg-width=\"954\" tg-height=\"1128\" referrerpolicy=\"no-referrer\"></p><p><blockquote></blockquote></p><p> Why is this important? because if this trend is large enough, it directly contributes to low implied and realized correlation.<b>Ironically, by ramping single name, \"most-shorted names\", retail investors are ushering a period of unorthodox calm across the rest of the market!</b></p><p><blockquote>为什么这很重要？因为如果这种趋势足够大，它会直接导致低隐含和实现的相关性。<b>具有讽刺意味的是，通过增加单一名称“最受做空的名称”，散户投资者正在市场的其他部分迎来一段非正统的平静时期！</b></blockquote></p><p></p>","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html;

Furthermore, with stocks at all time highs, it is to be expected that most of the June open interest is below the current SPX spot price. As shown in the chart below, the dual peaks are at 3,900 and 4,150. This means that after Friday, there may be a certain \"anti\"-gravity around those spots until gamma is refilled.\n\nThe Goldman strategist then explains what he believes is below the abnormally low level of realized market vol, noting that - as we discussed last week - it is consistent with long gamma positioning. Consider that SPXrealized volatility over the past 13 trading days has been just 5.1% - the lowest 13-day realized vol since 2019.\n\nThis contrasts with extreme volatility in pockets of the single stock market; AMC, which had the highest contract volume among single stocks last week (but far less notional volume at$7bln/day than AMZN’s leading $120bln/day), has had close to 400% realized vol over the same period.\n\nThen, as Nomura's Charlie McElligott first noted last week, Goldman's derivatives team agrees thatthe extremely low SPX realized volatility is consistent with the possibility that 18-Jun has left “the street” long index gamma, in which case Fishman echoeswhat we said last week, namely that \"realized volatility could pick up once positions are cleaner. \"Meanwhile, the rising beta of VIX futures to the SPX indicates that investors expect short gamma dynamics to pick up should markets sell off. Translation:the market will become much more volatile in a selloff.\n\nMeanwhile, and in keeping with the latest memo stock squeeze, Goldman also notes that while single stock option volumes continue to be high, it is well short of Q1 peaks. The large percentage of all single stock option activity driven by retail, and the predictive value of retail activity, have both heightened the attention on the single stock option market in recent weeks. Recent growth in single stock option activity has been concentrated in low-share-price stocks, leaving a shar prise in contract-volume over the past two weeks that has not been matched by notional volume. When adjusting notional volume for the size of the equity market, Goldman finds that single stock volume has actually been on the low of its 2021 range over the past two weeks which means that the latest ramps had little to no gamma squeeze components to them.\n\nOne final point which we discussed recently and which is in keeping with the growing retail participation in trading, is Goldman's observation that the trend toward shorter-dated SPX options (weeklies) and away from quarterlies, continues. That also is one of the reasons why Friday’s SPX expiration is smaller than many recent quarterlies, and why as it as approached expiration, its trading volume has been falling.\nAs Goldman explains, investors have been increasingly adopting the full calendar of SPX expirations, including expirations every Monday and Wednesday, as they tailor their views around events. In fact,the percentage of SPX option volume happening in 3rd Friday expirations is at an all-time low,and is now smaller than the percentage happening in Monday and Wednesday expirations.
