Yeah, totally. If you're talking professionally, it helped me make the transition from a pure dev role at a financial firm to a quantitative front-end role. If you're talking about personal projects, it helps a lot if you want to develop your own quantitative trading strategies. I've been using https://www.quantopian.com/ to develop strategies and am currently trying to get on the board for their contest https://www.quantopian.com/contest. I'm hoping to try and get an allocation from them. They currently manage somewhere around a couple hundred millions dollars and allocate money to various algorithms that win the context, allowing you to net a percentage of profits of the strategy.
