TAIEX Options 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/hedging positioning that has grown crowded — reflecting a bullish market lean. PCR below 100% means calls dominate and hedging is thin, indicating a more bearish market lean. Open-interest PCR tracks medium-to-long-term sentiment shifts; volume PCR captures short-term activity.
