ASML-Q4-2025 Earnings Trade

Trade Idea: Selling ASML $850 Put (Exp 10/17) Strike: $850 Put Expiration: Oct 17, 2025 (3 days away) Premium Collected: ~$2.80 (midpoint between $2.60 bid / $3.00 ask) Implied Volatility (IV): 110.4% Open Interest: 1,406 Volume: 744 Chance of Profit: ~92.7% Delta: –0.064 (≈ 6% chance of finishing ITM)

1️⃣ High IV = High Premium Opportunity

With implied volatility over 110%, the market is pricing in extreme movement around ASML’s upcoming earnings.
That means option prices are inflated — a prime setup for option sellers.

By selling the $850 put, I’m essentially taking the opposite side of the panic: betting that ASML won’t collapse post-earnings. Even a small upside or neutral reaction will cause volatility to implode, crushing option premiums (which benefits sellers).

2️⃣ Bullish-to-Neutral Outlook

Selling a put at $850 implies:

You’re comfortable owning ASML at an effective price of $847.20 ($850 – $2.80 premium).

You’re bullish or neutral — expecting the stock to stay above $850 through expiration.

Given ASML’s current price near ~$870–$880, the strike is ~3–4% OTM — a reasonable cushion if earnings are not disastrous.

3️⃣ Theta & Volatility Decay as Tailwinds

Theta (–2.10): Works in your favor — you gain ~$2.10/day in time decay per contract as expiration nears.

Vega (+0.109): Post-earnings IV crush will reduce option value sharply.

Combined, this means time + volatility both decay in your favor after the event.

⚖️ Risk / Reward Scenarios
🟢 Best Case Scenario

ASML trades flat or higher post-earnings.

The put expires worthless; you keep the full premium ($280/contract).

You profit purely from volatility collapse and time decay.

→ ROI: 100% of collected premium
→ Max Gain: $280 per contract

🔴 Worst Case Scenario

ASML drops below $850 by expiration.

You may get assigned and need to buy 100 shares at $850.

Effective cost basis: $847.20 (after subtracting premium).

If the stock falls sharply (e.g., to $830), your paper loss = $1,720 per contract.

This trade only loses significantly if ASML tanks >3–4% overnight, which is below implied move expectations.
