Net asset value (NAV) is a fund’s per-share value after subtracting liabilities from its assets. Mutual funds trade once daily at the price calculated after market close. section 1.2.4
For pooled investments, pricing fields describe the underlying asset differently from individual-stock metrics. For ETFs, navPrice represents current market value, while yield abstracts income from dividends and interest payments. section 6.5.2
Monitoring ETF values
A portfolio monitor can filter ETF positions, retrieve financial data, and merge navPrice and yield into a DataFrame before exporting the results. section 6.5.2
