Don’t Let The “Endowment Effect” Affect Your Trading Performance

You buy a stock, crypto, or forex pair. It starts falling, but instead of cutting losses, you hold on—convinced it will recover.

This is the endowment effect in action—a cognitive bias that makes us overvalue what we own, even when logic says we should let go.

In trading, this leads to:

Holding losers too long (hoping for a rebound)
Selling winners too early (fearing reversals)
Emotional decision-making instead of rule-based trading

This article will:
✔ Explain the psychology behind the endowment effect
✔ Show how it destroys trading accounts
✔ Provide actionable strategies to overcome it
✔ Highlight real-world examples of traders who failed (and succeeded)

What Is the Endowment Effect?

The endowment effect is a behavioral bias where people assign more value to things simply because they own them.

How It Applies to Trading:

“My trade will come back” → Refusing to exit losers
“I know this stock better” → Ignoring contrary signals
“I can’t sell at a loss” → Breaking risk management rules

Example:
A trader buys Bitcoin at 100K. When it drops to $50 K, in s t e a d o f c u tt in g l osses, t h ey h o l d s t u bb or n l y .” I t e v e n t u a ll y cr a s h es t o$ 30K—wiping out their capital.

Result: The trader overvalued their position due to ownership bias.

Why the Endowment Effect is a Silent Killer in Trading

1. It Makes You Ignore Stop-Losses

Traders move stop-losses wider to avoid realizing a loss.
This leads to catastrophic drawdowns.

2. It Clouds Objectivity

You start cherry-picking data that supports your bias.
You ignore technical breakdowns or fundamental shifts.

3. It Encourages Averaging Down (Often a Bad Idea)

“It’s cheaper now, so I’ll buy more!” → Doubling down on losers (e.g., AMC, GameStop bagholders).

4. It Creates Emotional Stress

Holding a losing trade consumes mental energy.
Leads to revenge trading or overtrading.

How to Overcome the Endowment Effect

1. Follow a Trading Plan (No Exceptions)

Define entry, exit, and stop-loss rules before entering a trade.
Use mechanical systems (e.g., algorithmic rules) to remove emotion.

Pro Tip: Our W.D. Gann Trading Strategies course teaches rule-based trading to eliminate emotional bias.

2. Treat Trading Like a Business, Not a Gamble

Would you keep investing in a failing business? No.
Apply the same logic—cut losses early.

3. Use Position Sizing & Risk Management

Never risk more than 1-2% per trade.
If a trade hits your stop-loss, exit immediately.

4. Review Your Trades Objectively

Keep a trading journal.
Ask: “Would I enter this trade again today?” If not, close it.

5. Understand Market Cycles & Sentiment

Markets move in cycles (bull runs, corrections, crashes).
Financial astrology can help identify turning points (e.g., Saturn retrograde periods often bring volatility).

Real-World Examples of the Endowment Effect in Trading

Case Study 1: The Bitcoin “Diamond Hands” Trap

Many traders held BTC from $t o$ 16K (2021-2022), refusing to sell due to emotional attachment.
Result: Massive losses that could’ve been avoided with strict exits.

Case Study 2: The GameStop (GME) Bagholders

Retail traders held GME from $t o$ 40, believing in a “short squeeze revival.”
Reality: The trade was over, but endowment bias kept them stuck.

Final Thoughts: Trade Without Attachment

The endowment effect is one of the biggest reasons traders fail. To succeed:
✅ Stick to your rules (no emotional overrides)
✅ Cut losses fast (let winners run)
✅ Review trades objectively (no attachment)
