Do you know if Stan's trading results were officially confirmed or published somewhere? Like a trading contest (USIC) or something?

I wonder what rate of return he had in his prime years (or later) but I cannot find any clue over the internet.

Stan likely made the bulk of his money from the trading service. He was making millions from the PTC newsletter in 1983 (15,000+ subscribers at $250 a year), and then after the book in 1988 he was encouraged to start an institutional service called the global trend alert (GTA) which made him a whole lot richer, which still runs today 31 years later at $60k a year. So I don't think you'll ever see his trading results, as he's never needed to as the business has made his fortune.
