Do you have examples of proprietary strategies used by tech/quant funds like 2 Sigma, Cubist, Citadel, Headlands ?

Of course, this information is difficult to obtain because the strategies are proprietary.

But I highly doubt that a given strategy can run for 10 years or more. Are there resources that compile proprietary strategies that ran well ten years ago ? Is it possible to find a website, a blog or anything else that show some examples of successful prop strategies ?

I am not interested with “abstract” and general stuff like “They use pair trading, meaning they buy Chevron and sell Shell” or “correlation is mean reverting so we focus on buying under valuated spreads”. I ask for precise description.

Thanks, in advance.
