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).

好公司不等于好股票,在美股尤其如此。 其实面对一个百亿市值级别公司,该想的问题不要只是涨到千亿,自己能赚多少钱。 更应该问,这家公司为什么只是一个百亿级别,而非千亿?如果要达到千亿,需要满足哪些条件? TAM 和 PE 是两个重要指标。决定了一个股票当前有没有高估,更决定了这个股票是短线炒概念,还是可以拿长线看增长。 TAM(Total Addressable Market)是这家公司能触达的总市场有多大,就是市值天花板。 比如机构基于 2027年全球 HBM 市场规模将达到 720 亿美元,AI 服务器的电源 IC 市场规模将达到 26 亿至 33 亿美元。 720亿相较于33亿,是二十倍的差距。所以,作为 HBM 三寡头之一的美光 $MU ,可以到万亿市值,而在高性能 AI 服务器电源管理 IC 领域拥有极高市场份额的供应商 Monolithic Power 市值 769亿。 在这个前提下,市场占有率决定了自己市值的实际情况。 当然 TAM 也可以扩张,但扩张不是无限的,尤其向下游,自己既作为供应商又作为竞争者,很容易引发现有客户信任危机,得不偿失。 然后是市盈率 PE,经典 OG 指标了属于是。PE 会告诉你,市场当前如何看待这个股票,是当做成低增速企业,还是高增长的公司,还是作为不可或缺的 AI 基础设施。 另外,高 PE 实际也暗含了条件,或者说代价。 也就是当前市场股价,是隐含了哪些预期的前提下达成的。一旦产能爬坡过程中出现问题,或者下游 CapEx 资本开支收缩,再或者管理层在财报中的承诺没有兑现。 当股价回归行业平均 PE 时,较当前要下杀多大的比例。
