Frequently Asked Questions About Martik Finance ETF Selection Framework
21 answers covering everything from basics to advanced usage.
// Basics
What does 'passive' mean when it comes to ETFs?
A passive ETF is designed to track a specific index — like the S&P 500 — without a fund manager actively picking stocks. Because there's no active management, the expense ratio is dramatically lower (0.03%–0.3%), and long-term returns aren't diluted by high fees or inconsistent manager decisions. Passive ETFs are the simpler, lower-cost default for most beginners.
What is an expense ratio and why does it matter so much?
The expense ratio is the annual fee automatically deducted from an ETF's value — you never see a charge, but your return is quietly reduced. It matters enormously over decades: a 1% fee compounds against you and can seriously eat into long-term gains compared to a 0.03%–0.3% passive ETF. Always compare fees before buying.
What are the four market exposure types in this framework?
The four types are: US Market ETFs (broad, established, ~8–10% historical average, lower volatility), International Market ETFs (developed markets outside the US for geographic diversity), Emerging Market ETFs (higher growth potential in fast-growing countries, higher volatility), and Small Cap ETFs (smaller companies with high potential and more volatility). A diversified portfolio typically combines more than one.
What is a fact sheet and why should I read it?
A fact sheet is a fund document disclosing an ETF's actual holdings, sector breakdown, geographic exposure, strategy, and expense ratio. Reading it tells you what's truly inside the basket before you buy — which companies, sectors, and regions you're exposed to. It's the single best way to catch index overlap and confirm the ETF matches your intended diversification.
// How To
How do I decide between accumulating and distributing ETFs for my country?
First ask whether you want regular income (distributing) or maximum compounding growth (accumulating). Then check your country's tax treatment: in many jurisdictions, accumulating ETFs are more tax-efficient because dividends aren't taxed until you sell, not on receipt. This is jurisdiction-dependent, so verify locally or with a tax professional before choosing a share class.
How do I calculate the real-money cost of an ETF's expense ratio?
Multiply the expense ratio by your intended investment amount. For example, $1,000 invested at a 0.05% expense ratio costs $0.50 per year, while the same $1,000 at 1% costs $10 per year. Doing this for candidate ETFs makes the abstract percentage concrete and highlights how much you save by choosing low-cost passive funds.
How do I check for index overlap between two ETFs?
Read each ETF's fact sheet and compare their geographic and holdings breakdowns. A common trap: an MSCI World ETF already contains roughly 70% US exposure, so stacking a pure US ETF on top creates heavy concentration, not diversification. Quantify the overlap and adjust your position sizes so you're genuinely spreading risk across regions.
How do I build a diversified beginner portfolio with ETFs?
Establish your goal, horizon, and risk tolerance, then combine at least two of the four market exposure types — for example a core US market ETF plus an international ETF, with an optional small emerging markets allocation if your horizon is long. Verify expense ratios stay in the 0.03%–0.3% range, choose your share class for tax efficiency, and check fact sheets for overlap.
How do I pick a brokerage to buy ETFs?
Evaluate brokerages on ease of use, fee structure (trading commissions and custody fees), and whether the specific ETFs you've identified are actually available on the platform. This framework doesn't recommend specific brokers — instead, apply those criteria yourself. Availability varies by country and platform, so confirm your target ETFs exist there before committing.
// Troubleshooting
My ETF dropped 30% — should I sell?
If you have a long time horizon and the ETF still matches your goals and diversification, a temporary 30% drop is normal market volatility, not a reason to sell. Selling locks in the loss. This framework is built for long-term investing precisely because volatility is tolerable over long horizons. Selling only becomes damaging if you're forced to at a bad time — which is why short-term money shouldn't be in ETFs.
I already own a broad market ETF — can I add a sector ETF?
First check your broad ETF's fact sheet, since it likely already holds that sector's companies. Quantify the existing weighting. Only add a sector ETF if you deliberately want to overweight beyond the index — a higher-conviction, higher-risk move that violates the diversification principle. If you proceed, size it as a small satellite allocation, not a core holding, and verify its expense ratio.
I found two similar ETFs — how do I choose between them?
Compare their expense ratios first, then their fact sheets for holdings, sector, and geographic breakdown, then their share class (accumulating vs distributing) against your tax situation. If they track the same index with similar holdings, the lower-cost option usually wins. Don't decide based on recent returns — near-identical index trackers will converge over time.
What if the ETF I want isn't available on my brokerage?
Look for an equivalent ETF that tracks the same or a very similar index and is available on your platform — for example a different provider's S&P 500 tracker. Compare its expense ratio and share class to your original choice. If nothing suitable exists, consider whether another brokerage with the right access and low fees is worth switching to.
// Comparisons
How do passive ETFs compare to actively managed ETFs?
Passive ETFs track an index at low cost (0.03%–0.3%) with no reliance on a manager's skill and historically competitive returns. Active ETFs are run by managers trying to beat the market, but charge 0.5%–1%+ with no guarantee of outperformance. For most beginners, passive is the default; consider active only with a specific, researched reason and comfort with higher fees.
How do ETFs compare to buying individual stocks?
ETFs give you instant broad exposure to many companies in one trade, drastically reducing single-company risk, while individual stocks concentrate your outcome on a few companies you must research and monitor. For beginners pursuing a long-term passive strategy, ETFs are simpler, more diversified, and less prone to costly stock-picking mistakes than assembling a portfolio of individual shares.
How does this framework compare to a generic 'just buy an index fund' tip?
Generic advice tells you what to buy but not how to decide or what to check. This framework adds structure: it matches your goal, horizon, risk, and country to specific exposure types, forces an expense-ratio and fact-sheet review, checks for index overlap and diversification gaps, and screens against the four common mistakes — turning a one-line tip into a repeatable decision process.
Are ETFs or mutual funds better for a beginner?
Passive ETFs are generally more accessible and lower-cost for beginners: they trade on an exchange like a stock, often carry lower expense ratios, and are straightforward to buy through any brokerage. Mutual funds can carry higher fees and less trading flexibility. This framework focuses on passive index-tracking ETFs specifically because of their low cost and simplicity for long-term investors.
// Advanced
How should I size an emerging markets allocation in my portfolio?
Emerging market ETFs offer higher growth potential but higher volatility, so they suit longer horizons and higher risk tolerance. Treat them as a smaller allocation alongside a core US or international position rather than a foundation. Size them according to how comfortable you are with volatility — the longer your horizon, the more room you have to ride out the swings.
Does the accumulating vs distributing choice change my long-term returns?
Yes, mainly through taxes and compounding. Accumulating ETFs reinvest dividends automatically and, in jurisdictions where dividends are taxed only on sale, defer that tax drag — letting more money compound over decades. Distributing ETFs give you cash but may trigger tax on receipt. Over long horizons, the tax treatment difference can meaningfully affect final returns, so match the choice to your country.
How do I use the four common mistakes checklist before finalising a purchase?
Before buying, confirm: (1) you're not chasing past performance, (2) you've checked and understood the expense ratio, (3) the portfolio is sufficiently diversified across regions and sectors, and (4) you actually understand what's inside each ETF via its fact sheet. If any answer is unsatisfactory, loop back to the relevant step before committing money.
When does adding another ETF stop improving diversification?
Once your ETFs cover multiple regions and company sizes without significant holdings overlap, adding more funds mainly increases complexity, not diversification. If a new ETF largely duplicates what you already hold — like a US ETF on top of a world ETF that's already 70% US — you're concentrating, not diversifying. Check fact sheets to confirm each addition brings genuinely new exposure.
