Why Your Return Expectations Are Wrong: Optimism Bias | Behavioural Finance M2 Ep 9

Everyone Thinks the Market Will Reward Them. The Data Disagrees. Almost nobody enters an investment expecting it to fail. That quiet confidence feels harmless, but it shapes how much return you plan for, how much risk you take and how much cash you keep aside. Series: Behavioural Finance – The Foundations Module 2: The Taxonomy of Cognitive Biases Episode 9: Optimism Bias This episode looks at why the mind rates your own odds more kindly than the numbers do, and why that gap opens before you have invested a single rupee. By the end, you'll know how to replace a hopeful guess with a realistic starting point. In this video, you'll learn: ✅ Why expecting a better outcome for yourself than for others feels reasonable, even when the data says otherwise ✅ How optimism shows up in Indian markets: return expectations, IPO applications and F&O participation ✅ How to begin every decision with the base rate instead of a persuasive story ✅ How to size a position by the chance of being wrong, not by how strongly you believe ✅ Why a liquid emergency buffer belongs in place before you take market risk This is Episode 9 of a 10-part Module on cognitive biases, part of a larger 10-module Behavioural Finance series for Indian retail investors who want to understand why they make money mistakes, not just what mistakes to avoid. ▶ Module 2 Playlist:    • Behavioural Finance Course: Investor Psych...   ▶ Module 1 Playlist:    • Behavioural Finance Course: Investor Psych...   ⏱ Chapters: 0:13 The hook: a hopeful expectation 1:42 The concept explained simply 3:58 Example: The Return Expectation Gap 5:28 Example: Position Sizing and its Risk 6:58 What to do about it: key takeaways 9:52 Closing thought 📌 Quick facts: 1. Optimism bias is the tendency to expect better outcomes for yourself than the statistical base rate suggests. 2.

SEBI's earlier study covering FY22 to FY24 found that 93% of over 1.1 crore individual F&O traders lost money. 4. The Nifty 50 has delivered roughly 14–15% annualised returns over the past twenty years, with significant volatility along the way. 5. India's IPO market raised a record of about ₹1.95 lakh crore in 2025. ❓ Frequently asked: Q: What is optimism bias in investing? A: It is the habit of believing that good outcomes are more likely for you than for other investors, and bad outcomes less likely. It leads to high return expectations, thin risk planning and oversized positions. Q: Why do so many traders enter F&O when most of them lose money? A: Each new trader tends to believe their approach is different from those who lost before. Optimism bias lets people accept the published loss rate as true for others while assuming they personally sit in the winning minority. Q: What is a base rate, and why does it matter for investing? A: A base rate is how often an outcome happens across everyone in a similar situation, for example how often an IPO lists above its offer price or how often F&O traders make money. Starting from it keeps your expectations tied to evidence rather than hope. Q: How is optimism bias different from self-attribution bias? A: Optimism bias works before a decision, by inflating the odds you assign to success. Self-attribution bias works afterwards, by crediting wins to skill and blaming losses on outside factors. ⏮ Previously in Module 2: Episode 8, Status Quo Bias    • Why Your FD Keeps Auto-Renewing: Status Qu...   ⏭ Next in Module 2: Episode 10, Choice Overload    • The Real Reason You Never Started That SIP...   📌 Disclaimer: Content published here is for general information and educational purposes only and does not constitute an investment advice, a research report, or a solicitation to buy or sell any product.
