Utilization in the Securities Lending Market

Utilization Metrics

Utilization is defined as loaned shares divided by available shares in the securities lending market, expressed as a percentage. The Utilization metric on TWS is not specific to us. It is based on industrywide data provided by a securities finance data vendor. The metric is not conclusive however, as not every lender reports their Utilization to the vendor. In addition, although the source is believed to be reliable, we do not warrant its accuracy.

Generally, Utilization is the ratio of demand to supply. For example, Apple Inc. (AAPL) may have utilization of less than 1% because the stock has vast availability relative to the demand to borrow shares for shorting. Roku Inc. (ROKU) may have utilization above 90% because of higher demand to short shares as compared to the number of available shares.

For accounts enrolled in the Stock Yield Enhancement Program, a high stock-specific Utilization percentage may increase the likelihood that we may be able to lend your shares. Conversely, stocks with a low Utilization percentage are generally in lesser demand in the securities finance market, generally reducing our ability to lend your shares.

Utilization can be added as a column in TWS.
