Meaning
Durability bias makes people believe a current emotion or market condition will last longer than it usually does.
Indian Market Context
In a rally, investors may think optimism is permanent. In a crash, they may think recovery is impossible. Both reactions can damage long-term plans.
Example
After a sharp small-cap rally, an investor may increase risk just because recent gains feel durable.
Checklist for Investors
Use asset allocation, valuation discipline, and review dates. Do not make long-term decisions from short-term feelings.
How To Control This in Real Decisions
Behavioural mistakes are hardest to catch because they feel reasonable while they are happening. A useful Indian investor habit is to separate the story from the evidence. The story may come from a friend, business channel, Telegram group, or a recent price move. The evidence should come from numbers, filings, valuation, liquidity, and risk limits.
Before adding money, write one sentence each for why you are entering, what would prove you wrong, and how much loss you can accept. This simple record is powerful because it makes emotional decisions visible. It also helps during tax review, portfolio rebalancing, and conversations with advisers or family members who share the same financial goals.
