Anchoring Bias

Anchoring bias happens when an investor gives too much importance to one number, such as a past high, purchase price, target price, or IPO price.

What It Means

Anchoring bias happens when an investor gives too much importance to one number, such as a past high, purchase price, target price, or IPO price.

Where It Shows Up In India

Indian retail investors often anchor to round prices like Rs 100, 500, or 1,000, to 52-week highs on NSE/BSE, or to the price at which a stock was popular on social media.

This matters because a bias can feel like common sense while quietly pushing an investor away from evidence. In Indian markets, the trigger may be an IPO rush, a familiar Nifty level, a WhatsApp forward, a recent fund ranking, or a loss in a Demat portfolio that is emotionally hard to accept.

Simple Example

If you bought a share at Rs 800 and refuse to review it until it returns to Rs 800, you may be anchored to your cost instead of the company’s current fundamentals.

How To Reduce The Damage

  • Write the reason for every buy, sell, or hold decision before placing the order.
  • Compare the current facts with the original thesis instead of only looking at price.
  • Use position sizing so one emotional decision cannot damage the whole portfolio.
  • Review official NSE/BSE filings, fund documents, and audited data before acting on social media.

Practical Takeaway

Use valuation, earnings, debt, cash flow, and risk rather than a single remembered price.

Good investing behaviour is not about removing emotion completely. It is about slowing the decision down enough for facts, valuation, risk, and time horizon to enter the room.
