What's the Basis of Your Plan?

What is the best way to go from point A to point B? Who better to ask than those who have gone before. At Zunna, we believe that experience is the best guide for the future. The investment software and services we sell are based on this premise. We don't predict futures. We study what has gone before, to see what worked, what didn't, and why.

No two investors are the same. Our software helps each investor find efficient investment strategies and optimal asset allocations that fit specific needs. Our focus is on long-term financial planning and investment strategy validation. Our emphasis is spending policies for retirees and charitable organizations. If you want superior investment software and research for financial planning and retirement planning you have come to the right place.

Our flagship product, WATS (pronounced watts) has received high praise from industry experts. It incorporates the methodology used in The Trinity Study and elaborates on it, including a new technology for portfolio optimization. WATS has tools specific to retirement planning and spending policies, but is well-suited for studying a variety of investment scenarios. WATS also lets you surf efficient frontiers, which tests portfolio efficiency using rolling periods.

The basis of WATS is a powerful calculation engine that runs investment scenarios through historical periods just as if you had lived during those periods. After running every available historical period WATS reports on historical success rate as well as worst-case, average-case, best-case, standard deviation and much more.

WATS printed output is intended to help advisors find workable solutions for their clients. For samples please click here.
