New Securities Finance demand sentiment data, presented at the transaction level, enables users to track short position profitability and assess squeeze risks. The new Securities Finance inventory data delivers transparency into lending supply at the underlying fund level, providing unique insights into institutional fund flows and long positioning. Securities lending data can also be combined with ETF composition data to generate novel factor exposures for ETFs, whereby short sentiment at the ETF level can be calculated using a bottom-up approach. Aggregating short sentiment data at the ETF level can be used for systematic ETF portfolio construction. Together, these advances demonstrate how evolving datasets are driving new opportunities for quantitative strategies - Mark Klein, Executive Director, Head of Business Development - Equity Analytics Products S&P Global Market Intelligence.
