Options Indicators

TSM’s implied volatility is 57.55%, and with an IV percentile of 94.82%, current option pricing sits in an elevated range, indicating that volatility is high relative to its own recent history and that options are expensively priced.

The IV/HV ratio of 1.10 also suggests implied volatility is running modestly above historical realized volatility, reinforcing the view that the market is attaching a premium to near-term uncertainty.

The Call/Put volume ratio is 0.60.

Large Trades

A PUT sale worth $4.63 million was the largest displayed trade, with 1,500 contracts of the September 18, 2026 $400.00 put sold while the stock reference price was $402.30.

This was an out-of-the-money single-leg put sale, indicating a moderately bullish stance, as the seller is expressing willingness to own TSM near the $400.00 level while collecting premium upfront.

Strategically, this type of trade is typically associated with premium collection and constructive positioning, reflecting confidence that the shares will remain above the strike or that any pullback toward that level would be manageable.

A PUT buy worth $0.55 million involved 3,300 contracts of the August 21, 2026 $300.00 put, also established out of the money versus the $402.30 stock reference.

As a single-leg long put position, this trade is clearly bearish in direction, targeting downside protection or a speculative move lower into expiration.

Because the strike sits well below the current share price, the trade suggests the buyer is positioning for tail-risk protection or a significant bearish move rather than a mild decline.

Overall, the large-trade flow in TSM was bullish, with $5.65 million in bullish premium versus $0.55 million in bearish premium, leaving a net bullish difference of $5.10 million.

The directional judgment is clearly constructive, as the dominant activity was concentrated in sizeable out-of-the-money put selling, which typically reflects premium-collection interest and confidence in downside support.

While there was some bearish hedging or speculative put buying, its scale was far smaller, so the broader message from large traders was that sentiment remained meaningfully positive rather than defensive.

Strategy Reference

For premium sellers aiming for a low probability of assignment, selecting a put strike 5-10% below the current share price, such as the $380.00 or $370.00 level, could be considered; alternatively, traders preferring defined risk and lower margin requirements might implement a bull put spread by buying a further out-of-the-money put to cap the maximum loss.
