Do you have serious infrastructure or found something in a niche market? If it's infra, how much did you invest in it?
In general, these sorts of things involve either very niche markets or serious infrastructure investments. I have a strategy that has been posting 75-80% ROC with good Sharpe. Very capacity constrained. So no, I would never share anything about it.
PS. Last I checked, you can't eat %s, so total $ capacity is more important then ROC IMHO
