Frequently asked questions
- What is the SMCI put/call ratio?
- Puts traded divided by calls traded for Super Micro Computer (SMCI) options in the current session (the volume ratio), and total put open interest divided by call open interest (the open-interest ratio). Above 1 means more puts than calls; most single stocks sit between 0.5 and 1, index ETFs like SPY run higher because they are used for hedging.
- Which ratio should I read, volume or open interest?
- Volume is today's flow and moves fast; open interest is the standing book and moves slowly. A volume ratio far above the open-interest ratio means today's trading is more put-heavy than the positions already open, which is the kind of divergence worth noticing.
- Is a high put/call ratio bullish or bearish?
- Both readings exist. Taken at face value it is bearish positioning; as a contrarian gauge, extreme put buying has often marked short-term lows. The ratio is one input, not a signal, so pair it with the dealer levels and the expected move for the same ticker.
- How fresh is this number?
- Only contracts whose last trade printed in the most recent trading session count toward volume; stale rows are excluded so the ratio never mixes weeks-old prints with today's. The page refreshes every 15 minutes.
