闪迪（SNDK）上半年涨了超850% 这不是炒作，这是 AI 对存储需求有多真实的直接体现 闪迪的 Q3 营收同比涨了 251%，毛利率达到 78.4%，已经比很多软件公司还高 这个数字让我认真重新审视了一下 下半年的配置思路 ════════════════ ▸ 核心主线没有变：AI基础设施 存储和半导体这条线还在 AI 训练和运行都需要大量内存和存储，闪迪只是其中一个例子 美光（MU）背后的逻辑是一样的，这条线我会继续重点持有 AI 的需求还在往下传导 数据中心耗电量巨大，电力设备、能源这块也在受益 服务器、网络、光纤相关的公司也都值得关注。 大科技这边，英伟达、博通（AVGO）、微软、亚马逊、谷歌、Meta 这些公司，要么是 AI 的核心受益者，要么本身就在大量投入 AI 建设 机构普遍认为，只要回调出现，就是加仓机会。 ━━━━━ ∘ ━━━━━ ▸ 次要方向：分散配置一部分 国防和工业这块，全球局势紧张，各国安全支出在增加，这个逻辑比较稳定 能源和材料，一方面是 AI 带来的电力需求，另一方面是对通胀风险的一种对冲 医疗健康，防御属性比较强，长期逻辑也清晰 ════════════════ ▸ 我自己的仓位参考框架 ╭──────────────────────────╮ AI/科技基础设施 50-60% 能源/电力/材料 15-20% 国防/工业 10-15% 现金/防御 10-15% ╰──────────────────────────╯ 这不是固定配方，是我现在思考配置时的大概比例 每个人的风险承受能力不同，比例要自己调整。 ━━━━━ ★ ━━━━━ ▸ 几个操作上的提醒 回调出现就是机会，追高风险大 7 月份有就业数据、美联储会议（美联储就是决定利率的那个机构）、大科技公司的季报陆续出来，这些都可能带来短期波动，也可能带来买点。 不要把全部资金押在一只股票上 可以考虑半导体 ETF 或者 AI 主题 ETF，分散风险。 杠杆要控制好 高估值的环境下，一旦行情反转，杠杆会让损失放大很多倍。 ──────────────── 下半年的核心逻辑没有变：AI 基础设施带动的美股行情还在延续，只是会更挑剔，更看重基本面 闪迪这种故事还在跑，但要持续跟踪需求和供给的平衡，不能只看涨幅买股票。 以上仅供参考，不构成投资建议。DYOR #美股# #半导体# #SNDK# #MU# #AI产业链# #H2配置#

Beta Updates Surge Engine • Added VLESS Encryption (mlkem768x25519plus), including share-link import and proxy editor controls. • Added VLESS XHTTP transport with stream-one, stream-up and packet-up modes over HTTP/1.1, HTTP/2 or HTTP/3, including VLESS Encryption and Vision. • Reduced memory retained after QUIC downloads on lossy networks. • Improved QUIC upload performance and reduced CPU usage when chained through a proxy's UDP relay. • Fixed established VLESS gRPC, HTTP/2 CONNECT and TrustTunnel connections being incorrectly counted as connection setup failures when they ended with an error. • Fixed WebSocket policies failing to connect when their ALPN list included h2 and the server selected it. • Fixed Tailscale connections staying on a relay after a peer restarted because updated peer information was not applied. Surge iOS • The proxy editor now imports share links for all supported proxy protocols, as well as proxy lines copied from Surge profiles; unsupported settings are reported instead of silently omitted. • Reorganized the proxy editor with an Advanced page that indicates settings in use, and added controls for more protocol, TLS, WireGuard, Tailscale and testing settings. • Fixed Always use CONNECT not being saved for HTTPS policies, and corrected when TLS and Block QUIC settings appear. • Updated list layouts and badges, and added member counts for policy groups in the proxy list. Surge Mac • The proxy editor now imports share links for all supported proxy protocols, as well as proxy lines copied from Surge profiles; unsupported settings are reported instead of silently omitted. • Reorganized the proxy editor with a remembered Show Advanced Settings option and controls for more protocol, TLS, WireGuard and Tailscale settings.

