From Intraday TSLA Volatility to a 10:1 Payoff
Case Study Snapshot: NFLX | Jan 21, 2025
Heading into NFLX earnings, the options market priced in a 7.4% move — an expected range of $800 to $925. However, Equity Hub’s Total Open Interest model showed something different.
The Setup
The Total OI model revealed that NFLX could extend well beyond the implied move, with no major resistance until $1,000 — pointing to a larger expansion than the market had priced in. NFLX surged nearly 15% post-earnings, reaching an intraday high of $999 before closing at $954.
Outcome & Why It Matters
Traders relying only on the implied range saw the move stretch beyond expectations. Using SpotGamma’s insights, traders could apply their edge in NFLX — and structure better trades with full awareness of the most likely scenarios.
