🧩 Step 1: Define your goals and timeline

Before choosing investments, define:

  • How long you plan to invest (short, medium, or long term)

  • What's your objective (growth, income, or stability)

  • How much volatility you can handle

📊 Example:

If you're investing for 10+ years → you can afford more stocks.

If it's less than 3 years → keep more bonds or cash.

💼 Step 2: Choose your core asset classes

🔁 Step 4: Rebalance periodically

  • Review every 6 to 12 months

  • Sell overperformers, buy undervalued assets

  • Keep your risk profile aligned

💡 Example:

If stocks grow from 60% to 75% of your portfolio → sell a small portion and rebalance.

🧠 Step 5: Stay consistent — not reactive

The biggest enemy of investors isn't the market — it's emotion.

Stick to your plan. Focus on long-term compounding, not daily fluctuations.

Q&A

How often should I rebalance?

Once or twice a year, or if your allocation changes by more than 5–10%.

Can I build a diversified portfolio with ETFs only?

Yes — broad ETFs (World, S&P 500, Bonds, REITs) offer instant diversification.

Frequently Asked Questions

What's the ideal portfolio for beginners?

A simple 60/40 mix (60% global equities, 40% bonds or cash) is a great start.

How do I measure diversification?

Check correlation between assets — the lower it is, the better.

Where can I analyze companies or ETFs easily?
