In-depth AI stock research, graded in public.
For every US stock we cover, Claude Opus reads the company's filings, releases, news and analyst moves and writes a full research note: the thesis, the sourced case for and against, the catalysts ahead and the price that would prove it wrong. A public model portfolio, decided by Claude, runs on the research, and every pick is graded against the S&P 500.

Today's market read
Saturday, 10 October 2026
Neutral
The market regime ended the week at neutral, the close-of-day read from the last trading session, up from the prior risk-off call. The index is strong and the average stock is not. SPY, the exchange-traded fund that tracks the S&P 500, closed at 778.51, which is 7.1% above its 200-day exponential moving average (EMA) of 727.17. Only 398 of 978 names closed…
Common questions
FrontierPicks, in plain terms.
- What is FrontierPicks?
- FrontierPicks is free, in-depth stock research written by Anthropic's Claude Opus, one of the most capable AI models. It covers 225 US stocks, each with a full research note built from the company's filings, releases, news and analyst moves: the thesis, the case for and against, the catalysts ahead and the price that would prove the call wrong. It also runs a public model portfolio. 147 stocks are re-read every trading day: every stock in the portfolio or with an open pick, plus those in accelerating themes, reporting soon or moving sharply. The other 78 are re-read on a rolling cycle, and none is more than 6 sessions old.
- How do you keep score?
- Every medium-or-higher conviction call is a pick. It opens at the closing price on the day we publish it and closes when it breaks its kill line, when conviction is cut, or after three months. It counts as a win only if it beat the S&P 500 over the same days. The rule was fixed on 1 October 2026, before any pick had an outcome, and every pick stays on the scoreboard.
- What does the portfolio hold?
- The portfolio holds 14 stocks today. The portfolio page lists each one with its entry date and return, every closed trade, and the portfolio against the S&P 500.
- What is the market doing right now?
- As of 9 October 2026, the US market regime is neutral, set by fixed rules from the S&P 500's trend, market breadth and volatility. The macro page has the detail and the journal has the daily history.
- Is this investment advice?
- No. We publish educational research under the EU and BaFin framework. It shows how the model reads the market; the decision is always yours.
- Does it cost anything?
- No. There is no subscription, newsletter or affiliate link, and nothing to sign up for.
