韩国贸易协会数据显示HBM出口均价7月达76.13美元创历史新高，三星与SK海力士签署长期供货协议并加速扩产
HBM涨价叙事自2026年7月起已被机构广泛覆盖（高盛闭门会7/30讨论DRAM超级周期与HBM4定价跳涨130-150%、404K报告8/5系统分析HBM涨价与LTA重估），本次KITA月度出口数据只是确认已知趋势而非新增催化。直接标的三星电子和SK海力士均处于13周持续下行趋势（指数73-74），我们在两股上的历史胜率仅24-26%、中位收益为负。A股HBM概念股（香农芯创20日+17.4%、雅克科技8/27单日+6.42%）已在交易该主题。所有主要市场（韩、A、港）均已收盘，美股盘前。超大市值标的的软催化无增量金额，不满足ENTER条件。

结论摘要
韩国贸易协会7月数据显示HBM出口均价76.13美元创新高（环比+9.5%），传统DRAM环比+24.3%。但HBM涨价趋势自Q2起已被市场广泛认知：高盛7/30闭门会讨论DRAM超级周期、404K 8/5报告系统分析LTA与HBM定价重估。直接标的三星（市值约1707万亿韩元）和SK海力士（约1188万亿韩元）均处于13周下行通道，且我们在两股上的历史决策胜率仅24-26%。A股HBM供应链（雅克科技、香农芯创等）已在交易该主题。出口总额实际下降20.4%（量降价升），进一步削弱了'量价齐升'的叙事。综合判断：已知趋势的月度确认，无增量预期差，所有候选均不具备正期望短线交易机会。

关键理由
- HBM出口均价76.13美元创新高确认AI存储需求强劲，但趋势自Q2已被机构充分覆盖
- 三星与SK海力士签署LTA并考虑扩产（平泽代工转存储、日本合资厂），属于战略意向而非确认订单
- 出口总额环比下降20.4%（出货量降27.3%），量缩价升格局下总收入并未增长
主要风险
- HBM涨价趋势若持续超预期（如HBM4良率突破或新客户LTA），可能产生后续催化，但当前数据点本身不构成交易信号
- 三星代工转存储若正式确认，可能改变代工竞争格局，但目前仅为'考虑'阶段

Memory chip prices are surging again as sixth-generation high-bandwidth memory (HBM4) begins shipping in volume for global tech giants' artificial intelligence data centers. Prices for both HBM and conventional DRAM jumped after Samsung Electronics and SK hynix signed a series of long-term agreements (LTAs) with big tech customers.
The average export price per HBM unit reached $76.13 at the end of July, up 9.5% from the previous month and topping $70 for the first time, according to the Korea International Trade Association on the 31st. Export value fell 20.4% to $10.09 billion (about 13.81 trillion won) from $12.68 billion in June, but shipment volume dropped 27.3% to 132.47 million units, pushing unit prices higher.
HBM prices have climbed steeply alongside mass production of HBM4, which will be used in Nvidia's next-generation AI accelerator, Vera Rubin. The average HBM export price rose about 47% to $60.22 in the second quarter, when HBM4 shipments began, from $40.94 in the first quarter. As output of HBM4 — built by stacking DRAM chips — expands, conventional DRAM has also grown scarce, with the average DRAM export price jumping 24.3% to $22.90 in July.
Samsung Electronics (005930.KS) and SK hynix (000660.KS) are accelerating plans to expand supply, converting production lines and seeking new manufacturing sites to meet surging memory demand. Samsung Electronics is considering converting foundry lines at its Pyeongtaek campus into memory production facilities.
SK Group Chairman Chey Tae-won, attending a meeting of Korea-Japan chamber of commerce leaders in Sendai, Japan, said the same day that SK hynix is considering building a joint-venture chip plant in Japan to expand capacity. SK is also weighing acquisitions of Japanese semiconductor materials and equipment makers, according to sources.
"Semiconductors are being exported as soon as they are produced," said Do Won-bin, a senior researcher at the Korea International Trade Association. "Production capacity cannot be increased quickly, so unit prices have no choice but to rise for the time being."
