Compare Active and Passive Investing Strategies

The active versus passive argument is loud, confident, and full of people selling you something. This sets that aside and walks through what the research actually shows, why the answer is not as obvious as either side claims, and how the findings map onto your own situation, without naming funds or pretending to be regulated advice.

**Compare active and passive investing with evidence:**
1. Summarise the case for passive investing: the SPIVA data, expense ratio drag, and why most active managers underperform their benchmark after fees over 10-year periods
2. Summarise the legitimate case for active investing: market inefficiency in certain asset classes, skilled managers who do outperform (and why identifying them in advance is the hard part), and risk management benefits
3. Identify the conditions under which active approaches have the strongest historical case: small-cap, emerging markets, alternative assets
4. Give a practical framework for how an individual investor should weight the two approaches based on their time horizon, cost sensitivity, and specific asset classes
