I just learned why our portfolio values in Quicken are often different by a small amount from what the broker's websites says they are - at night when the markets are closed.
I used to think after-hours trading must have something to do with it -- nope, it's simpler and stupider than that:
" The
closing price of a stock is the price at which the share closes at the end of trading hours of the stock market. It is not to be confused with the
last price which is the final price at which the stock was traded before the markets closed. "
These sound to me like the same thing but apparently they are not. Here's how this played out for AAPL as of end of trading (4PM) on 2-9-2023:
Market "closing price" reflected almost everywhere (e.g. CNBC, Yahoo) was $150.87
BUT QUICKEN, and TD Ameritrade, Fidelity, et al use the "last price" of $150.64
BUT BUT Schwab, Morgan Stanley, E*Trade, et al use the "closing price" of $150.87
Go figure... if I'm not getting this right someone please educate me
