What Works When the Market Is Greedy? Options, Futures and Stocks by Fear & Greed Zone
The stock market’s Fear & Greed index sums up the mood in one number, from 0 (extreme fear) to 100 (extreme greed). A 0-DTE butterfly rule we had tested made its money on fear days and lost on greed days. So we asked the opposite question: what works when the index reads greed? We split years of replayed trades in SPY options, index futures and 30 stocks by the reading known before each session.

The short answer
The short answer
On days the stock market’s Fear & Greed index read greed (55 or over), selling options and staying long worked; buying options and shorting did not. A short strangle on SPY expiring about 3 trading days out made +$111 per trade per contract on greed days (83% winners) against +$18 on fear days, and selling a call alone made +$45 against −$37, while buying calls or puts lost $42 and $110. In index futures only the long side held up in greed, and for stocks extreme greed was not a sell signal. The reason in the data: greed days moved less than the options market priced, and it already priced less (a next-day move of 0.70%, against 1.00% on fear days). The options test covers one mostly rising market (2024–2026, 256 greed days) with overlapping trades and a worst strangle loss of about $1,100 per contract.
- per SPY short strangle on greed days (+$18 on fear days)
- +$111
- next-day move options priced on greed days (1.00% in fear)
- 0.70%
- a session, NQ futures, long side only, on greed days
- +$141
- luck tests that beat the greed results for selling options
- 2–6 of ~620
Key takeaways
- Selling SPY options about 3 trading days out paid on greed days: short strangle +$111 per trade per contract (83% winners) vs +$18 on fear days, short straddle +$151 vs +$36, iron condor +$59 vs +$5.
- Selling a call alone is the clearest greed-only result: +$45 per trade on greed days (87% winners), −$37 on fear days.
- Buying options lost on greed days: −$42 per bought call and −$110 per bought put.
- Index futures: only the long side held in greed. The night-day rule, long only, was positive in 7 of 8 test sets (NQ +$141 a session); momentum and night-day shorts lost.
- Stocks: extreme greed was not a sell signal. The 200-day trend rule made $9.89 a day per $10,000 on greed days and buy and hold $8.27; on extreme-greed days $16.73 and $12.11.
- Greed days are calm: options priced a 0.70% next-day move (1.00% in fear), and prices moved even less than that.
- As a filter on other strategies the index did not help: in the year after a midterm, Fear & Greed rules picked blind made +21.2% a typical year against +30.4% for the plain rule.
01
What we tested
Four groups of strategies, each split by the Fear & Greed reading known before the session. Greed means 55 and over; fear means 45 and under. The same trades on both kinds of days show whether the mood changes the result.
1Options on SPY
Tested: 16 plain structures — among them short strangles, short straddles, iron condors, covered calls, and buying or selling single calls and puts — opened at 10:30 and held to expiry, on 678 days from January 2024 to October 2026 (256 greed days). Three expiries: the same day (0-DTE), the next expiry, and the furthest stored, about 3 trading days out.
Found: Selling calls, or both sides, about 3 days out earned far more on greed days than on fear days. Buying options lost.
2Index futures
Tested: 8 day-trading and overnight rules from our futures tools, each run both ways, long only and short only, risking $900 a trade — on QQQ and SPY 1-minute bars 2016–2026 and on real NQ, ES, YM and RTY futures 2024–2026.
Found: On greed days only the long side held up. The momentum and night-day shorts lost clearly, and most day-trading rules were negative.
3Stocks
Tested: An equal-weight basket of 30 well-known stocks and ETFs, October 2016 to October 2026: buy and hold, the 200-day trend, dip buying, and short-term signals (Bollinger Bands, mean reversion, momentum).
Found: The 200-day trend edged out buy and hold on greed days, extreme greed was not a reason to sell, and short-term signals earned almost nothing.
40-DTE broken-wing butterflies
Tested: All 432 replays of our 0-DTE butterfly study (6 rules, 2 wing widths, 12 entry times; both sides, puts only or calls only) on the same 678 days, after fees, split by zone (258 greed days).
Found: With wings set by the market, every rule lost on greed days at all 12 entry times. One wide-wing rule made money in greed, but no more than luck, and not after the bid-ask spread.
