The market effect of the current Mars-Pluto square (red line) is tracking the historical mean and medians fairly closely. Based on a starting point 18 days before the exact alignment, as of May 28 (three days after the square alignment) the S&P 500 has risen 2.04%, which is just slightly more than the mean (1.78%) and median (1.74%).
