James Packer must think Crown Resorts shares are undervalued based on recent purchases by his holdco. Although on a smaller scale, Steve Wynn has also bought a small number more of Wynn Resorts shares. I guess these billionaires figure Macau is due for a turn of fortune. They will probably be right in the long run.
