ETFs in 10 minutes.

An ETF is a legal wrapper holding tens or hundreds of securities. When you buy 1 share of the ETF VFV.TO, you own a tiny fraction of the 500 companies in the S&P 500 — Apple, Microsoft, NVIDIA, JPMorgan, Coca-Cola, and so on. All in a single trade.

Three key differences from an ordinary stock:

• Automatic diversification — no need to buy 500 individual stocks.
• Passively managed (for most) — the ETF tracks an index mechanically, with no active manager.
• Liquid — you can buy/sell it all day like a stock.

Quick comparison: Buying all 500 S&P 500 stocks individually would cost absurd commissions (even at $0/trade, it's unmanageable). An ETF gives you the same exposure for ~0.03% in annual fees (VOO).

The MER (Management Expense Ratio) is the annual percentage the ETF issuer charges you. It is deducted automatically from the value of your shares — you never see it on your statement, but it is very much there.

A reference scale:

• Excellent: under 0.10% (VOO 0.03%, XIC 0.06%, ZAG 0.09%).
• Good: 0.10% to 0.25% (XAW 0.22%, XEQT 0.20%).
• Acceptable: 0.25% to 0.50% (some sector or hedged ETFs).
• High: over 0.50% — check that you're really getting more value.

The snowball effect of fees: Over 30 years with $100,000 initial at 7%/yr, a MER of 0.10% vs 1.00% costs you about $110,000 in cumulative fees. Fees compound just as returns do.

Good reflex: faced with an active ETF (MER 0.70%+), check whether it actually beats its passive benchmark over 10 years. Most do not.

1. What do I want exposure to? S&P 500 (VFV), TSX (XIC), diversified world (XEQT), dividends (VDY), bonds (ZAG), a specific sector (XLK for tech, XLE for energy)?
2. CAD or USD? On the TSX = CAD (no currency conversion); on NYSE/NASDAQ = USD. The currency choice depends on your reference currency and your broker's conversion fees.
3. Hedged or not? Hedged = protected against CAD/USD swings. If you're aiming for 10+ years: unhedged usually wins (fees and tracking are less than perfect). Short term: hedged can make sense.
4. What is the MER? Aim under 0.25% for core holdings. Specialised ETFs can justify more if the strategy is genuinely unique.
5. What is the AUM (fund size)? An AUM under $100M raises the risk of the fund closing (and of forcibly realising your gains). Aim for $500M+ for core holdings.

1. Buying 10 ETFs that do the same thing. VFV + VOO + XUS + XSP is the same S&P 500 under 4 wrappers. You think you're diversified; you're not. Pick ONE.
2. Chasing past returns. The Ark Innovation ETF (ARKK) was the darling of 2020, −80% in 2022. The last 5 years' tops often become the next 5 years' flops.
3. Ignoring a “thematic” ETF's MER. Cybersecurity, AI, cannabis and ESG ETFs often charge 0.50-0.80%. Over 30 years, that's $200,000+ lost on $100,000 initial.
4. Trading your ETF actively. An ETF is built to be held for years. Scalping it on 3-day cycles = commissions + slippage + turnover that kill your return.
5. Forgetting to rebalance. If VFV climbs 30% and XIC stalls, you no longer hold your 60/40 target. Rebalance once a year (or use an all-in-one ETF like XEQT that does it for you).
