See how an ETF's price compares to its holdings.
Calculates ETF premiums and discounts, compares funds, and explains sudden moves relative to their holdings.
When to use it
Use for questions about ETF premiums, discounts, arbitrage, convergence, or moves that diverge from underlying holdings.
Give it an ETF premium, comparison, screening, or sudden-move question; it returns calculated results with interpretation and caveats.
Requires Python to run the analysis; the dependency probe uses python3.
