TSM Earnings Report

Analysis based on market close March 31, 2026

Earnings Verdict

Earnings in 17 days (4/16). IV is elevated for the 4/17 expiration (50.6%), making IV crush plays attractive. The regime has shifted dramatically from negative to positive GEX (+$4.2M) and strongly bullish flow (+$32.3M net premium), suggesting dealer support and potential for a controlled move. The key risk is a breakdown below $300 given persistent OTM put buying, but the pinning gamma and bullish flow favor a contained reaction.

Confidence:
7 / 10
base 5; +1 elevated IV (45.6%) for earnings week; +0.5 strong historical beat rate; +0.5 bullish flow regime; +0.5 pinning gamma; -0.5 large OTM put flow
Most important: Regime shift from trending (negative GEX) to pinning (positive GEX) with massive bullish flow. This changes the risk profile from 'high probability of large move' to 'higher probability of contained move'.
🔄DRAMATIC REGIME SHIFT: GEX flipped from -$46M (trending) to +$4.2M (pinning). Flow flipped from -$25M to +$32M (bullish). This fundamentally changes the volatility profile.
⚖️Spot ($331.25) is now only 1.9% below max pain ($337.5) vs 6.5% previously. The gravitational pull upward is stronger.
🎯Earnings date confirmed for 4/16 via EPS estimate. IV term structure peak at 4/17 expiration (50.6%).

Capitalizes on elevated IV with defined risk. The pinning gamma regime (+GEX) supports a contained move. Strikes calibrated to expected move using available strikes.
Outperforms: Stock stays within the 8.8% expected move bounds ($302.5-$360). Benefits from IV crush, theta, and pinning gamma.
Underperforms: Stock gaps beyond either short strike, especially below $300 where put flow is heavy.

BE: $336.50
Trigger: Enter on any pullback toward $325-$328.
Aligns with massive bullish net premium flow (+$32.3M) and call OI walls at $330/$340. Spot below max pain ($337.5) provides gravitational pull upward.
Outperforms: Stock rallies to or above $340 by expiration. Benefits from delta and IV crush if move is gradual.
Underperforms: Stock stays flat or declines below $330.
Long Straddle (Volatility Expansion)
Buy $330 straddle exp 4/17
Max loss: $29.20
Max gain: Unlimited

Outperforms: Actual move exceeds the 8.8% expected move by >30%.
Underperforms: Stock pins near $330 and IV crushes heavily post-earnings.
Put Ratio Backspread (Bearish Tail Hedge)

Max loss: $8.50
Max gain: Unlimited below $280
BE: $298.50

Cheap hedge against the tail-risk signaled by deep OTM put flow. Credits received offset cost. Aligns with the bearish undercurrent despite bullish near-term flow.
Outperforms: Stock declines sharply below $290. Profits from delta and vega expansion on crash.
Underperforms: Stock rallies or stays flat above $300.

Risk Assessment

!Gap Risk: The 8.8% expected move is large. A break below $300 could accelerate due to heavy put OI, but pinning gamma (+GEX) should dampen moves.
!IV Crush: Estimated 15-18 vol point drop. Primary profit driver for credit spreads; major risk for long straddles.
!Liquidity: Excellent, with high open interest at key strikes ($330, $340, $300).
!Sizing: Given regime shift to pinning, standard position sizes are appropriate. The long straddle remains high-risk due to crush.

What to Watch

?Spot price action relative to $330 (gamma flip) and $337.5 (max pain). A hold above $330 strengthens the pinning thesis.
?IV trajectory into earnings for the 4/17 expiration. A spike above 55% improves entries for short vol strategies.
?Flow in the $340C and $300P strikes for confirmation of bullish/bearish conviction.
