Further more, personally, I came to Zerodha so that I can get a complete centralisation of my investment decisions. This includes,
Research: qualitative/news etc and quantitative/risk measures and performance analysis
Invest: Buy/sell etc
Manage: Look after the portfolio, create alerts etc
Reporting and consolidation: Either for audit or tax purposes.
The biggest thing I see missing, atleast for Coin, is the research bit. Websites like www.thefundoo.com try to do this well, but my primary motive of keeping everything at one place is sort of defeated if I have to switch between these applications.
What would be great, for above average - advanced non-stock investors, is the ability to do this compare and contrast of fund and its performance with some well understood measures. I agree with the above point that ratings are not helpful 99% of the times, but these comparative analysis across different dimensions is certainly valuable, is what I feel. Simply put, I’d even be willing to pay a small yearly amount for such a feature.
