The indices are extended but that is not new or news with late day runs the last two sessions and most sessions since the March low a reflection of improved market confidence. In conjunction with this momentum there is a propensity for the indices to reach new weekly extremes on Friday's. Initial short term resistance is at SPX 838/839 (62% retrace of Jan-Mar) with a minor barrier at 846. The market has become extended but there often is at least some positive seasonal bias near the end/start of the month/quarter and this could be more prevalent given the exceptional reversal this month.
