What Is an Investment Philosophy?

The Definition

Investment Philosophy = Your core beliefs about how markets work and how you should invest

It answers:

  • Why am I investing?

  • What am I investing in?

  • How will I behave during different markets?

  • When will I buy/sell?

  • What are my non-negotiable rules?

It's NOT:

  • Specific stock picks (those change)

  • Market predictions (impossible)

  • Temporary strategies (those evolve)

It IS:

  • Timeless principles that guide decisions

  • Your belief system about investing

  • The rules you follow regardless of emotions or market conditions

Why You Need One

Without a philosophy:

  • ❌ Make random decisions based on news

  • ❌ Panic sell during crashes

  • ❌ FOMO buy at tops

  • ❌ No consistency

  • ❌ Emotions override logic

  • ❌ Poor long-term results

With a philosophy:

  • ✅ Clear framework for every decision

  • ✅ Emotional anchor during volatility

  • ✅ Consistent approach

  • ✅ Can explain why you own each investment

  • ✅ Better sleep at night

  • ✅ Superior long-term results

Your philosophy is the difference between guessing and executing a proven plan.

Philosophy #5: Hybrid Approach (Core + Satellite)

Core belief:

  • Combine safety of indexing with potential of active selection

  • Core provides stability and guaranteed average returns

  • Satellite allows for outperformance and learning

Approach:

  • 70-80% in index funds (core)

  • 20-30% in individual stock picks (satellite)

  • Core never changes

  • Satellite can be more active

Example:

  • Core: $70,000 in VOO/VXUS/BND (80%)

  • Satellite: $20,000 in 10 individual stocks (20%)

  • Satellite can try value, growth, dividend strategies

  • If satellite underperforms, core still doing well

Best for:

  • Intermediate investors

  • People who want to learn stock picking without too much risk

  • Desire for safety + excitement

  • Long time horizons (5+ years)
