First off, hats off! to the Brits, or at least to those of their number who voted Leave.
But now what should we do financially speaking? Expect turmoil in the markets. The stock market was down when I checked it a few hours ago. But gold and other precious metals were up. Good news to those of us who had the foresight to buy the stuff, and who held it, even when we could have made a pile by selling. ('Lead' is also a precious metal these days, and not just for the protection of gold.)
Me, I am not doing jack.
Nor should you if you have adhered to sound MavPhil principles of personal finance.
Stay the course! Keep calm, and carry on.
