Stock picking is tactical. Portfolio construction is structural. Serious investors think in terms of risk budgeting.
1. Asset Allocation (Primary Driver of Returns)
Research Finding (Brinson, Hood & Beebower Study):
- • ~80–90% of long-term portfolio variability is explained by asset allocation
Decide: Strategic allocation (long term) + Tactical tilts (cycle-based)
2. Risk Management Metrics
Professional portfolios track:
- Standard Deviation
- Beta
- Sharpe Ratio
- Maximum Drawdown
- Value at Risk (VaR)
- ⚠️Retail investors ignore these at their own peril.
3. Market Cap Allocation
| Cap Size | Characteristics |
|---|---|
| Large Caps | Stability, Lower drawdown |
| Mid Caps | Growth acceleration |
| Small Caps | Illiquidity premium, Volatility premium |
💡 Balanced allocation reduces regret risk.
4. Sector Diversification
❌ Avoid
- • Overweighting cyclical sectors at peak
- • Thematic concentration
✓ Ensure
- • Economic representation
- • Earnings diversification
5. Rebalancing Discipline
- ✓Reduces behavioral bias
- ✓Enforces sell-high, buy-low
- ✓Controls portfolio drift
6. Tax Efficiency
India Tax Rates:
| Type | Rate |
|---|---|
| LTCG (Long Term Capital Gains) | 10% |
| STCG (Short Term Capital Gains) | 15% |
💡 High churn reduces post-tax alpha.
Key Takeaway
Portfolio construction is about survival first, growth second. If you avoid large drawdowns, compounding works better.
