Very interesting that this works. And great to see experiments like this which open their methodology.

Looking at the status page, https://www.gptinvestor.co/the-gpt-investor/

- GPT version has been better than benchmark 8 times, while the benchmark won 11 times.

- GPT return was negative in 5 experiments and 0 times for benchmark.

- GPT invests in a quite small selection of 1 or 3 stocks (mostly tech).

- The GPT outperformance comes from one 100% bet on NVIDIA that is still ongoing (+140%).

I like my blood pressure a bit more steady to start just yet with this method.
