分析$EWY隐含波动率低估，建议做多2028年虚值看涨期权以捕捉波动率扩张及三星/SK海力士上涨红利。

涉及标的： $EWY

中文翻译

2028年$EWY的隐含波动率(IV)可能会大幅上升（目前约44%）。实际波动率(Realized Volatility)的定价应在~65-68%+。因此，仅凭波动率 Vega 扩张，2028年虚值(OTM)长期看涨期权(LEAP Call)的价值可能会再次翻倍。大多数人没有意识到这一点，但其前十大持仓包括： 1. SK Square（集中度排名第5）。其净资产(NAV)的90%是SK海力士(SK Hynix)。 2. 三星生命保险，作为三星电子最大股东之一，其净资产与之挂钩。 3. 三星C&T（$EWY的重要组成部分）持有三星约5%的股份作为其净资产。 4. 三星火灾海上保险：持有三星电子1.49%的股份（鉴于三星电子体量巨大，这构成了其净资产的很大一部分）。 5. 三星C&T -> 拥有三星生命（间接持有三星电子）。 6. 三星电机 / 三星SDS -> 很大程度上与三星电子的资本支出(Capex)周期绑定。 7. 三星电子优先股 - 无投票权优先股被视为独立实体，但权重增加。 SK海力士和三星权重的穿透集中度显著高于算法和市场的认知。你会看到，实际波动率并非如此，因为具有广泛分散性的指数不会随着三星/SK海力士的表现而每天上下波动6%。或者2个月内波动42%... 或者12个月内波动145%... 如果ETF按季度再平衡，你会看到更多权重流入像SK海力士这样波动性更大的名称，以及那些将三星和SK海力士作为净资产的小型所有者的权重上升幅度更大。这又因做市商(MMs)尚未定价的未实现波动率而加剧，来源包括： - 10倍杠杆的三星/SK海力士永续合约。 - 2倍杠杆的三星/SK海力士ETF即将获批和发行。动态对冲这两者将增加三星+SK海力士的波动率，并通过二阶效应 -> $EWY。所以说它是“SK指数”基本上就是三星和SK海力士，并非玩笑。而44%的IV定价来自平坦的韩国10年期指数。当来自存储超级周期的新波动率成为结构性时。 TLDR： - 做多虚值看涨期权实际上是以44% IV买入SK海力士/三星的看涨期权。 - 单独来看，它们的IV可能在73-88%左右。 - 考虑到其他成分股，实际IV可能处于60%中段。 - 如果2028年虚值看涨期权的IV从44%上升到65%+，仅波动率扩张就会增加期权价值。 - 市场有时存在真正的低效，这看起来就是其中之一。这是一笔波动率扩张交易，加上在未来两年的存储、机器人、晶圆代工超级周期中做多SK海力士/三星的额外好处。

英文原文

2028 IV for $EWY will likely go much higher (~44% right now). Realized should be priced around ~65-68%+. So, 2028 OTM leap call value may double again from volatility Vega Expansion alone. Most people don’t this but top holdings include: 1. SK Square (#5 concentration). 90% of their NAV is SK Hynix. 2. Samsung Life Insurance, NAV as one of the largest shareholders of Samsung Electronics. 3. Samsung C&T (large part of $EWY) owns ~5% of Samsung as its NAV. 4. Samsung Fire & Marine Insurance: 1.49% stake in Samsung Electronics (given how big Samsung Electronics is, it makes up a large part of NAV) 5. Samsung C&T -> owns Samsung Life (which indirectly owns Samsung Electronics) 6. Samsung Electro-Mechanics / Samsung SDS -> Largely tethered to Samsung Electronics Capex cycles. 7. Samsung Electronics Preferred Shares - Non-voting preferred shares are treated as separate entities, but increases in weighting. Pass through concentration of SK Hynix and Samsung weightings is significantly higher than algorithms and markets think. And you see that realized, as Indexes with broad diversification don’t go up and down 6% a day depending on Samsung/Sk Hynix performance. Or 42% in 2 months... or 145% in 12 months... If the ETF rebalances quarterly, you get more weighting into more volatile names like SK Hynix and the weighting of smaller owners that own Samsung and SK Hynix as NAV go up more than others. This is compounded with unrealized volatility that MMs have not priced in yet from: - 10x Leverage Samsung / Sk Hynix perps now. - 2x leveraged Samsung / Sk Hynix ETFs approvals and release soon. Dynamically hedging both of these will increase volatility on Samsung + SK Hynix and by second order effect -> $EWY. So, it's not a joke when you say its SK Index is basically Samsung and Sk Hynix. And that 44% IV pricing comes from the flat 10 year Korean index. When the new volatility from the memory supercycle is structural. TLDR: - Long OTM calls is effectively calls on Sk Hynix/Samsung at 44% IV. - Individually they likely sit around 73-88%. - When you account for other names, realized IV may sit in the mid 60's. - Vega expansion on 2028 OTM calls if they go from 44% to 65%+ would increase option values from volatility expansion alone. - There are genuine inefficiencies with the markets sometimes and this looks like one of them. This is a volatility expansion trade coupled with the added benefit of long SK Hynix/Samsung during the memory, robotics, foundry supercycles for the next two years.
