Why Build an IPO Portfolio?

Instead of treating each IPO as an isolated bet, building a portfolio approach to IPO investing can improve risk-adjusted returns and provide more consistent results over time.

Portfolio Approach Benefits

Diversification

  • Reduces impact of any single IPO failure
  • Spreads risk across sectors and time periods
  • Smoothens overall returns

Systematic Process

  • Clear allocation rules
  • Emotional detachment from individual IPOs
  • Consistent decision-making

Better Tracking

  • Measure overall IPO performance
  • Identify what works for you
  • Continuous improvement

Allocation Framework

Overall IPO Allocation

Determine what portion of total investments go to IPOs:

  • Conservative: 5-10% of portfolio
  • Moderate: 10-20% of portfolio
  • Aggressive: 20-30% of portfolio

IPOs are higher risk, so limit overall exposure.

Per-IPO Allocation

Limit exposure to each IPO:

  • Maximum 20-25% of IPO allocation per IPO
  • Prevents concentrated bets
  • Allows participation in multiple IPOs

Sector Diversification

Avoid Sector Concentration

  • Don't put all IPO capital in one sector
  • Tech IPO boom doesn't mean ignore other sectors
  • Sector rotation can hurt concentrated portfolios

Suggested Sector Limits

  • Maximum 40% in any single sector
  • Try to have 3-5 sectors represented
  • Include defensive and growth sectors

Strategy Diversification

Mix of Approaches

Balance between:

  • Listing Day Exits: Quick profits, capital recycling
  • Short-Term Holds: 1-6 months for better returns
  • Long-Term Investments: Multi-year compounding

Suggested Split

  • 40-50%: Listing day exit strategy
  • 30-40%: Short-term holds
  • 20-30%: Long-term investments

IPO Selection Criteria

Tiered Selection System

Tier 1: High Conviction (30-40% of IPO capital)

  • Strong fundamentals
  • Reasonable valuation
  • Quality management
  • Apply with maximum allocation
  • Plan for long-term holding

Tier 2: Moderate Conviction (40-50% of IPO capital)

  • Good companies with some concerns
  • Fair valuation
  • Apply with moderate allocation
  • Flexible exit timing

Tier 3: Tactical (10-20% of IPO capital)

  • GMP-driven opportunities
  • Listing day plays
  • Smaller allocations
  • Quick exit planned

Risk Management

Position Sizing

  • No single IPO should be able to significantly impact overall wealth
  • Account for allotment probabilities when planning
  • Keep reserve capital for opportunities

Stop Loss Policy

For holdings beyond listing day:

  • Set stop loss levels (e.g., 15-20% below purchase)
  • Review and exit if thesis breaks
  • Don't hold losers indefinitely

Profit Booking Rules

  • Book partial profits at predefined levels
  • Let winners run with trailing stops
  • Rebalance periodically

Capital Management

Reserve Capital

Don't deploy all capital immediately:

  • Keep 30-40% as reserve
  • Deploy for high-conviction opportunities
  • Avoid being fully invested before best IPOs

Recycling Capital

  • Exit proceeds fund future applications
  • Maintain liquidity for upcoming IPOs
  • Compound returns by staying active

Performance Tracking

Metrics to Track

  • Overall Return: Total profit/loss from all IPO investments
  • Win Rate: Percentage of profitable IPO investments
  • Average Gain/Loss: Average profit on winners vs losers
  • Allotment Rate: How often you get allotment
  • Strategy Performance: Returns by strategy type

Regular Review

  • Monthly portfolio review
  • Quarterly strategy assessment
  • Annual performance analysis
  • Compare with benchmarks (Nifty, other IPOs)

Building Gradually

For Beginners

  1. Start with 2-3 IPOs
  2. Use single lot applications
  3. Learn from outcomes
  4. Gradually increase allocation

For Experienced Investors

  1. Implement full framework
  2. Optimize based on historical data
  3. Adjust strategies based on market cycles

Conclusion

A portfolio approach to IPO investing brings discipline, diversification, and systematic decision-making. Rather than betting big on individual IPOs, spread capital across multiple opportunities with varying strategies. Track performance, learn from outcomes, and continuously refine your approach. Remember, successful IPO investing is a marathon, not a sprint.
