The Decision Tree
A framework that replaces reactive decisions with process
The goal of a sentiment framework isn't to predict the market. It's to pre-commit to rational behavior at each level — so when fear or greed hits, you already know what to do. Concentrated holders make their most expensive mistakes when they decide in the moment rather than following a pre-established plan.
This framework uses the CNN Fear & Greed Index as the primary trigger (0–100 scale) because it's composite, freely available, and widely referenced. But the principles apply regardless of which indicator you use. The key is having thresholds defined before you need them.
Extreme Fear Zone (0–25)
What to do when the market is panicking
Extreme Fear readings occur roughly 10–15% of the time. Recent examples: March 2026 (tariff shock, F&G hit 13), October 2022, March 2020. These are periods when most investors want to sell — and historically, that's the worst time to do so. Buying when F&G is below 20 has produced above-average 12-month forward returns approximately 80% of the time.
DO NOT panic sell your concentrated position. This is statistically the worst time to sell — you're selling at depressed prices AND triggering capital gains tax
DO NOT assume 'this time is different.' Every extreme fear period feels like the world is ending. Most resolve within weeks to months
CONSIDER: Is this fear driven by temporary shock (tariffs, elections, geopolitics) or structural deterioration (your company's fundamentals)?
IF STRUCTURAL: Use the fear period to contribute shares to §721(a) SPV at current (lower) fair market value — lower valuation means more shares contributed per dollar of value
IF TEMPORARY: Hold through. Do nothing reactive. Review your framework at neutral
TAX-LOSS HARVEST: If you hold other positions at a loss, extreme fear is the ideal time to realize losses for tax offset
REBALANCE CASH: If you have cash reserves, deploy incrementally (not all at once) into diversified positions
The #1 Mistake in Extreme Fear: Selling a concentrated position in extreme fear to 'stop the bleeding.' A $3M NVDA position sold in March 2020 extreme fear would have triggered ~$400K in taxes and missed the subsequent 300%+ recovery. The same position sold during October 2022 fear would have missed a 200%+ recovery. Panic selling converts temporary drawdowns into permanent capital destruction via taxes. • Tax bill is permanent — market recoveries are not guaranteed but historically likely • You sell at maximum fear pricing — the worst price of the cycle • You likely won't buy back in time (you'll wait for 'confirmation' that misses the bottom)
Fear Zone (25–45)
Below neutral but not extreme — the planning window
Fear (but not extreme fear) is the optimal window for taking structural action. Prices are depressed from highs but not in freefall. Emotional urgency has subsided enough for rational planning. This is when concentrated holders should be most active in setting up structural changes.
Actions to Consider in Fear (25–45)
- Initiate §721(a) SPV contribution at lower fair market value (more shares, same value)
- Establish 10b5-1 selling plan for systematic future diversification
- Review and update estate planning (concentrated positions need special planning)
- If in trading window: sell short-term gain lots that create minimal tax impact
- Buy protective puts — they're expensive (high VIX) but this is when you need protection most
What NOT to Do in Fear Zone
- Wait for 'the bottom' before acting — nobody identifies bottoms in real-time
- Double down on your concentrated position because 'it's cheap now'
- Ignore the signal — fear zone means something is wrong or perceived to be wrong
- Make permanent decisions based on temporary headlines
Neutral Zone (45–55)
The maintenance window — prepare for extremes
Neutral sentiment is the calm between storms. Neither fear nor greed is driving decisions. This is the ideal time for maintenance actions — things you should do regardless of direction, but that feel less urgent (and therefore get delayed) in calm markets.
Review concentration percentage: Has your stock appreciated enough to increase concentration above your threshold?
Check trading window calendar: When is the next open window? Plan structural actions in advance
Update your personal framework: What are your thresholds for action? At what loss level does your financial plan break?
Evaluate §721(a) contribution timing: Neutral periods offer fair valuations without panic or euphoria distortion
Assess hedging costs: VIX in neutral (15-20) makes protective options reasonably priced
Document your plan: Write down what you will do at F&G 20 and F&G 80 — so you follow process, not emotion

Greed Zone (55–75)
Rising optimism — the window is shrinking
Greed (but not extreme) means the market is rising and optimism is building. Your concentrated position is likely at or near highs. This feels good — which is exactly why it's dangerous. The euphoria makes every structural decision feel like 'selling too early.' But if you're going to take action, better during greed (high prices, fair valuations) than waiting for the next fear cycle.
Take Partial Action
You don't need to sell everything or contribute all shares at once. In the greed zone, consider contributing 25–40% of your concentrated position to a §721(a) SPV. This locks in income generation on a portion while maintaining upside on the remainder. If greed continues, you still participate. If it reverses, a portion is now structurally protected.
Sell High-Cost Lots
If any of your shares were acquired at prices near current levels (recent RSU vests, ESPP purchases), the greed zone is ideal for selling these specific lots — minimal capital gains, reduces concentration, provides liquidity for diversification.
Costless Collars Become Attractive
When your stock is elevated and VIX is moderate, zero-cost collar options (sell upside call + buy downside put) become more attractive. You give up some additional upside but gain concrete downside protection. Only works if you have enough shares to meet options contract minimums.