从数据中心建设节奏说说为什么光互联现在进入了业绩爆发期？最早是7月下旬提到光互联业绩兑现空间也很好。8月4号还详细写了一篇看好光互连的逻辑、一周过去多光好像成为了共识。除了之之前聊到的逻辑，再从数据中心建设节奏的角度聊聊： 1、云厂商CapEx节奏与数据中心建设时间线 超大云厂商资本开支大规模提速在25年下半年，看看数据中心建设典型节奏： 1）前期（数月到1年+）：选址、许可、土建、厂房、电力基础设施（变电站、变压器、冷却）。 2）中后期（建设后半年至1年多）：机柜/服务器进场、网络布线、组网调试。AI机柜功率密度极高（单机柜几十到上百kW），需要密集光纤和高速互联。 能看出什么来？ 去年下半年开始的大规模数据中心建设在今年二季度现在正好进入了服务器进场，网络布线、组网调试阶段。时间线就是： 1）2025 H2-2026年初土建/电力推进，2）2026年进入服务器密集部署窗口，光模块需求同步或略提前爆发（因供应链长周期需提前锁定）。 2、AI集群越大对互联的要求越高 GPU/ASIC间参数同步、scale-up（机柜内/跨机柜）、scale-out（集群间）、scale-across（多数据中心）都需要大量高速光模块。传统铜缆在距离、带宽、功耗上受限，光成为刚性需求。单个加速器配比光学连接数上升（从约1:3到1:4.5甚至更高），光在总CapEx中的占比提升也很快。 而且整体还在从从400G/800G向1.6T迁移，单模块价值更高；scale-up场景光学渗透提升。未来NPO到CPO也陆续在落地。 简单说这就是数据中心建设的滞后效应的体现： CapEx公告 → 土建/电力（2025）→ 服务器部署（2026）→ 光模块密集消耗。然后AI集群规模从万卡向十万卡级扩展，进一步放大光学需求。 而这两天热议的“多光空存”，放在当下这个时间节点看、“空存”其实已经不具性价比了，毕竟存储板块已经经过了大幅度调整，调整本身就是释放了风险。个人认为现在看存储还是有空间、只是涨幅最暴力的阶段过去了、不那么easy了，走势也不会像上半年那么丝滑了。 如果存储现在是个复杂题、 光互连可能就是当下的这道简单题了。

Is Ethereum finally taking the driver's seat from Bitcoin? 📉➡️📈 The $ETH / $BTC ratio just surged to a 3-month high of 0.030, driven by a massive +16% monthly performance spread in favor of Ethereum (+24% vs. +8%). The latest KuCoin blog breaks down the fundamental forces behind the momentum shift: 📊 Reclaiming the 200-Day SMA: The cross-rate has officially reclaimed its 200-day Simple Moving Average for the first time since January, signaling a technical trend reversal. 🌊 ETF Flow Flippening: U.S. Spot Ethereum ETFs recorded $103.9M in weekly net inflows—outpacing Spot Bitcoin ETF inflows by a factor of 3-to-1. 🔒 The Supply Vortex: Public treasury accumulation (Bitmine holding ~4.8% of circulating supply), a zero validator exit queue, and 2.5M ETH waiting in the staking entry queue have squeezed spot liquidity. ⚙️ "Glamsterdam" Horizon: Institutional RWA dominance exceeds $17B on Ethereum, with the H2 2026 "Glamsterdam" upgrade set to introduce parallel processing and slash L1 fees by over 70%. Is this just a short-term liquidity rebound or the start of a full-scale market rotation? Read the full technical breakdown here:

Feels bad, -49.4% drawdown this month after the recent crash. My portfolio is mainly AI chokepoints and bottlenecks. In the memory, photonics, robotics, and upstream semis, (on margin) which all tend to be higher beta than others. But reduced leverage recently from the crash. I see a lot of people making fun of the drop or AI names, saying it’s obvious that: - “AI is a bubble” - “memory/kospi is a bubble” - “photonics is a bubble” - “humanoids won’t get anywhere” - “neoclouds will get replaced by hyperscalers like Meta” And a bunch of retail + bots saying “sell everything, it’s never going to recover”. But I have conviction that all these themes are backed by structural revenue growth or technological shifts. And I’ve had similar drawdowns back when there admin threatened global tariffs, before markets pulled off a recovery. I personally have a longer horizon + higher tolerance for volatility than others, to see how this plays out. Especially considering a lot of retail view things on a week to week basis: no, my thesis isn’t wrong yet if I project revenue inflection in H2 2027 and it’s 2026 now. Anyway, feels bad short term just wanted to share anyway for transparency.
