Well you see, Exchange Traded Funds (or ETFs) are a lot like mutual funds but they're traded actively on stock exchanges like stocks. Because they're traded like stocks, they have to open their books and let investors know what they're holding not just once a quarter like mutual funds, but all the time. Since fund managers don't generally want the whole world to see exactly what they're holding, so they can build and maintain an advantage over other fund managers, ETFs have so far been tied to different indexes that pre-define a large group of stocks in a sector or market.
This first actively managed ETF is therefore doing something never been tried before -- actively managing a fund with open books so everybody knows what the fund is holding and when it's trading. They've essentially 'hacked' together a mutual fund that trades like a stock so the symbol HAX is ironically appropriate...
I warned you...
