If you have spent any time reading about gamma exposure or max pain, almost everything you have read was probably about indices. SPY. SPX. QQQ. Maybe NDX. That makes sense, because index options are where dealer hedging is most visible and most stable. But the moment you apply the same playbook to a single ticker like AMD or NFLX, things get strange.
The gamma walls are weaker. The flip point jumps around. Max pain sometimes pins beautifully and sometimes does not pin at all. Earnings reshape the entire surface in a single afternoon. And the same level that acted as a textbook call wall on Monday can be gone by Wednesday because half the open interest closed out.
This is not because the theory is wrong. It is because single-stock options behave differently from index options at almost every layer of market microstructure. This guide walks through why that is, and then breaks down the typical gamma and max pain character of seven of the most actively traded single-stock options names on the US market: AMD, NVDA, NFLX, META, MU, TSLA, and AAPL.
Everywhere this article describes a ticker's "character," that is a pattern, not a current value. For live GEX, walls, flip, and max pain for any name, use the GEX tool or the per-ticker hub at /stock/{ticker}.
Why Single-Stock GEX Behaves Differently
Index gamma exposure is, in a sense, a smoothed-out average of thousands of underlying stocks plus an enormous, professionally hedged options book. SPY and SPX have deep open interest at every strike from far out-of-the-money puts to far out-of-the-money calls. Dealers in those markets carry large, slowly rotating books and hedge continuously. The result is the relatively clean GEX charts you see in most educational material.
Single names lose almost every one of those properties.
Property
Index (SPY, SPX)
Single name
Open interest
Dense at every strike and expiry.
Clustered at a few round numbers and a handful of expiries.
Walls
Sit where hedging is most intense; hold for days.
Sit at $100 / $150 / $200; hold only when a real OI cluster is there.
Dealer hedging
Continuous, from large slowly rotating books.
Choppy; one 5,000-lot block moves the local profile.
Weekly rhythm
Muted.
OI builds Monday to Thursday and vanishes Friday.
Event risk
Macro prints, smoothed across constituents.
Earnings, launches, M&A re-shape the whole surface overnight.
Open Interest Density
The amount of open option contracts concentrated at each strike. Indices have dense OI across many strikes and many expirations. Most single stocks have OI clustered at a few round-number strikes and a handful of expirations, which makes the resulting GEX shape lumpier and more dependent on a small number of large positions.
Idiosyncratic Risk
Single-stock risk that is not explained by the broader market. Earnings, product launches, regulatory actions, M&A, and analyst calls all move single names in ways indices smooth out. Each of these events can re-shape the option surface, GEX, and max pain almost overnight.
The practical consequences are large. Three matter most.
1. Walls are weaker and more variable
Because OI is concentrated at fewer strikes, the call wall and put wall for a single name often sit at obvious round numbers ($100, $150, $200) rather than at the precise levels where dealer hedging is most intense. When a wall is real, it can be powerful. When it is only there because retail likes round numbers, price often slides right through it.
2. Dealer hedging is choppier
For SPY and SPX, dealers carry such large books that their hedging is effectively continuous. For a mid-cap single name, the dealer book is smaller, more concentrated in a few large customer positions, and more sensitive to a single sizeable trade. A block of 5,000 calls hitting the tape on AMD or MU genuinely shifts the local gamma profile in a way the same trade on SPY would not.
3. Single-name GEX is heavily weekly-driven
Most single-name retail flow now lives in weekly options. Open interest builds Monday and Tuesday, peaks Wednesday and Thursday, and largely vanishes by Friday close. That means single-stock GEX has a strong day-of-week rhythm that index GEX does not. Monday morning gamma on AMD looks almost nothing like Thursday afternoon gamma on the same ticker.
Index GEX (SPY, SPX, QQQ)
Deep open interest at hundreds of strikes
Large, professional dealer books
Continuous, smooth hedging
Gamma flip evolves slowly
Walls are usually robust support and resistance
0DTE and weekly flows blend into a deep book
Single-Stock GEX (AMD, NFLX, MU...)
OI clustered at round-number strikes
Smaller, less-diversified dealer books
Choppy, position-driven hedging
Gamma flip can jump with a single block trade
Walls can disappear inside a single session
Weekly options dominate intra-week dynamics
None of this means single-stock GEX is useless. It means you have to read it differently than you read SPY. Treat single-name walls as zones of likely friction, not as exact price targets, and always check whether the wall is supported by real OI or is just the nearest round number.
Max Pain in Single Names vs Indices
Max pain is the strike price at which the largest total dollar value of options expires worthless. For a deeper treatment of the math, see our complete max pain guide. The short version: if you sum up the dollar value of all calls plus all puts at every strike, the strike where that combined open-interest value is smallest is max pain. The folklore is that price gravitates toward this strike into expiration.
