Luminis Advisors, LLC (Luminis) brings clarity to the Impact Investment Ecosystem.
The Impact Investment market just crossed the USD 1 trillion* milestone. How much of this money is having a real impact? How are investments performing relative to benchmarks? How much risk are you taking and is this in-line with your own risk appetite and performance expectations? Which asset managers align with your values and impact goals?
At Luminis, we help our clients answer these hard questions by providing relevant and timely risk analysis, and evaluating the social performance of their investment portfolios. We created a robust and highly adaptable methodology to suit the widest range of impact investors, from financial performance-first to impact-only. This methodology evaluates impact funds by their four most fundamental tenets – namely, Performance, Risk, Social and Management / governance (PRSM™). Constantly adapted over the last decade to match emerging trends and the evolving landscape of the Impact Investment sector, our trademarked PRSM™ methodology can be easily tailored to your specific goals and objectives, with the breadth and depth of coverage to guide all types of investors.
* The Global Impact Investing Network (GIIN) estimates the size of the worldwide impact investing market to be USD 1.16 trillion
