Taiwan Semiconductor Manufacturing Co. is set to report its latest quarterly results before the market opens on April 16, 2026. Ahead of the release, options activity has intensified, with institutional positioning reflecting a complex mix of short-term bullish bets and longer-term downside hedging.

Market expectations and options pricing

Investors are bracing for strong growth in the current quarter. Consensus estimates call for revenue of $35.16 billion (up 38.87% year-on-year) and earnings per share of $3.28 (up 61.29%). Key focus areas include demand for AI-driven advanced nodes, margin trajectory, and progress on global capacity expansion.

Options markets have largely priced in the event risk. Implied volatility currently stands at 61.81%, with options implying a ±5.60% move for the week of earnings. Based on the current share price of $369.57, this suggests a one-standard-deviation range of $348.87 to $390.27 post-earnings.

Open interest positioning

For April 17 expiries—the first trading session after earnings—open interest is concentrated at key strikes:

• Puts: Heavy positioning at $330 (OI: 16,793) and $340 (OI: 16,673)

• Calls: Clusters at $340, $350, and $370, with the $350 strike holding the largest OI at 9,740

These levels may act as near-term support and resistance following the earnings release.

Block trades reveal institutional strategies

Recent large trades underscore diverging views and sophisticated positioning:

1. Short-term mildly bearish stance via call spread

• Trade: Bought 5,400 Apr 17 $350 calls (~$12.34 million) and sold 2,700 Apr 17 $335 calls (~$9.81 million)

$TSM Vertical 260417 335.0C/350.0C$

Interpretation:

This resembles a bearish call spread structure, suggesting expectations that the stock may decline or struggle to sustain gains post-earnings.

2. Long-term bullish premium harvesting

• Trade: Sold 3,727 Dec 18, 2026 $300 puts (~$7.45 million)

$TSM 20261218 300.0 PUT$

Interpretation:

This reflects long-term confidence in the stock, with sellers willing to accumulate shares at $300 while monetizing elevated volatility through premium collection.

3. Aggressive short-term upside bet

• Trade: Bought 1,719 Apr 17 $370 calls (~$1.46 million)

$TSM 20260417 370.0 CALL$

Interpretation:

A high-leverage directional bet that the stock could break above $370 sharply following earnings.

Takeaways and strategy considerations

TSMC’s options market exhibits a classic “intense short-term positioning alongside longer-term strategic allocation” ahead of earnings:

• Short-term: Active trading around earnings outcomes, with both bullish and bearish structures

• Long-term: Institutions selling puts to generate income and position for potential accumulation

• Key upside level: $370 (target of aggressive call buying)

• Support zones: $360 and $330 (areas with heavy put open interest)

Strategy view:

With implied volatility elevated, option-selling strategies may be attractive. The lower bound of the implied move—around $348—could serve as a reference zone for put selling, though the heavy $330 put open interest suggests a potential stress-test level.

For investors seeking defined risk, structures such as bull call spreads (e.g., long $350 call / short $370 call) offer a more balanced approach, capping both risk and reward while aligning with the market’s implied range.

Close attention should be paid to whether shares can sustain a break above $370 post-earnings, or find support near $360 and $330 during any pullback.
