Individual investors invested in International Consolidated Airlines Group S.A. (LON:IAG) copped the brunt of last week's UK£724m market cap decline

Ownership Structure of International Consolidated Airlines Group: Individual investors hold 59% of the shares, giving them significant influence over management decisions, while institutions own 15% and private companies hold 27%.

Impact of Shareholder Composition on Performance: The lack of majority ownership by any single entity suggests a diverse shareholder base, but also indicates potential volatility if institutional sentiments shift; insiders own less than 1% of the company.
