I know I will be asked about this so I better put it out there...
Some AutoTracker member's returns are 0.01% different than others with the same allocation.... Why is that?
In regards to the an allocation of 50% C, 50% S for example, some got a daily return of 0.79% and a few got 0.78%. The actual return was +0.785046%.
So, I know it looks off, but it is actually correct on the accounts - It's just a rounding issue and caused by rolling over return from the prior year, and the way the daily figure is derived for each account in the AutoTracker.
The way we figure your daily return is to take your new annual return and subtract the prior day's annual return.
Here is a rough example: If your return was 8.9800% on day 1, and the G-fund was up 0.0043% on the day, your new return is 8.9843%. Rounded that is still 8.9800% which rounds to a gain of 0.00%.
If your return was 8.9842% on day 1, and the G-fund was up 0.0043% on the day, your new return is 8.9858%. Rounded that is still 8.9900%. So you'd see the +0.01%.
So it's correct in the database and calculated to 2 more decimal places, but because of rounding it doesn't look like it rounded and displayed on the standing page.
I hope that makes sense.
