We provide a new theory for nodewise regression when the residuals from fitted factor model are used. apply our results to analysis of consistency Sharpe Ratio estimators there many assets in portfolio. allow an increasing number as well time observations Since is not feasible due unknown nature idiosyncratic errors, we feasible-residual-based estimate precision matrix errors which consistent e...
