Launches India’s First Private Market Index Private Market Index

One of India’s leading online unlisted securities portal has launched India’s first Private Market Index known as StocX Private Market Index (SPMI).

GURGAON, HARYANA, INDIA, December 8, 2022 / — Until now, there was no way to track the price movements of privately traded securities (i.e the stocks of the companies that are not yet listed in the stock market). The biggest challenge in constructing such an index is availability of the price. The unlisted market does not have transparent pricing and therefore price may vary from portal to portal and it is quite difficult to compile the price movements and build an index. claims to achieve this by using the concepts of indexing & basic statistics. built the StocX Private Market Index using a unique methodology known as “Change Percentage.” The index is computed using 1000 as the base value as on 01st of Jan 2022. Daily prices from various dealers such as and other marketplaces are collected and percent change from previous day price is computed. The prices of the shares that are not available for the day or for the previous period are discarded. For the remaining shares wherein the price data is available for both the days, a percentage change is calculated. The average of this percentage change is then used for computing the change in index value.
The index will track prices of more than 30+ companies actively traded in the unlisted market and provide analysis and trends through data analytics.

The current index value stands at 1067 which means that from the 1st January, 2022 to 30th November 2022, the average price of the securities have increased by 6.7%. The index will be updated on a daily basis.
The company claims that the index is free of typical biases that are inherent in most of the public market indexes like the selection and survivor bias as it automatically includes all companies whose prices are available for 2 consecutive days and excludes all the companies whose prices are not available. Which means that the index will keep adding and removing companies based on price availability and since it is taking only the percentage of change into consideration, the impact is that overall an investor gets a very good picture of how his portfolio would have done if he had invested in unlisted securities.

The initial report throws some interesting insights as follows:
The volatility of the index has been very low compared to the public markets. As can be observed from the graph below, the maximum and minimum hovers around 10%-15% from the mean. Interestingly the private market has given 6.7% return from 1st jan 2022 compared to 6% in Nifty.