02
Options on SPY: greed against fear
Dollars per trade per SPY contract, opened at 10:30 and held to expiry about 3 trading days out, at mid prices. An expected move is what the options market prices for the move — here the price of the at-the-money straddle. A short strangle sells a call above and a put below the price; a short straddle sells both at the price; an iron condor is a short strangle with cheaper options bought further out to cap the loss.
| Structure | Greed days | Fear days | Won on greed days |
|---|---|---|---|
| Short strangle, call and put 1 expected move away | +$111 | +$18 | 83% |
| Short straddle, call and put at the price | +$151 | +$36 | — |
| Iron condor, sold 1 move away, bought 2 moves away | +$59 | +$5 | — |
| Sell a call 1 expected move above | +$45 | −$37 | 87% |
| Covered call: shares plus a call sold 0.5 move above | +$148 | +$127 | — |
| Plain shares, held the same days | +$92 | +$180 | — |
| Buy a call | −$42 | — | — |
| Buy a put | −$110 | — | — |
— = not reported. Selling puts made money in both zones, so it is not a greed effect. The covered call beat shares on greed days and lost to them on fear days, but both gaps sit inside the luck range. The same signs showed at 0 and 1 day to expiry, only weaker: the 1-day strangle made +$43 a trade, and just +$9 in the first half of the period.
03
Why greed days are different
An option seller is paid for the move the market expects and loses only when the real move is bigger. On greed days the options market already priced less: for the next day, an expected move of 0.70% of SPY’s price, against 1.00% on fear days. And prices then moved even less than that. Small moves on cheap-looking options are the best case for a seller and the worst for a buyer — which is why selling paid and buying lost.
The calm shows in plain prices too. From 2016 to 2026 SPY’s typical daily swing was 0.75% on greed days against 1.0–2.1% on fear days. From 2022 to 2026 the standard deviation of SPY’s moves in a day was 0.63% on greed days against 1.61% on extreme-fear days.
What did not change is direction. SPY’s overnight moves (close to next open) and daytime moves (open to close) were no different by zone in 2022–2026. Greed days are not up days or down days; they are quiet days. That is why the index helped choose what to sell but did not call the market.
04
Index futures: only the long side held
Our futures rules on greed days, risking $900 a trade, in dollars per session. The t-score shows how far a result sits from zero compared with its own noise: the further from zero, the less likely it is chance. NQ, ES, YM and RTY are the Nasdaq-100, S&P 500, Dow and Russell 2000 futures.
| Rule and direction | On greed days |
|---|---|
| Night-day (an overnight hold plus day-session trades), long only | Positive in 7 of 8 test sets; NQ +$141 a session (t 2.7 on futures) |
| The overnight leg alone, long | Positive on all 4 futures, +$37 to +$88 (t 2.9 pooled) — but the same on fear days |
| Momentum, long only | Positive in 6 of 8 test sets, small |
| Momentum, short | Lost (t −4.3 on futures) |
| Night-day, short | Lost (t −3.4) |
| Opening-range breakout, VWAP pullback, VWAP fade, candle range | Negative |
| The 10 am rule | Negative — positive in 0 of 8 test sets |
| Gap fill | About zero |
The overnight edge is not a greed effect: it earned as much on fear days. What greed changed is the short side, which lost clearly, and the day-trading rules, which mostly lost.
05
Stocks: the 200-day trend and buy and hold
An equal-weight basket of 30 well-known stocks and ETFs, October 2016 to October 2026, in dollars a day per $10,000. The 200-day trend rule holds a stock only while it is above its 200-day average; dip buying buys after a drop. The 30 names were chosen with hindsight, which flatters every row.
| Way to hold | Greed days (55+) | Extreme-greed days (75+) | Fear days (45 and under) |
|---|---|---|---|
| 200-day trend | +$9.89 | +$16.73 | — |
| Buy and hold | +$8.27 | +$12.11 | — |
| Dip buying | +$4.18 | — | +$7.34 |
| Bollinger Bands | about +$0.2 | — | +$2.51 |
| Mean reversion, momentum | about +$0.2 | — | — |
— = not reported. On greed days the 200-day trend beat buy and hold in both halves of the decade (t 3.2 against 3.4 for holding). The short-term signals were in the market on only 2–6% of greed days. Growth stocks beat defensive ones by the same amount in greed and in fear.
