Taiwan Semiconductor Manufacturing closed at USD 415.58, down 1.34%.
Options on TSM lit up with a compelling clash of sentiment, as a dominant $1.78 million put sale defending the $400.00 floor faced off against a matching $1.70 million put purchase targeting the same strike. This simultaneous flow, both set for the July 2026 expiration, exposes a tug-of-war between premium sellers confident in a long-term floor and bears loading up on deep downside protection.

Options Indicators
TSM’s implied volatility is 53.46%, and with an IV percentile of 84.86%, current volatility is sitting in an elevated zone relative to its own recent history, indicating that options are priced expensively rather than cheaply. At the same time, the IV/HV ratio of 1.04 suggests implied volatility is only slightly above realized volatility, so while premium levels are rich on a historical percentile basis, the market’s forward pricing is not dramatically disconnected from the stock’s actual recent movement.
The Call/Put volume ratio is 0.81.
Large Trades
A PUT sale worth $1.78 million stood out as the largest displayed trade, with 2,500 contracts of the July 31, 2026 $400.00 put sold. With TSM referenced at $415.58, this strike was out of the money at the time of the trade, making it a moderately bullish income-style position. By selling the put, the trader collected premium while expressing the view that shares would likely remain above $400.00 through expiration, or at least that downside risk would stay limited enough for the premium received to be attractive.
A PUT purchase worth $1.70 million followed closely behind, consisting of 2,500 contracts of the July 31, 2026 $400.00 put bought. This was also an out-of-the-money position versus the $415.58 reference stock price, but unlike the sale above, this trade was clearly bearish in intent. Buying this put gives the trader downside exposure below the $400.00 strike into expiration, suggesting either a directional bet on weakness in TSM or a protective hedge against a decline over the same time horizon.
Overall sentiment across all large trades leaned modestly bullish, with total bullish flow of $1.98 million versus $1.70 million in bearish flow, for a net difference of $0.28 million to the bullish side. The directional judgment is therefore mildly bullish rather than decisively so, because the bullish edge came from premium-selling activity in out-of-the-money puts, while the bearish side was concentrated in a sizable put purchase at the same strike and expiration. Taken together, the flow suggests the market is still willing to sell downside premium and defend the $400.00 area, but there remains meaningful demand for downside protection or speculative bearish exposure.
Strategy Reference
For a defined-risk approach that avoids the large margin requirement of a naked short put, consider a put credit spread by selling the July 2026 $400.00 put and buying a further out-of-the-money put, such as the $350.00 strike, to cap risk while still capturing the elevated premium from the rich IV percentile.
