The Anchoring Effect

🧭 Background & Context The anchoring effect describes the cognitive bias in which people rely too heavily on an initial piece of information (the „anchor“) when making decisions, even if that information is irrelevant or arbitrary. In an economic context, it occurs, for example, when a stock price falls from 100 euros to 80 euros: investors often perceive the 80 euros as „cheap“ simply because the anchor was at 100 – even though fundamental valuation suggests a fair value of 60 euros. This is particularly dangerous for retail investors, as they unconsciously use price targets, purchase prices, or historical highs as benchmarks, leading them to systematically buy too expensively or sell too early. The significance lies in the fact that the anchor distorts rational risk-benefit assessment and leads to losses when the market moves away from the anchor. A conscious approach – such as pre-defined entry and exit criteria or ignoring daily highs – can defuse this trap. Those who know about the effect check every decision against current fundamentals rather than past price points. 🔍 How It Works in Detail The anchoring effect describes how our brain is strongly influenced by a number or piece of information mentioned first when making decisions – even if it is completely arbitrary. This „anchoring“ works because, in times of uncertainty, we orient ourselves toward the first available reference point and then adjust insufficiently from there. A classic example: if a seller names a high price, subsequent lower offers automatically appear cheap, even though they may objectively be expensive. The effect also works without conscious perception, such as with discounts, salary negotiations, or the assessment of probabilities. Crucially, the anchor does not need to be logically justified – it merely sets a mental reference point from which we find it difficult to detach. Those who understand this mechanism can either use it deliberately or consciously defend themselves …
