What is the ISE Sentiment Index (ISEE)?
ISEE is an indicator of bullish/bearish investor sentiment that is computed using a unique calculation methodology and proprietary ISE option trade data. Unlike traditional put/call ratios, ISEE is based on opening long customer transactions only. Trades by market makers and firms are excluded as these tend to skew sentiment value. As a result, ISEE provides a more accurate reflection of true investor sentiment. For more details on our calculation methodology, please click on the “Details” tab.
