The Complete Guide to Using AI to Spot Undervalued AI Stocks
How I set up Claude Fable 5 for stock research , and which of my 3 skills actually need it .
The model they tried to ban is back. Here’s how I point it at stocks.
For about two and a half weeks, the most capable AI model you could legally touch simply… vanished. On June 12, 2026, the U.S. Commerce Department ordered Anthropic to suspend Claude Fable 5 (and its locked-down sibling, Mythos 5). The trigger was a jailbreak that Amazon’s researchers found , a prompt that got the model to flag software flaws and, in one case, write code showing how one could be abused. Because the order applied to any foreign national and Anthropic couldn’t check every user’s passport in real time, they pulled the plug for everyone.
Then, on June 30, the controls were lifted. Fable 5 came back online on July 1 across Claude.ai, Claude Code, and Cowork.
I’m not going to tell you it was “taken out because it’s too powerful and might shock the world.” That’s the internet’s version. The real version is more useful to you as an investor: the single most capable model Anthropic has ever released to the public was considered serious enough that a government reached for emergency export controls — and it’s now sitting in the same app you already use. That’s the part worth paying attention to.
So this week is a hands-on one. I’ll show you exactly how I set Fable up for stock research, what it’s genuinely better at, and — the part most people get wrong — which of my three skills actually need it, and which ones you’d be silly to waste it on.
Let’s get into it.
