Fund Z Statistic!

Carl Reid shared this idea 9 years ago
Under Consideration

"The z-statistic is used to measure a fund's discount/premium relative to its average discount/premium. Z = (Current Discount - Average Discount) / Standard Deviation of the Discount. A negative z-score indicates the current discount is lower than the average, and vice versa. The magnitude suggests whether the z-statistic is significant: For instance, a z-statistic of +2 or greater would be expected to occur less than 2.25% of the time."


Morningstar uses a 1 year and 3 year lookback period for the average and standard deviation.


This seems like a possibility because of historical NAV. Just had a pro request for it, and 2/3 AEs that I asked have said they have heard it before. It will help with obtaining and kretaining a select number of M* users.

So Morningstar just added this to the API and we may need to get contract approval but should be here:


Performance Data/Trailing Month End Performance/ZStatistics
