1. Index Fund என்னன்னு?

Index Fund என்பது ஒரு specific Market Index-ஐ — Nifty 50, Sensex — exactly copy பண்ற, Passively managed Mutual Fund. Fund Manager stocks 'pick' பண்ண மாட்டார். Index-ல எந்த companies இருக்கோ, அதே companies-ல same weight-ல invest பண்றார்.

💡 Key Idea

Index Fund Market-ஐ beat பண்ண try பண்ணாது. Market-ஐ Match பண்ணும்.
