$EWY 看起来即将变得更加波动。 做市商可能没有正确地将跳跃期权隐含波动率(IV)定价,因为 IV 可能会扩张至 55% 以上。 有两个原因源于未实现(但即将到来)的波动性。 - 10 倍杠杆的三星/SK 海力士通过去中心化金融(DeFi) 已经出现,因为它们开始产能爬坡。 如果规模变得很大,这会在期货(如 $EWY)的清算和对冲上产生大量的未实现波动性。 $EWY 由一半的 SK 海力士/三星组成,而韩国指数本身已经非常波动。 - 三星和 SK 海力士的 2 倍杠杆单只股票 ETF 即将到来 2026 年 1 月,韩国监管机构正式宣布允许国内 2 倍杠杆单只股票 ETF。 同样,这增加了未实现的波动性。 但就目前的期权 IV 定价而言,$EWY 的波动幅度相当极端。 如果非要打个比方,它的百分比波动范围肯定大于 $MRVL(IV 为 55-56%,而 $EWY 仍为 41%)。 三星的对应物可能是 $MU(约 70%),SK 海力士更接近 $SNDK(91%),但可能在 70-80% 范围内。 而且……韩国指数基本上就是 SK 海力士和三星。 随着三星/SK 海力士开始从存储超级周期中重新评级,这种波动性可能会成为新常态。但做市商可能仍然在使用广义自回归条件异方差(GARCH) 模型或基于长期平均值(当时指数完全平坦)的波动率预测投影。 来自 10 倍杠杆衍生品的数量将仅仅为这些个股的对手方和做市商创造更多的对冲/波动性 -> 这会滞后地反映在 $EWY 的定价中。 简而言之:随着做市商未能正确定价 IV 和未实现波动性,$EWY 看涨期权可能会从 Vega 扩张中受益。

英文原文

$EWY looks like it's about to get more volatile. Market makers might not be pricing in leap option IV correctly as IV may expand past 55%. Two reasons due to unrealized (but upcoming) volatility. - 10X leveraged Samsung / Sk Hynix through Defi are here as they begin ramp-up. This creates a great amount of unrealized volatility from liquidations and hedging on futures like $EWY if this ends up becoming large. $EWY is half Sk Hynix / Samsung, and the South Korean index is already really volatile. - 2x leveraged single-stock ETFs for Samsung and SK Hynix are coming In January 2026, South Korean regulators officially announced they will permit domestic 2x leveraged single-stock ETFs. Again, this just adds to unrealized volatility. But as it stands right now regarding option IV pricing. $EWY moves pretty extreme amounts. If I had to give a comparison, it definitely moves in greater % ranges than $MRVL, which sits at 55-56% IV (while $EWY is 41% still). Samsung's equivalent is probably $MU (70%-ish), Sk Hynix is closer to $SNDK (91%) but likely in 70-80% range. And... South Korea's index is basically just Sk Hynix and Samsung. This volatility would likely be the new norm as Samsung/SK Hynix begin their re-rating from the memory supercycle. But MMs are still probably using garchr models or volatility forecasting projections against long-term averages (where index was completely flat) And the amount of leveraged derivatives from 10x will just create more hedging/volatility on these individual stocks from counterparties and market makers -> that gets priced in late to $EWY. TLDR: $EWY calls likely benefit from vega expansion as MMs aren't pricing in IV and unrealized volatility correctly.
