Familiarity Bias
Preferring investments one recognises, treating familiarity as a proxy for safety.

In depth
Familiarity feels like information and is not: recognising a brand tells you nothing about whether its shares are attractively priced, and consumer experience of a product is not analysis of a business. Its most dangerous form is employer stock concentration, where salary, bonus, options and portfolio all depend on one company — an exposure that fails entirely together. It also drives home bias and sector concentration in whatever industry the investor works in, compounding the correlation between income and portfolio. The countermeasure is to check what the portfolio is actually exposed to rather than what it feels comfortable holding.
Worked example
An employee holds 40% of their portfolio in employer stock alongside their salary and vested options. A serious problem at the company removes income, options and two-fifths of the portfolio at the same moment.

This entry explains what “Familiarity Bias” means. It is not investment advice and not a recommendation to buy or sell any security. Any numbers above are illustrative, not live prices, and nothing here predicts price direction or rates a stock. Consider your own circumstances and consult a SEBI-registered investment adviser before acting.
