Csquare is trading at $17.26, up 8.32% after hours, with no clear company-specific catalyst identified. - Csquare had previously announced its CEO would speak at a September 30 investor conference; that earlier notice does not establish a reason for the move. - Supplied index moves were mixed and modest and do not clearly explain the gain. Reliable reporting cited broader pressure from rising oil prices and Treasury yields, not a broad-market rally.
