3 ZXData Robustness Score is an internally developed metric to assign confidence levels to the underlying data used in constructing ZXData output metrics. The ZXData Robustness Score is calculated on a scale of 1 to 10 for each company, based on the number of executed trades, number of buy and sell orders submitted to ZX and skewness of the order book.
4 ZX Index Value is an internally developed metric that reflects secondary values for private companies using an algorithmic approach based on the values sourced from ZX and ZXData partners. The algorithm used to calculate ZX Index Values incorporates both executed transaction values and bid and ask pricing.

In August, 19% of companies with ZX Index Values showed a difference of 10% or less compared to Fund Marks, and 40% of companies with ZX Index Values showed a difference of 20% or less compared to Fund Marks. Among the companies, Neuralink, Ayar Labs and Celonis had the highest positive variance in reported marks versus ZX Index Values. Dataminr, Groq and SambaNova had the highest negative variance in reported marks versus ZX Index Values.

5 Normalized Standard Deviation is used to express the measure of spread across reported marks and allows for comparison between companies independent of their price per share based on a dollar-weighted average.

This period Roofstock ($3.89 - $18.17) saw the highest share price variance across funds followed by VAST Data ($56.71 - $267.34) and FLEXE ($2.92 - $17.65).

Disclaimer

This report is based on data reported by 300+ funds and $110+ billion of value. Many holders of private company shares do not report their holding values and are thus not included in this report’s dataset.

This report does not constitute investment advice or a "research report" as defined by FINRA Rules.

The “ZX Index Value” is derived by applying proprietary weightings to the order flow data collected for the stated period (both bids and asks), based on the order type (firm order or indication of interest) and whether the order has been executed, with greater weight given to more recent orders.
