Anchoring

Kahneman and Tversky once had people spin a wheel of fortune — secretly rigged to land on 10 or 65 — then asked them an unrelated factual question: what percentage of UN countries are African? People who saw 10 guessed low (~25%); people who saw 65 guessed high (~45%). A visibly random number bent a factual estimate. That's anchoring: the mind grabs the first available number and adjusts from it — insufficiently, always.

Markets are wall-to-wall anchors, and three of them run more retail decisions than any analysis does:

Your buy price — the emperor of anchors. It's a historical accident, personal to you, invisible and irrelevant to the market — yet it silently becomes the reference for everything: "I'm down 12%" (from the anchor), "I'll sell at breakeven" (return to the anchor), "it's cheap now, I'll average" (cheap relative to the anchor). The disposition effect (Chapter 3) is loss aversion steering by this anchor. One sentence worth engraving: the market has never heard of your price.

The 52-week high/low — "it's fallen 60% from the top, how much lower can it go?" (Answer, as every bear market teaches: much. A stock down 60% is a stock that went down 60% — the old high was one moment's opinion, not a value.) Your FA school warned that a fallen price isn't margin of safety; anchoring is why the trap feels safe: 60%-off feels like a sale because the anchor says the "real" price is the old high.

Round numbers and recent levels — Nifty at 25,000, a stock at ₹1,000, yesterday's high. These anchors are at least shared — which upgrades them from personal illusion to structural reality: because thousands of traders anchor there, orders cluster there, which is exactly your Market Structure school's order-address chapter. Note the beautiful distinction: your buy price is a private anchor (pure bias, zero market meaning); round numbers are public anchors (bias so widely shared it becomes real order flow). Respect the second kind; fire the first.

Defense — replace the anchor's questions. Anchoring can't be deleted, but its question can be swapped: never "am I up or down from my price?" but "what does the position deserve at today's price, today's structure, today's facts?" Practical devices: (1) the Fresh-Money Test (Chapter 3) — re-underwrite ignoring your entry; (2) set exits off market references (structure levels, thesis conditions, trailing rules), never off breakeven or round-trip-to-my-price; (3) in analysis, compute value before looking at price (your FA school's DCF-then-compare order exists partly to keep the market's number from anchoring your estimate).

Offense — trade the public anchors. Breakeven clusters of trapped buyers create the support-becomes-resistance flip; round numbers hold visible depth and stop pools; prior highs attract both. The disciplined trader treats public anchors as maps of other people's reference points — knowing the crowd navigates by these landmarks tells you where their orders, and their mistakes, are parked.
