Options Indicators

TSM’s implied volatility is 36.08%, and with an IV percentile of just 1.99%, current option volatility sits at the low end of its historical range, indicating that options are cheaply priced rather than expensive. At the same time, the IV/HV ratio of 1.55 shows implied volatility is still running above realized volatility, meaning the market is pricing in more future movement than the stock has recently delivered, but overall the option premium environment remains relatively inexpensive by historical standards.

The Call/Put volume ratio is 1.79.

Large Trades

A call purchase worth $57.52 million was the dominant large trade in TSM, consisting of a single-leg buy of 9,700 contracts in the 380.0 strike call expiring on 2026-11-20. With the stock reference price at 427.3, this call was already in the money at execution, which makes the trade a clearly bullish position with meaningful intrinsic exposure in addition to time value. The use of a long-dated in-the-money call suggests the buyer was positioning for sustained upside while controlling capital outlay versus outright stock ownership, indicating confidence in TSM’s medium- to long-term price strength.

Overall, the large-trade flow was decisively bullish. The displayed block was a straightforward upside call buy rather than a hedged or premium-selling structure, and the broader bulk-order activity also leaned entirely to the bullish side, reinforcing the view that institutional positioning was oriented toward further appreciation in TSM. Taken together, the figures point to constructive market sentiment, with traders expressing directional conviction through outright call buying rather than defensive or neutral strategies.

Strategy Reference

For a low assignment probability income approach, a seller could consider shorting a 0.10–0.15 delta out-of-the-money put or call in a shorter-dated expiry, while bullish traders who prefer not to post the full margin of a long call could use a call debit spread, such as buying the 430 call and selling the 460 call, to cap risk and define maximum loss.
