Taiwan Semiconductor Manufacturing Company closed at USD 422.06, up 0.86%.
Taiwan Semiconductor (TSM) saw a decisive bullish skew in its options activity, with total bullish premium of $0.69 million dwarfing a modest $0.09 million in bearish flow. The standout trade was a bullish synthetic long, while the only large bearish print was a net-credit double put sale, suggesting premium collection rather than a strong directional bet.

Options Indicators
TSM’s implied volatility is 39.51%, while its IV percentile stands at 14.34%, which places current option pricing in the lower end of its historical range. In other words, volatility is relatively subdued and options appear cheaply priced rather than expensive. At the same time, the IV/HV ratio of 0.90 suggests implied volatility is running slightly below realized volatility, reinforcing the view that current premiums are not stretched and that option pricing is comparatively modest. The Call/Put volume ratio is 0.75.
Large Trades
A net-credit same-direction double PUT sale worth $0.09 million was the displayed large trade, with traders selling two blocks of the 2026-08-21 $350.00 puts for a combined net credit of $0.09 million. Both legs were out of the money versus the $422.06 reference stock price, making this a premium-collection structure that benefits most if TSM stays above the strike and volatility remains contained. Strategically, it reflects a range-bound to mildly bearish stance rather than an outright aggressive downside bet, as the seller is monetizing time decay while taking on downside assignment risk if the stock weakens materially toward $350.00. Overall sentiment across all large trades was bullish, with total bullish flow of $0.69 million against bearish flow of $0.09 million, leaving a net difference of $0.60 million to the bullish side. The directional read is clearly positive because the largest capital commitment came from a bullish synthetic long position, while the only notable bearish flow was a modest net-credit PUT-selling structure that looks more like premium harvesting with downside risk than a high-conviction bearish attack. Taken together, the large-trade tape suggests institutional positioning leaned bullish on TSM, with traders willing to express upside exposure more aggressively than downside protection.
Strategy Reference
For traders seeking to mirror the premium-collection structure with a low assignment probability, selling the out-of-the-money $350.00 put in a nearer expiration or deploying a put credit spread by buying a lower strike put can help cap downside risk while maintaining a net-credit profile.
