Mitsui Sumitomo Insurance, already owning 10% of $WRB, just went big again! They bought 879,573 shares at $70.53, spending around $62M. Combined with their earlier $42.5M buy, that’s over $100M invested in a short time. The coolest part? They didn’t wait for a dip, they bought more at higher prices. Shows some serious confidence. Just sharing for tracking and discussion no predictions here, but definitely a move worth watching!
