Here's a new chart.
It shows the historical NAV of all Nu funds both on exchange and in BTC and US-NBT wallets used for;liquidity focused shareholder funds.
The history of the balances on exchanges goes back about a month. the historical balances of the addresses only go back a few days.
Each point on the chart uses the balance (on the exchange or at the address) at that point in time. BTC prices are converted to USD using the CoinMarketCap price at that point in time too.
I've added buttons to change the time scale to allow for zooming in on the current NAV. Future work will be to allow for a time range to be enetered to zoom in on that time range instead.
Comments and Constructive Criticism welcome.
