ISEE is available through the Bloomberg terminal on the function ISEE . Here Bloomberg's more than 200,000 users are able to access information about the index, the calculation methodology, and the level of the Sentiment Index. Through Bloomberg's functionality, users of Bloomberg terminals can for the first time view the ISEE in a variety of formats, including charts and time periods.
The ISEE is designed to measure the level of investor trading volume in calls versus puts. The ISEE is often used by investors to gauge investor sentiment toward the stock market. The ISEE measures only opening long customer transactions on ISE. Transactions made by market makers and firms are not included in ISEE because they are not considered representative of market sentiment due to the often specialized nature of those transactions. Customer transactions, meanwhile, are often thought to best represent market sentiment because customers, which include individual investors, often buy call and put options to express their sentiment toward a particular stock.
