World’s first Fractional Performance Index

Not sure if you saw the news, but last week we announced something very special.

We created the world’s first Fractional Performance Index.

What is the Fractional Performance Index?

This is the very first index that tracks the performance of all IPOs across Rally, Collectable, and Otis since inception, and gives individual results for each platform.

And it’s exclusive to Alternative Assets subscribers.

With Insider, you know we analyze every fractional IPO, giving each one a Yes or No recommendation.

Based on those recommendations, we’ve also launched the Alternative Assets Club Index.

As it turns out, we aren’t just tracking the market, we’re smashing the market.

Since February 1st 2021, we’re beating the Index by 51 points.
