The Affordable Way to Take Your Firm to the Next Level

GIPS-compliance solutions often cost thousands of dollars, do far more than you need, and require a staff to maintain.  Easy ROR Pro is the simple solution.  Only external cash flows (balances, deposits and withdrawals) for your clients are needed to generate accurate, detailed, GIPS-compliant reports.1  Provide returns before and after tax and gross or net of fees, with monthly, quarterly, yearly, or cascading periods, cumulative period results, and many other options.

Use GIPS Time-Weighted ROR calculation methods,
including Daily Valuation and geometrically-linked IRR or Modified Dietz, as well as calculation of composite performance and dispersion for portfolio groups using asset-weighted, asset-plus-cash-flow, or aggregate methods.

The global standard for performance reporting.
GIPS® is the recognized reporting standard administered by the CFA Institute.  If you're a professional, offering GIPS-compliant performance gives you a significant competitive advantage.  In fact, prospective clients will increasingly expect your practice to be GIPS-compliant in the coming years.  Easy ROR Pro provides the necessary methods to meet the latest standards.1

Compare performance to tailored benchmarks.
Easy ROR Pro provides comparison of investment returns with your choice of indexes, or your own tailored benchmarks blending any indexes or securities.  Benchmark comparisons can be either direct or "as-invested" (as if cash flows were made to the benchmark as they were made to the portfolio).  Easy ROR Pro automatically downloads and calculates benchmark rate of return over the applicable periods.2

Measure portfolio Risk/Reward and Gain/Loss.
Provide your clients revealing metrics like Beta, Volatility, R-Squared and Sharpe Ratio, and show them their periodic and cumulative gain/loss.

Additional Rate of Return methods...
Easy ROR Pro also calculates MIRR (Modified IRR) for capital investment projects, and Least Squares ROR and Rolling Period Average ROR for long-term planning.

Import data from text files.
Manual data entry is fast and easy because so little data is needed, but for numerous portfolios or historical records you can also upload data from text file(s) using your own user-defined file descriptions.