Extreme Greed Zone (75–100)
Euphoria — this is when mistakes are most expensive
Extreme Greed readings above 75 occur roughly 15% of the time. Extreme greed doesn't mean the market crashes tomorrow — it can persist for weeks or months. But it means risk/reward has shifted unfavorably: the easy gains are behind you, and the potential for mean-reversion correction is elevated.
For concentrated holders, extreme greed is the most psychologically dangerous zone because everything feels perfect. Your stock is at highs. Your net worth is at highs. Every decision to diversify feels premature. 'Why would I sell something that's working?' But this is precisely when structural decisions have the most favorable math — you're contributing shares at high valuations, locking in gains without tax, and creating income streams from elevated positions.
The #1 Mistake in Extreme Greed: Adding to your concentrated position because 'my stock only goes up.' Tech employees frequently exercise options, buy via ESPP, and hold all RSU vests during extreme greed — increasing concentration at the worst possible prices. Every share added at the top of a greed cycle has maximum distance to fall. • Selling even a portion feels like 'betraying' your company's mission — it's not, it's financial planning • FOMO from colleagues holding everything creates social pressure to maintain concentration • The regret of missing further upside feels worse than the regret of being concentrated during a crash — until the crash happens
Rational Actions in Extreme Greed
- Contribute shares to §721(a) SPV at elevated fair market value — you're 'locking in' high valuations as income-generating base
- Sell short-term gain lots for minimal tax impact — prices are high, so even short-term lots may be worth the tax
- Establish or tighten stop-loss levels (knowing they won't protect against overnight gaps)
- Max out diversification in retirement accounts (401k, IRA) even if taxable account stays concentrated
- Document your 'if it drops 20% from here' plan — because it will eventually
What NOT to Do
- Add to your concentrated position (no exercising options, no ESPP purchases, no buying more shares)
- Assume elevated prices are the 'new normal' — mean reversion is real
- Delay structural decisions because 'it might go higher' — you can always contribute more later
- Compare yourself to colleagues who are holding everything — they're taking risk you don't need to take
Common Mistakes by Zone
What costs concentrated holders the most money
| Zone | Costliest Mistake | Estimated Cost |
|---|---|---|
| Extreme Fear (0–25) | Panic selling at the bottom | $400K+ in taxes + missed recovery on $3M position |
| Fear (25–45) | Doing nothing — paralysis | Missed opportunity to contribute at low valuations |
| Neutral (45–55) | Complacency — not preparing a plan | No framework when the next extreme arrives |
| Greed (55–75) | Thinking structural changes are 'premature' | Contributing at lower valuations later costs more concentration |
| Extreme Greed (75–100) | Adding to position at highs | $200K+ max drawdown per $1M added at peak |
FAQ
Frequently Asked Questions
What if I missed the last fear period — should I wait for the next one?
No. Waiting for a specific sentiment level to take action is itself a timing strategy — and timing strategies fail. The entire point of a sentiment framework is to define what you'll do at each level, not to wait for a specific level before starting. If you're currently in the neutral or greed zone and haven't taken structural action on your concentration, the rational choice is to act now — not wait for fear. Extreme fear may not arrive for months or years, and your concentration risk persists every single day regardless of the Fear & Greed reading. The best time to plant a tree was 20 years ago. The second-best time is today.
How do I know if a fear reading is 'bad enough' to buy or 'good enough' to stop worrying?
You don't — and that's why a process-based approach beats a threshold-based one. Instead of waiting for a specific number, use zones: below 25 means no selling (statistically terrible time), above 75 means no adding (statistically dangerous). Between 25–75, your actions should be structural and gradual rather than reactive and binary. The research is clear: nobody consistently identifies exact tops or bottoms. The investors who do best over decades are those who follow consistent processes — contributing to income structures, rebalancing at regular intervals, and avoiding emotional extremes.
Should my framework be different because I work at my concentrated stock's company?
Yes — your framework should be more aggressive about reducing concentration at every level. Here's why: your human capital (salary, bonus, unvested RSUs, career trajectory) is already correlated to the same company. A diversified outside investor holding NVDA stock has a career income uncorrelated to NVIDIA's performance. An NVIDIA employee holding NVDA stock has career income, vesting schedule, and portfolio all correlated. This means your 'true concentration' is higher than your stock percentage suggests. If your stock is 50% of your liquid net worth, your 'effective concentration' including human capital correlation is closer to 60–70%. This argues for taking structural action at lower thresholds than an outside investor would.
Can I just follow the contrarian signal and buy extreme fear / sell extreme greed?
The contrarian signal works for diversified portfolios (buying the S&P 500 at extreme fear has historically excellent 12-month returns). But for a concentrated single-stock holder, 'buying extreme fear' means adding to an already-concentrated position at what might not be the bottom for your specific stock. Company-specific risk (accounting fraud, product failure, leadership change) doesn't follow market-wide sentiment cycles. Your company could be in extreme fear for fundamental reasons. The safer contrarian application for concentrated holders: don't sell in extreme fear (avoid the tax hit at the worst price), and don't add in extreme greed (avoid increasing concentration at the worst valuation). For new capital deployment, buy diversified assets — never increase concentration.
