Performance shown reflects the back-tested price return of the indexes. There are frequently material differences between back-tested performance and actual results. Past performance—whether actual or back-tested—is no indication or guarantee of future performance. The indexes were not created, selected, approved, or endorsed by the named individuals (the "Experts") and have no affiliation with the Experts or any social media platform.
