Prinsip Diversifikasi

Mengapa Diversifikasi Penting?

“Don’t put all your eggs in one basket”

Diversifikasi mengurangi risiko karena:

• Tidak semua aset bergerak searah
• Kerugian di satu aset dioffset oleh keuntungan di aset lain
• Mengurangi volatilitas portofolio secara keseluruhan

Jenis Diversifikasi

1. Asset Class Diversification

   • Saham, obligasi, properti, emas

2. Geographic Diversification

   • Domestik vs internasional

3. Sector Diversification

   • Technology, healthcare, finance, consumer

4. Time Diversification

   • Dollar cost averaging

5. Strategy Diversification

   • Growth, value, income, index

Korelasi Antar Aset

Idealnya: Kombinasikan aset dengan korelasi rendah atau negatif

Asset Allocation

Apa Itu Asset Allocation?

Asset allocation adalah strategi membagi investasi ke berbagai asset class berdasarkan:

• Goals
• Time horizon
• Risk tolerance
• Financial situation

Model Asset Allocation

1. Age-Based Allocation

Stock allocation = 100 - Usia

Contoh:
- Usia 25: 75% saham, 25% obligasi
- Usia 40: 60% saham, 40% obligasi
- Usia 60: 40% saham, 60% obligasi

2. Risk-Based Allocation

3. Goals-Based Allocation

Tujuan: Dana pensiun 20 tahun lagi
→ Long term, bisa agresif
→ 70% saham, 25% obligasi, 5% emas

Tujuan: DP rumah 3 tahun lagi
→ Short term, harus konservatif
→ 20% saham, 50% obligasi, 30% cash

Strategic vs Tactical Allocation

Strategic (Passive):

• Set allocation sekali
• Rebalance periodic
• Buy and hold

Tactical (Active):

• Adjust allocation berdasarkan market conditions
• Overweight/underweight certain assets
• Requires market timing skill

Membangun Portofolio

Step 1: Define Goals

Tentukan tujuan investasi:

• Retirement fund
• Pendidikan anak
• Dana darurat
• Wealth building
• Passive income

Step 2: Assess Risk Tolerance

Pertanyaan untuk self-assessment:

1. Jika portofolio turun 20% dalam sebulan, Anda akan:

   • a) Panic sell semua
   • b) Khawatir tapi hold
   • c) Melihat sebagai buying opportunity

2. Investment horizon Anda:

   • a) < 3 tahun
   • b) 3-10 tahun
   • c) > 10 tahun

3. Income stability Anda:

   • a) Tidak stabil
   • b) Cukup stabil
   • c) Sangat stabil (PNS, BUMN)

Semakin banyak jawaban c, semakin tinggi risk tolerance.

Step 3: Determine Allocation

Berdasarkan goals dan risk tolerance:

Contoh: Investor 30 tahun, moderate risk, pensiun 30 tahun lagi

Target Allocation:
- Saham domestik: 40%
- Saham global: 15%
- Obligasi: 25%
- Reksa dana: 10%
- Emas: 5%
- Cash: 5%

Step 4: Select Investments

Untuk setiap asset class, pilih instrumen spesifik:

Saham domestik (40%):

• Blue chips: 25%
• Mid caps: 10%
• Small caps: 5%

Saham global (15%):

• US market ETF: 10%
• Emerging market: 5%

Obligasi (25%):

• SBN (ORI/SR): 15%
• Corporate bonds: 10%

Dll…

Step 5: Execute & Monitor

• Beli sesuai allocation
• Set up automatic investment (DCA)
• Monitor quarterly
• Rebalance annually atau saat deviation > 5%

Strategi Portofolio

1. Core-Satellite Strategy

Core (70-80%):
- Index funds
- Blue chip stocks
- Government bonds
→ Stable, long-term holdings

Satellite (20-30%):
- Individual stocks
- Sector funds
- Alternative investments
→ Potential higher returns, higher risk

2. Barbell Strategy

Conservative End (50%):
- Cash
- Short-term bonds
- Money market

Aggressive End (50%):
- Growth stocks
- Emerging markets
- High-yield bonds

Skip the middle:
- Avoid intermediate-risk assets

3. All-Weather Portfolio

Ray Dalio’s concept:

- 30% Stocks
- 40% Long-term bonds
- 15% Intermediate bonds
- 7.5% Gold
- 7.5% Commodities

Designed to perform in any economic environment:
- Inflation
- Deflation
- Rising growth
- Declining growth

4. Dividend Portfolio

Focus on income-generating assets:

- Dividend stocks: 50%
- REITs: 20%
- Bond funds: 20%
- Preferred stocks: 10%

Target: 4-6% annual yield

Rebalancing

Mengapa Rebalancing Penting?

Seiring waktu, allocation berubah karena performa berbeda:

Original (Jan):
- Saham: 60% (Rp 60 juta)
- Obligasi: 40% (Rp 40 juta)

After 1 year (Dec):
- Saham naik 30%: Rp 78 juta (66%)
- Obligasi naik 5%: Rp 42 juta (34%)

→ Now overweight saham, underweight obligasi
→ Need to rebalance

Kapan Rebalance?

Time-based:

• Quarterly
• Semi-annually
• Annually

Threshold-based:

• When deviation > 5%
• When deviation > 10%

Cara Rebalance

Option 1: Sell high, buy low

Jual saham: Rp 78 juta × 6% = Rp 4.68 juta
Beli obligasi: Rp 4.68 juta

New allocation:
- Saham: Rp 73.32 juta (61%)
- Obligasi: Rp 46.68 juta (39%)

Option 2: New contributions

Monthly investment: Rp 5 juta
Direct semua ke obligasi sampai balanced

Option 3: Withdrawals

Butuh dana? Withdraw dari asset yang overweight

Rebalancing Considerations

• Tax implications (capital gains)
• Transaction costs
• Avoid over-rebalancing
• Consider dalam tax-advantaged accounts
