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.

This is quite interesting.  $250 a year was not trival in 1983 and GTA at $60k a year is not trivial, though perhaps in the finance industry things are easier to approve than elsewhere.  So without trading results being available his reputation and the value people found/find from PTC and GTA is still sufficient to sell subscriptions.