06
Fear & Greed as a filter on other strategies
Splitting results by zone shows where a rule earns. Adding the index as a filter is a harder test: does it still help once everything else has been tried?
0-DTE butterflies by zone
The strongest rule of our 0-DTE broken-wing butterfly study (a butterfly spread with one wing wider than the other, opened at 11:30 with wings set by the market) made +$6,780 in total on 86 extreme-fear days and +$2,138 on fear days, lost $3,431 on neutral days and lost $22,990 on 242 greed-zone days — negative in both halves. A fear trade, not a greed trade.
The butterfly search
Fear & Greed level, zone and its 5- and 20-session change were added to a search of every pair of 5,610 conditions at 12 entry times, and every triple of 1,412 daily conditions (Fear & Greed and weekday included) — 2.2 billion combinations. No Fear & Greed condition made a top-10 list, and the best combination stayed the same.
The year after a midterm
On top of a 3× S&P 500 rule for the year after US midterms, 121 Fear & Greed rules were tried. 30 beat it on paper (best +41.8%), but with only 3 post-midterm years to test (since 2014), the rules picked without seeing the year made +21.2% a typical year (worst −7%) against the plain rule’s +30.4% (worst +13%).
Overnight futures
The overnight leg earned on all 4 futures on greed days (+$37 to +$88, t 2.9 pooled), and the same on fear days. The zone added nothing there.
07
Is it luck? How we checked
With many structures and only a few hundred greed days, some results will look good by chance. These checks separate the ones that held from the ones that did not.
Shifted labels
We moved the greed and fear labels onto other days, about 620 times, and re-ran everything. For the 3-day strangle, straddle, condor and sold call, only 2–6 of those shifted runs did as well as the real labels.
Shorter expiries
The same trades closer to expiry were weaker. The 1-day condor was matched by 31 of 618 shifted runs; the 1-day strangle made +$43 a trade, and only +$9 in the first half.
Inside luck
Selling puts (it earned in both zones), the covered call against shares, and the wide-wing butterfly rule in greed — positive at all 12 entry times and in both halves, yet beaten by 221 of 638 shifted runs at 10:30.
Both halves
The 200-day trend beat buy and hold on greed days in both halves of 2016–2026. The strongest butterfly rule lost on greed days in both halves. The 1-day strangle almost vanished in the first half.
Butterflies in greed
With wings set by the market, every butterfly rule lost on greed days at all 12 entry times; the strongest averaged −$19.8k on greed days against +$5.3k on fear days. Only wide wings made money in greed: one rule at all 12 times (+$4.3k on average; +$1.8k at 10:30, +$5.6k at 11:30, +$6.7k at 1:00 pm) while losing on fear days, and a puts-only version at 12 of 12 times but tiny (+$1.3k on average).
Costs
That wide-wing rule trades about 23 contracts a day. A $2-a-contract bid-ask spread turns every entry time negative (−$4.3k to −$11.0k).
08
The risks
- One mostly rising market: the options test covers January 2024 to October 2026, 678 days with 256 greed days. Greed in a falling market may behave differently.
- High win rates hide big losses: the short strangle won 83% of greed-day trades, but its worst trade lost about $1,100 per contract, against an average gain of $111.
- Overlapping positions: a new trade opens every day and lasts about 3 trading days, so several are open at once and move together. The real risk at any moment is a stack of trades, not one.
- Costs and size: on XSP (mini S&P 500 index options) the edge per contract was a tenth as big while the fee stays $0.55 a leg, so the condor turns about negative after the bid-ask spread.
- Prices: the last trade was taken as the mid price, and positions were held to expiry. Take-profit or stop exits, and expiries longer than about 3 trading days, were not tested.
- The stock basket of 30 names was chosen with hindsight, and the futures results on real contracts cover only 2024–2026.

Questions
Is the Fear and Greed index a good trading signal?
