Portfolio data refers to the information collected and tracked about startups you have invested in, such as their financial performance, growth, valuation, exit potential, and impact. This data can be used to monitor the health and progress of your portfolio companies, identify risks and opportunities, and assess your return on investment. Internal rate of return (IRR), multiple of invested capital (MOIC), net present value (NPV), cash-on-cash return (CoC), and portfolio diversity are all metrics you can use to measure your portfolio's success. IRR measures the annualized rate of return earned from an investment over a specific period of time. MOIC is the ratio of total value to initial investment. NPV is the difference between present value of investment and present value of cash outflows. CoC is the ratio of cash received from investment to cash invested. Lastly, portfolio diversity is the degree to which your portfolio is diversified across sectors, stages, geographies, and types of startups.
