- What is the Diversification Score?
What is the Diversification Score?
The Diversification Score evaluates how effectively you are spreading risk across different types of investments.
The Math behind Diversification Score
There are two main parts of the Diversification score:
Individual Security Allocation (worth 70% of the score): You want to make sure you are not too heavily exposed to a single security
- Max Exposure [Cash] = 10%
- Max Exposure [Stocks / Bonds] = 15%
- Max Exposure [ETFs] = 30%
Investment Type Allocation (worth 30% of score):

You want to make sure you are invested in several Industries (eg. technology, financials, energy, etc.), Geographies (eg. United States, China, Japan, etc.), and Asset Classes (eg. Stocks, Bonds, ETFs, etc.).
Tips to Keep in Mind:
Tip #1: As a professional portfolio manager, holding a large amount of cash generates high opportunity risk (missing out on returns you could have generated). You'll want to invest 90%+ of your entire cash holding.
Tip #2: Use the exposure column to communicate the strength of your beliefs behind each investment.


Performance Goals
You will want to aim for a score of 80+. If you are in a challenge this will earn you a Portfolio Management badge.
