Anchoring in Investment Decisions (Deep-Dive)

Anchoring is the cognitive bias where an initial reference number disproportionately influences subsequent estimates or decisions — even when the anchor is arbitrary or irrelevant. In investing, anchors silently shape buy, sell, and target-price decisions.

Common investing anchors: (a) Purchase price — "I'll sell when it gets back to my cost"; (b) 52-week high/low — mistaking the recent high as a target; (c) Round numbers — selling at Rs 1,000 because it's a round figure; (d) IPO price — valuing the company relative to its issue price years after listing; (e) Broker's first target — future revisions get anchored to it.

Anchoring is particularly damaging in two scenarios: (1) refusing to sell a losing position because of the purchase-price anchor (related to disposition effect), and (2) overpaying for a stock that has fallen from a high anchor because it "looks cheap relative to peak".

Example 1: An investor buys ABC Ltd at Rs 1,200. The stock falls to Rs 800 over two years on deteriorating fundamentals. The investor refuses to sell because "I'll wait for Rs 1,200". The anchor (Rs 1,200) is irrelevant; the only question is the forward-return outlook from Rs 800.

Example 2: XYZ stock fell from Rs 2,000 to Rs 1,200. A retail investor buys because "it's 40% off the high". Six months later, it's at Rs 800. The Rs 2,000 anchor created a false signal of value; the company's intrinsic value was Rs 700 all along.

Defence: Always evaluate a holding as if you owned no shares and were considering buying it today at current price. If the answer is no, sell.
