One thing I notice right away is that I wish there was some kind of description or context for some of these custom index things. Like why did the creator decide on this mix? What's the background? Otherwise they are just lists of stocks.
Yes! This was my first thought. Tell me a little about each fund. Even if you have some familiarity with every company in the portfolio, it might not not be immediately obvious why they are being grouped together.
Love this suggestion. We've got lots of plans for helping folks communicate their thesis & decision making. Personally I like the README metaphor, but we also want to facilitate comments & discussions
