I made this dashboard using data from RobinTrack to create a hypothetical portfolio based on Robinhood user holding data, and compare its performance to a standard S&P 500 market index. I found that Robinhood users underperformed the market by an average of 4% over the last year, however this is partially due to lower volatility in their investments. Let me know if you have any suggestions on how to improve this data!