Not for direction. In 2022–2026 SPY’s overnight and daytime moves were no different by zone; greed days were simply quieter. It helped choose what to sell: on greed days a short SPY strangle about 3 trading days out made +$111 per trade per contract against +$18 on fear days. As a filter added to other strategies it did not help: in the year after a midterm, Fear & Greed rules picked blind made +21.2% a typical year against +30.4% for the plain rule.
What should you trade when the market is greedy?
In this backtest, selling options and staying long did best on greed days (Fear & Greed 55 or over). On SPY about 3 trading days out: short straddle +$151, short strangle +$111, iron condor +$59, a sold call +$45 per trade per contract. In index futures only long rules held (NQ night-day long +$141 a session). For stocks, the 200-day trend made $9.89 a day per $10,000 against $8.27 for buy and hold. Buying options and shorting lost. It covers one mostly rising market and is not advice.
Is extreme greed a sell signal?
Not in this test. On extreme-greed days (index 75 or over), a 30-stock basket held all the time earned $12.11 a day per $10,000, and the 200-day trend rule $16.73 — more than on greed days overall ($8.27 and $9.89). Shorting did not pay either: on greed days momentum shorts in index futures lost (t −4.3).
Do short strangles work?
On SPY from 2024 to 2026, a short strangle — selling a call and a put one expected move away — held about 3 trading days won 83% of the time on greed days and made +$111 per trade per contract, against +$18 on fear days. Only 2–6 of about 620 luck tests matched it. But the worst trade lost about $1,100 per contract, trades overlapped, and the 1-day version made only +$43.
Should you buy calls when the market is greedy?
Not in this backtest. On greed days a bought SPY call lost $42 per trade per contract and a bought put $110. Options looked cheaper on greed days (a 0.70% next-day move priced, against 1.00% on fear days), but prices moved even less than that.
Why do option sellers do better on greed days?
Because greed days are quiet. The options market priced a 0.70% next-day move for SPY on greed days against 1.00% on fear days, and the real moves were smaller still. SPY’s typical daily swing was 0.75% on greed days against 1.0–2.1% on fear days (2016–2026). A seller keeps the premium when the move stays small.
Does shorting work when the market is greedy?
No. In index futures on greed days, momentum shorts lost (t −4.3) and the night-day rule’s short side lost (t −3.4). Only the long side held: the night-day rule long only was positive in 7 of 8 test sets.
Does Fear & Greed improve a 0-DTE butterfly strategy?
The strongest rule in our 0-DTE broken-wing butterfly study made +$6,780 on extreme-fear days and lost $22,990 on greed-zone days. But in a search of 2.2 billion combinations of conditions, no Fear & Greed condition made a top-10 list, and the best combination stayed the same.
Is this investment advice?
No. It is a backtest of past prices for education. Selling options can lose many times the premium collected, and past results do not promise future ones.

How the test works
- The index: the stock market’s Fear & Greed index, 0 to 100, stored for every session since January 2011 (3,943 sessions to October 9, 2026). Each session uses the last reading known before it opened.
- Zones by the index’s own edges: extreme fear under 25, fear 25–45, neutral 46–54, greed 55–74, extreme greed 75 and over. “Greed days” means 55 and over; “fear days” means 45 and under.
- Options: SPY option prices on 678 trading days, January 29, 2024 to October 9, 2026. 16 structures opened at 10:30 New York time and held to expiry, at three expiries (same day, next, furthest stored ≈ 3 trading days); strikes set in expected moves (the at-the-money straddle’s price); the last trade taken as the mid; dollars per trade per SPY contract.
- Futures: 8 rules from our futures tools, each both ways, long only and short only, risking $900 a trade, on QQQ and SPY 1-minute bars 2016–2026 and real NQ, ES, YM and RTY futures 2024–2026; dollars per session.
- Stocks: daily bars of 30 stocks and ETFs, October 2016 to October 2026, in an equal-weight basket; dollars a day per $10,000.
- Butterflies: 432 replays (6 rules × 2 wing widths × 12 entry times × both sides, puts only or calls only) on the same 678 days, after fees, at mid prices.
- Luck checks: the zone labels shifted onto other days hundreds of times (about 620 for options); a result counts only if few shifted runs beat it. Both halves of each period checked separately.
