    Here is what I ended up.

     

    .Covar = 
VAR Tabela =
    FILTER(
        SELECTCOLUMNS(
            ALLSELECTED(Base[Date]),
            "LnAsset",  [.ln],
            "LnIBOV", CALCULATE([.ln],Base[Asset]="IBOV")
        ),
        AND (
            NOT( ISBLANK( [LnAsset])),
            NOT ( ISBLANK( [LnIBOV] ))
        )
    ) 
VAR Denom = COUNTROWS(Tabela)-1
VAR Res = SUMX(Tabela, ([LnAsset]-AVERAGEX(Tabela,[LnAsset]))*([LnIBOV]-AVERAGEX(Tabela,[LnIBOV]))/Denom)
RETURN
Res

Greg_Deckler thanks for your answer. I just wanted to add all the values of Result. When I just called Var Result it didnt show the expected value ( -0.0000795701 ). I´m missing the table variable. Just fyi the SUMX(Base, Result) and just Result returned diferent values. I can share the pbix if you like. Thanks again.
