You can buy education. You can buy access, but you cannot buy a mathematical “system” that will work.

There are exceptions to every rule.

GS is a multibillion dollar company, and 1000s of people buy or create automatic mathematical trading systems every month.

Best of luck and congrats to those that make tons.

Andy, it's my understanding that Goldman Sachs hedge funds (the ones that are based on absolute returns, not relative returns) drove a $12.5 Billion fund down to $2.5 Billion in 2009. Oh, and their quants wizards quit when their compensations were changed to become contingent upon results.

There are dozens of automatic trading systems that outperformed the GS discretionary trading megalomaniacs (the ilk that fell into the same trap as Long Term Capital Management – all brains and no common sense).

I'm not sure who you're (sarcastically/jokingly) congratulating…but I don't care if Goldman HAS invented my system… My Sony is outperforming the S&P by ~8.5% YTD net of fees, with a lower standard deviation than the index itself, sans leverage. And it's only made like ~16 executions.