Here is the honest version: indices like SPY and SPX pin more reliably than single names on average, because indices lack the idiosyncratic shocks that single names face every quarter. Earnings, analyst calls, FDA decisions, and product launches routinely blow up single-name pins. But in quiet OPEX weeks with no catalysts, single-name pins can be tighter than index pins because the OI is more concentrated.
Max Pain
The expiration strike at which the total dollar value of all expiring calls and puts is minimized. In practice it represents the price level least favorable to option buyers in aggregate, and the level dealers benefit most from price drifting toward.
The single-name pin pattern, when it works, works for three reasons.
First, single-name OI is more concentrated at fewer strikes. That means the max pain calculation is dominated by a few large positions, and dealer hedging incentives are pointed at a smaller set of round numbers. When most of the open interest at a name sits at $150 and $160, "between $150 and $160" is a much narrower attractor than the diffuse pin zone you would see on SPY.
Second, dealer hedging is meaningful relative to a single stock's daily flow in a way it usually is not for SPX. Large blocks of single-name delta hedging into expiration leave clear footprints on the tape, while the equivalent in an index gets absorbed by the broader flow.
Third, with weeklies dominating, much of the OI that drives single-name max pain is genuinely going to zero on Friday. By Thursday afternoon, the gamma at the max pain strike is enormous relative to the rest of the chain, and dealer hedging gets very directional toward that strike.
Critically, single-name pins are conditional. They work in quiet OPEX weeks. They fail reliably on earnings weeks, Fed weeks, and major catalyst weeks. Always check the catalyst calendar before sizing any trade around a single-name max pain pin. The index pin is more forgiving because the underlying does not have a four-times-a-year binary event.
The sections below describe the typical character of GEX and max pain behavior for each ticker. None of the descriptions reference a current price, current GEX value, or current max pain strike. For live data, follow the per-ticker link at the end of each section.
Index-like in quiet weeks. A separate regime in earnings season.
What drives it
One of the widest ranges of earnings reactions in the index: October 2022 collapsed in a session, January 2024 ripped in one.
A single sentence on ad-revenue trajectory or AI capex can move the stock 15 to 20 percent. Options price that asymmetry, and dealer books reflect it.
What it means for levels
Between prints, the surface reads close to an index: deep OI distribution, stable walls.
The quiet-week vs earnings-week contrast is more extreme than for AAPL or MSFT.
When it breaks: the next print blows the surface apart; it rebuilds slowly over the following weeks. Treating META as a low-vol megacap in the wrong week is how traders get burned.
Deep cyclical. Noisy GEX, elevated IV, and the best case study for single-stock max pain.
What drives it
The memory-chip cycle produces earnings outcomes several standard deviations apart, quarter to quarter.
IV stays elevated; OI concentrates at large round-number strikes more than most names its size.
What it means for levels
GEX is structurally noisier than AMD or NVDA: walls move more, the flip is less stable.
The max pain pin into monthly OPEX is more reliable in non-earnings months than during the print.
Why it is the case study: the contrast between earnings-week and quiet-week behaviour is as stark as it gets.
Where to Find MU Max Pain by Expiration
For the current Micron reading, open MU max pain by expiration. Read the calendar row for the expiration you intend to study and compare its max-pain strike with spot and the open-interest distribution. The MU overview provides broader ticker context; the dedicated max-pain page is the relevant view for this calculation.
Max pain minimizes aggregate intrinsic option payout weighted by open interest at a hypothetical settlement price. It is not a forecast that MU will close at that strike. Record the expiry and observation time, and check whether earnings fall before expiration before comparing it with another session.
TSLA
Retail-driven, negative-gamma megacap. Levels break more than they hold.
What drives it
Retail buys short-dated upside calls, constantly.
Dealers write those calls, so they are short gamma on the call side.
That inventory dominates the chain, so net dealer gamma stays negative. Not because dealers are short both sides; the call-side imbalance is simply that heavy.
What it means for levels
Moves are amplified in both directions.
Walls exist but break more often than they hold.
Max pain pins less reliably than on lower-vol megacaps, even outside earnings.
Lowest-vol megacap. The closest single-name analog to an index chart.
What drives it
A multi-year buyback program that consistently supports the underlying.
Deep institutional ownership and very large, professionally managed dealer books.
What it means for levels
Walls hold for weeks rather than days, anchored on obvious price-psychology levels.
The gamma flip rarely moves more than a few dollars.
Realized volatility undershoots implied for long stretches; max pain pins are tight.
When it breaks: the September product cycle (iPhone launch and the pre-print drift) and quarterly earnings. IV expands and the surface gets more sensitive to short-dated flow.
Start here if you are learning to read single-stock GEX without the chaos of TSLA.
Across all of these names, the single most useful question is: "Is this name in or near an earnings cycle?" In single-stock GEX, earnings dominates almost every other consideration. Pin levels, walls, and the flip are all far more meaningful in quiet weeks than in event weeks.
