TAIEX Options Put/Call Ratio

What is Options PCR (Put/Call Ratio)?

The Options PCR (Put/Call Ratio) measures the ratio of put to call open interest in Taiwan's TAIFEX index options market. PCR above 100% signals heavier put positioning — reflecting bearish sentiment or increased hedging. PCR below 100% means calls dominate, indicating a more bullish market lean. Open-interest PCR tracks medium-to-long-term sentiment shifts; volume PCR captures short-term activity. Blave provides historical TAIFEX options PCR charts and daily put/call breakdowns.
