So Harry and Meghan are spinning themselves off from The Family Firm. The Economist provides the stock market analysis

Harry and Meghan’s move was announced without consultation with the group’s management, but may have been encouraged by developments within it. The stock price has tumbled recently, as a result of missteps by Prince Andrew, who has now been fired. Prince Charles—who will take over the top job in the not-too-distant future—has hinted that he plans to cut costs and slim down its operations as part of a broader restructuring. Rather than wait for that shake-up, Harry, who knew he was unlikely ever to get the top job, has now decided to cut loose.

This separation has the advantage of strategic clarity, and is likely to unlock value, given that the Harry and Meghan brand was widely perceived to be undervalued. The new entity will now have more freedom to diverge from the positioning of the parent group and to tap overseas markets. The couple say they plan to divide their time between Britain and North America.
