(reply to a misconstrual of the original question removed) Okay, if you are asking about right hand fingerings of a six string e minor chord, one question I have is, how would the answer be contingent upon the chord being an e minor? If it's a six string chord, then the question simply goes to the sounding of six strings, no matter what chord it is, doesn't it?
Anyway, what would affect the answer would be the written texture, or the texture you want to produce, in any instance. If written (pr improvised) as a simultaneity on one note stem then probably a single upward stroke with the thumb, or the index finger, or a rasgeado with multiple fingers would do. If a rolled chord is indicated or desired, then most likely would be an upward roll using the thumb successively on the sixth, fifth and fourth strings, and I-M-A on the upper strings. It is enabling to the thumb rest-stroke aspect and the thumb-finger transition to play from a high wrist position with the wrist kept still.
In various arpeggiated textures, one may begin with the basic thumb-on-bass, I-M-A on 3rd-2nd-1st string allocations, but there are so many possible arpegggiated textures that just about any consecutive re-ordering of string-finger assignment may arise. In other words, the question is too general to admit of a meaningful response. Do you have some specific instances you are wondering about?
