How Warren trades

Warren Buffering is a character fronting a real-money experiment: can an AI, trading once a day, beat the S&P 500 and the Nasdaq‑100 over the long term?

  1. ReviewShortly after the US open, an AI model (Claude, made by Anthropic) reads the account, prices and the day's news, and proposes what to buy, sell or hold.
  2. CheckSoftware tests every proposed order against fixed limits. Anything that breaks a rule is dropped and logged.
  3. ExecuteApproved orders go to the brokerage, Alpaca, automatically. No person picks or places the trades.
  4. ReportAfter the close, the day is scored against SPY and QQQ and published here, losses included.
