Connect your AI client via MCP
Endpoint (paste into an MCP client — anonymous, free, no key)
https://mcp.koalcheck.com/mcp
Or copy this and send it to your AI to set it up:

Add the "koalcheck" MCP server to my client and connect. It is a remote Streamable-HTTP server at https://mcp.koalcheck.com/mcp — connect anonymously, no API key or login needed (the free tools work right away). If my client supports a remote/HTTP MCP server directly, just use that URL. If my client config only accepts a local command (e.g. Claude Desktop's mcpServers, which rejects a bare "url"), bridge it with command "npx" and args ["-y","mcp-remote","https://mcp.koalcheck.com/mcp"]. Then tell me to fully restart the client, and list the koalcheck tools you can call. It provides US-equity research tools built on an analyst track-record engine (who has actually been right, priced vs SPY, cross-checked with SEC & FINRA).

《CPO杀穿AI供应链》 今天玩了一天,傻哥把前几天学些Serenity的投资笔记分享给大家: 先看老黄的原话: "CPO 不是'可选增强'——是 AI 数据中心的'结构性必需'" "百万 GPU 集群必须用 CPO,否则物理上不可能" CPO是AI供应链的一大趋势: 简单来说,CPO 就是共封装光学。现在的笨办法是,AI 芯片先走一段长铜线,连到外插的光模块,再接光纤。电转光全靠外置模块,费电又占地。而未来的 CPO 黑科技是直接把光学引擎塞到 AI 芯片旁边,距离只有几毫米。英伟达和 Marvell 都在往死里推这个技术,预计 2027 到 2028 年就会大规模商用。 为什么说 CPO 是颠覆性的,看这四个核心数字就懂了。首先功耗直降三点五倍。一百万张 GPU 如果用传统光模块,光网络就要吃掉一百八十兆瓦的电,换成 CPO 能直接压到五十兆瓦。其次带宽能飙升一百倍。再者网络可靠性提升十倍。最后是市场这块大蛋糕,到 2036 年,市场规模能高达两百亿美金。 CPO 的供应链有 5 个 chokepoint(瓶颈环节): 1. 衬底(Substrate)→ 谁做?$AXTI、$SOI(垄断) 2. 光源(Light Source)→ 谁做?$SIVE、$AAOI、$POET 3. 光学引擎(Optical Engine)→ Marvell、Coherent 4. 测试 → $AEHR 5. ASIC → NVDA、Marvell、Broadcom 策略点评: 1、小盘股很容易meme化,形成类似币圈那样的收割链条 2、所有标的押同一个故事,过于集中了。 如果CPO的商用受阻,会全面崩掉。 3、目前看收益很高的。
