Aggregate method comments draw attention

I think I've gotten a record number of comments regarding this month's newsletter, some of which we'll share in the August edition. One reader encouraged me to transform it into an article, which I hinted that I might do and now have support, so I will pursue this.

I don't know how many vendors calculate their GIPS(R) (Global Investment Performance Standards) composite returns using the aggregate method, but believe that it's quite common. No vendor has reached out, yet, though I would suspect that some might. I wasn't attempting to cause any problems, but the evidence from my analysis does call into question this method's appropriateness.

Please let me know your thoughts, too!
