Forge Global Holdings, a private securities marketplace, has expanded its offering of private market data products and solutions for institutional asset managers, with the launch of the Forge Private Market Index, a benchmark for actively traded private companies that enables investors to better measure their investment returns and gain insights on late-stage, venture-backed companies.

The Forge Private Market Index is comprised of the 75 most actively traded companies on the San Francisco company’s exchange. Every quarter, based on which companies have become the most actively traded, Forge adds or subtracts companies from the index.

The index, which is priced daily and updated weekly, includes US domiciled companies that have raised at least one round of primary funding and have higher relative secondary liquidity in the past 12 months, thereby reflecting the actively traded segment of the private market rather than over-emphasizing primary valuations, which bring less continuous pricing and liquidity information.

“As more investors turn to the private markets for new sources of return and diversification, they need the tools that they rely on when investing in other asset classes,” said Forge CEO Kelly Rodriques.

The performance of the Forge Private Market Index does not represent the performance of any actual investment, as the index is not investable, but rather reflects the hypothetical growth of a $10,000 investment in a basket of securities based on the Index.
