This chimes with my experience. I tell students that they should take as many finance-related courses as possible, including advanced courses in the business school. Math-anxious law students normally shy away from classes like these, only to find that they are expected to understand what a collateralized debt obligation or credit default swap is on the first day of practice. And, unlike the case of, say, antitrust, a good understanding of finance is not something one can pick up from practice. One might learn to fake it, but one needs a deep understanding. Every other big case these days seems to have a large finance component, and lawyers who are comfortable with finance can contribute more than those who aren’t.
