Options Focus | TSMC Earnings Loom, IV Prices in ~5% Move; $1M Block Targets $370 Calls and Institutions Sell Longer-Dated $300 Puts for Premium

$Taiwan Semiconductor Manufacturing Co. (TSM)$ 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.
