ETF Investment For Beginners Chapter 2 – ETF Selection: Choosing the Best Core Foundations

2.1 Why Care about ETF Structure & Costs

When you’re serious about long-term growth and swing returns, not all ETFs are created equal—even if they track the same market index.

• Expense Ratio (Total Expense Ratio or TER)
  This annual fee is deducted daily and compounds over time. While some broad-market ETFs charge < 0.05%, specialized, thematic, or leveraged funds may charge > 1 %—a cost difference that can amount to tens of thousands over decades.

• Tracking Error & Difference
  This measures how closely an ETF replicates its underlying index. Tracking error is the variance over time; tracking difference is the cumulative return gap. Low TER often means low tracking difference—but rebalancing friction or sampling strategies can add slippage. The best ETFs usually have < 0.2 % tracking error.

• Replication Method

  • Physical ETFs purchase the actual holdings. This is transparent but can lead to extra costs in global or low‑liquidity markets.

  • Synthetic ETFs use swaps or derivatives, often achieving tighter tracking and lower costs in hard-to-access markets (e.g. emerging markets), but they carry counterparty and regulatory risks .

2.2 Core Selection Criteria Checklist

When building your core ETF sleeve, evaluate each candidate through this framework:

1. Expense Ratio vs. Peers
   Compare TERs among ETFs tracking the same index. Aim for the lowest-cost option with proven reliability.

2. Tracking Quality
   Review historical tracking error/difference. Institutional issuer sites or providers like iShares & Vanguard publish these stats.

3. Liquidity
   Look at average daily volume, assets under management (AUM), and bid–ask spreads. Larger funds typically trade continuously and cost-effectively .

4. Replication Structure
   Decide physical vs synthetic. Synthetic may be advantageous for emerging markets but comes with complexity and counterparty risk.

5. Underlying Index & Scope
   Understand the index rules—e.g. equal-weight vs cap-weight, sector bias, rebalancing frequency. This impacts return behavior.

6. Tax and Domicile Considerations
   Depending on your region, dividend withholding, treaty, and accumulation vs distribution structure can make a pay‑off.

2.4 Tool-Agnostic Evaluation Steps

1. List 2–3 ETF options per category
   e.g.

   • US Large-Cap: ETF-A, ETF-B

   • Emerging Markets: ETF-C (physical), ETF-D (synthetic)

2. Gather key data

   • TER

   • AUM; daily volume; average bid–ask spread

   • Tracking error/difference

   • Replication method + domicile

   • Underlying index methodology

3. Score each candidate
   Rank by: cost + tracking + liquidity + transparency.
   Top-ranking funds form your core portfolio.

2.5 Swing-Trading Considerations in ETF Selection

Since you’re layering swing trades atop your core:

• Choose ETFs with tighter spreads and liquid markets so entries and exits don’t bleed value.

• Avoid obscure thematic ETFs for swing trades unless they offer clear momentum triggers and enough volume.

• For options exposure or leveraged strategies, only use well-known, high-volume ETFs with rigorous stop discipline.

---

2.6 Quarterly Review & Adjust

Every quarter, revisit your selections:

• Have TERs changed?

• Is tracking error stable or trending worse?

• Has liquidity dried up?

• Are there new smarter ETF launches in the same space?

If performance, cost, or liquidity worsens, consider replacing an underperforming fund. Stay aware that ETFs do shut down when AUM dips—investopedia tracked ~622 global liquidations in 2024.