OPEX Week Dynamics for Single Names
Index OPEX matters because of the sheer scale of expiring gamma. Single-stock OPEX matters for a different reason: because a much larger fraction of a single name's total open interest is concentrated in the monthly cycle. For many tickers, the third Friday of the month carries half or more of the name's open option contracts.
That concentration creates several effects worth knowing.
First, the call wall and put wall on a single-name monthly chain are usually the most meaningful levels of the entire month. Even if the same strikes look weaker on the next weekly, the monthly version of those walls genuinely matters because the OI is dramatically larger.
Second, the max pain pin into single-name OPEX is generally tighter than into single-name weeklies. The pin works best when there is no earnings event in the same week and no major macro print on the calendar.
Third, the post-OPEX Monday is often the most important single trading day of the month for single names. With the bulk of the monthly OI gone, the gamma stabilizers vanish almost overnight. Names that were range-bound for two weeks can suddenly trend, and names that were pinned at a round number can gap to find new equilibrium.
Be especially careful with single-name OPEX trades when earnings sit inside the same week. The combination of an event move plus the gamma unpin on Friday's close can produce two-sided risk that is materially larger than either factor would produce alone.
The honest answer is that single-stock GEX is most useful as a context layer, not as a stand-alone signal. Used well, it tells you what kind of week you are likely about to trade in a particular name. Used poorly, it gives you false confidence in exact price targets that the market never agreed to respect.
A reasonable workflow looks something like this.
Check the gamma regime for the name
Is net GEX positive or negative? Where is the gamma flip relative to spot? In positive gamma, expect more range-bound behavior. In negative gamma, expect bigger trending moves.
Identify the call wall and put wall
Confirm they are backed by real OI, not just round-number bias. Treat them as zones of likely friction, not as exact reversal points.
Check max pain into the next monthly expiration
If you are inside OPEX week and there is no major event on the calendar, max pain becomes a real attractor. If there is an earnings event, set max pain aside until after the print.
Map the catalyst calendar
Earnings, analyst days, FDA decisions, product launches. Any of these can invalidate the gamma map within a single session. Always know what is coming.
Size for the actual volatility regime
Negative-gamma single names move faster than negative-gamma indices. Position sizing should reflect realized volatility, not the calmer behavior you might see on SPY.
Used this way, single-stock GEX becomes a way of asking better questions about a name rather than a way of producing trade signals on autopilot.

Frequently Asked Questions
Yes, but conditionally. Indices pin more reliably on average because they lack the binary earnings shocks single names face four times a year. However, in quiet OPEX weeks with no catalysts, single-name pins can be tighter than index pins because the OI is more concentrated. Always check the catalyst calendar first.
Single names have lower open-interest density per strike, smaller dealer books, more idiosyncratic risk, and a much heavier reliance on weekly options. The result is choppier hedging, weaker and more variable walls, and a gamma flip that can jump on a single large trade. The same theoretical framework still applies, but levels move faster and are less robust.
AAPL and META, in that order. Both are mega-caps with deep, well-distributed open interest and large professional dealer books, so their GEX surfaces behave closer to indices than other single names. TSLA and NFLX are interesting but more volatile and event-driven, so they are easier to misread when you are still learning.
Yes. The FlashAlpha GEX tool and API cover 6,000+ US stocks and ETFs. For each ticker you get net GEX, per-strike gamma, the call and put walls, the gamma flip, and max pain across all listed expirations. See the GEX tool, the API documentation, or the per-ticker pages at /stock/{ticker}.
TSLA has unusually heavy retail demand for short-dated upside calls. Dealers writing those calls become persistently short calls (negative gamma from the dealer's view), and the call-side imbalance dominates the rest of the chain. Net dealer gamma stays negative, which means dealer hedging amplifies moves rather than dampens them.

Conclusion
Single-stock GEX and max pain are real, useful tools. They are just not the same tools you use on SPY. Open interest is sparser, dealer books are smaller, weekly options dominate the intra-week rhythm, and earnings can rewrite the entire surface in a single afternoon. Walls are zones rather than exact lines, the flip can jump, and the max pain pin works best in quiet weeks with no events on the calendar.
Every name in this guide has its own character. AAPL behaves like a clean index. META is close, with event sensitivity. AMD, NVDA, and MU are cyclically driven with strong earnings overlays. NFLX is dominated by quarterly prints. TSLA carries a persistent negative-gamma lean because of its retail-heavy options book. None of these are guesses about today's chart. They are durable structural patterns that show up across multiple cycles.
The right habit is simple. Before you trade a name, ask three questions. What does the GEX regime look like right now. Where are the walls and is OI behind them. Is there an event inside the window I care about. If you have honest answers to those three questions, the rest of the analysis writes itself. Live levels for any US ticker are a click away on the per-stock pages or the GEX tool.
