Thanks for your reply. I use Mint too. I'm brand new to investing anything outside of 401k and I _know_ that I'm watching things too closely but I'm a data analyst by trade so it's hard not to do so. I'm not acting on any fluctuations. This is merely to satisfy my curiosity. In the grand scheme of things, it really doesn't matter, but I'd just like to see how things are going at a glance on my My Yahoo! homepage that I have customized with various other RSS feeds, weather, etc.
I'm not sure why there's not an easier way to import data into Yahoo and why there's not an easy way to export data out of Betterment. I'm probably just overlooking the obvious.
