全球AI股票遭抛售，SK海力士暴跌12%……是崩盘还是健康回调？
全球AI股因获利了结和杠杆下跌，但强劲的HBM需求和AI资本开支表明这是健康回调而非崩盘。
- AI基本面依然完好，HBM仍是瓶颈，存储周期仍在继续。
- AI资本开支未显著收缩，支撑行业长期需求。
- 当前的抛售是由交易结构和获利了结驱动的，而非基本面崩溃。
- 科技股前期仓位拥挤，容易受到利率预期变化的扰动。
- 市场对不完美信息或谣言极度敏感，容易将其放大为抛售理由。
- 韩国等市场的杠杆和ETF结构会放大波动，并触发强制平仓的连锁反应。
全球AI板块今日的回调，乍看之下确实让不少人感到一丝恐慌，尤其是在韩国，SK海力士一度下跌超过10%，三星电子紧随其后，杠杆型ETF遭遇放大抛售，美国纳斯达克期货也同步走弱。整个AI产业链仿佛突然急踩了刹车。但冷静下来一看，这更像是在高位之后的一次集中降温，而非基本面出现问题。
韩国受到冲击最严重，主要因为它对AI内存芯片的情绪放大作用明显。此前SK海力士涨幅过大，甚至一度超越三星的市值。在如此高位，自然成为最先被获利了结的目标。一旦情绪转弱，前期表现最强的标的往往最先被抛售。
与此同时，市场现在对任何“不完美信息”都极度敏感。例如关于HBM和DRAM的传闻，很容易在高位环境中被放大为卖出理由，因为资金已从追逐收益转向锁定利润。此外，韩国市场的高杠杆和ETF结构意味着一旦价格下跌，便会触发强制平仓，形成指数压力→情绪恶化→进一步止损的连锁反应。因此，尽管跌幅看起来剧烈，但更多是交易结构放大波动的结果，而非行业基本面崩塌。
美国股市的逻辑也类似。科技股此前已过于拥挤，加上利率预期扰动高估值资产，AI相关股票自然被一并拖累。但基本面并未改变：HBM仍是瓶颈，内存周期仍在进行中，AI资本开支也未显著收缩。关键仍在于美光（Micron）的财报能否验证定价与需求情况。
目前的局面更像从“盲目买入AI”转向“需要证明持续超预期”。市场正从讲故事转向业绩验证。未来关注重点将有三点：美国市场稳定性、美光的指引以及利率趋势。若局势趋于稳定，这更可能是一次情绪重置，而非趋势逆转。AI并未结束，只是交易方式变了。

My portfolio has \~25% of investment in SK Hynix and here's my take:
- The 12% drop by all means does not reflect anything negative about SK Hynix's earnings ability and its leadership in the HBM market.
- The 12% drop is mostly triggered by South Korea highest financial regulator's criticism towards leveraged ETFs tracking either SK Hynix, Samsung or both. Retail investors in South Korea are gambling with these ETFs, which to some extent, are incentivised by security providers.
- The second trigger is because Mag 7 are suffering from equity drawdowns (again, not earnings), so as a key supplier, SK would also suffer.
- Obviously you could argue that people think valuations are stretched and hence taking the profits but this is as vague as it could get without data.
Things I'd pay close attention to/be aware:
- Micron's earnings report on Wednesday. An indicator of whether the memory sector deserves it's fast-growing trading multiples. Micron has the most expensive trading multiples, so it's fair that its performance, at the very least, is a starting point to justify the sector's valuation.
- If you look from a trading multiples perspective (e.g. P/S, P/E, P/B, EV/EBITDA and EV/(EBITDA-CAPEX), SK Hynix is ridiculously cheaper than Micron maybe due to the Korean discount but whatever. Cross-sector wise, memory also tends to be cheaper than compute, manufacturing and networking sectors. Now pair that up with SK Hynix's dominance in HBM3/3E, HBM4/4E, I have little doubt about the company's future prospect.
- Korean stocks are known to be significantly more volatile relative to it's asian peers, let alone the US. So I'd be extra cautious to structure investment decisions purely on the price charts.
Everything is squeezed out of my brain, no AI is used so do not criticise my writing. Criticise my analysis, thanks.
Theres various worries cropping up for “tech/AI” (higher borrowing costs for tech, circular risks as deals are inside the sector, more consumers dipping into savings, etc..) but, .. silver lining, IBM is gaining as of now!
I loved reddit for real analysis made by humans
So much AI these days they should put up a filter or detector for this slop
