Anchoring Bias — Definition and Examples in Finance

Quick Answer

Anchoring bias is a cognitive error in which the first piece of information you receive disproportionately influences your subsequent decisions, becoming an "anchor" around which you build your assessment. It works because the brain seeks reference points, so once it finds one — even a random one — all later estimates "drift" toward it, as shown in the classic Kahneman and Tversky wheel-of-fortune experiment. In finance it matters because it makes investors cling to a purchase price, an all-time high, or an initial offer, distorting decisions about when to sell, what is a fair price, and how to negotiate.

Definition

Anchoring bias is a cognitive error where the first piece of information we receive disproportionately influences our subsequent decisions. This first piece of information becomes an "anchor" around which we build our assessment.

How it works?

Our brain looks for reference points. Once it finds one — even if it's random — all subsequent estimates "drift" toward it.

Classic Kahneman and Tversky experiment: participants spun a wheel of fortune (results: 10 or 65), then estimated the percentage of African countries in the UN. Those who got 65 gave significantly higher estimates — despite the wheel having nothing to do with the question.

Examples in finance

Stock purchase price

You bought stock at $100. It dropped to $60. You don't sell because your anchor is $100 — "I'll wait until it returns to 100." Meanwhile, company fundamentals might have changed and $60 is the real value.

Real estate prices

"This apartment cost $300,000 a year ago, now it's $350,000 — expensive!" But if the apartment is worth $400,000 in current market conditions, $350,000 is a deal. Your anchor (300k) prevents objective assessment.

Salary negotiations

Employer offers $80,000. Even if you wanted $120,000, now you negotiate "from $80,000 up" instead of "from $120,000 down." The anchor shifted the entire negotiation.

Promotions and sales

"Regular price: $500, now: $299!" — $500 is the anchor. You don't check if the product is worth $299. You feel like you're saving $201.

ATH (All-Time High) as anchor

Stock reached ATH $200. Dropped to $120. Investors think: "cheap, because it was at $200." But $200 might have been a bubble, and $120 is above real value.

How to defend yourself?

1. Seek multiple reference points — don't rely on one number
2. Do your own analysis — calculate fundamental value instead of looking at historical price
3. Ignore purchase price when deciding to sell — current value and future prospects matter
4. Beware of "deals" — promotion isn't a reason to buy if you don't need the product
5. In negotiations: throw the anchor first — whoever gives the first number controls the conversation

FAQ

What is anchoring bias in simple terms?

Anchoring bias is a cognitive shortcut where the first number or piece of information you encounter disproportionately shapes your later judgments. In finance it often shows up as fixating on a purchase price, all-time high, or initial offer, even when newer data is more relevant.

Why does anchoring bias matter for investors?

It can lead to holding losing positions too long ("I'll sell when it gets back to my entry price") or rejecting fair valuations because they differ from a historical anchor. Recognising the effect is the first step toward making decisions based on current fundamentals rather than past reference points.

How can I tell if I am being anchored?

Ask yourself whether your target price, sell point, or "fair value" estimate would change if you had never seen the original number. If removing the anchor would materially shift your view, the anchor is likely doing the work, not your analysis.

Are professional investors immune to anchoring bias?

No. Research on analysts and portfolio managers shows anchoring affects price targets, earnings forecasts, and negotiation outcomes even among experienced professionals. Structured checklists and pre-committed decision rules can reduce, though not eliminate, the bias.
