So, finally, the real reason for this post! Does anyone know of any better sources of information on the “possible” change in price of a mutual fund after the market close?
Assuming you mean NAV= Price
Investopedia said:Net asset value (NAV) represents a fund's per share market value. This is the price at which investors buy ("bid price") fund shares from a fund company and sell them ("redemption price") to a fund company. It is derived by dividing the total value of all the cash and securities in a fund's portfolio, less any liabilities, by the number of shares outstanding. An NAV computation is undertaken once at the end of each trading day based on the closing market prices of the portfolio's securities.
At a basic question level, there can be no change given the definitions.
Reading more into your question, I will respond with a question. Are you looking for arbitrage opportunities? I would assume the mutual fund companies would not appreciate "attempted arbitrage".
