Just a note to alert those concerned: PRIDX
Using (premium!) Portfolio Manager, Morningstar STILL, at this hour, shows a loss per share today, 19th January, of 3 cents. But look instead at the "snapshot" view of the fund, and you'll see that the actual daily performance was +1.75%.
(The lovely geniuses in charge stopped offering hard-currency amounts in that space, long ago. Percentage is offered, only.) .....MARKETWATCH shows the per share rise in actual dollars and cents to be +$1.61. And that info is available FOR FREE.
