US ETF deep dives — holdings, fees, sectors, and portfolio role for 101 funds

An ETF ticker does not tell you exactly what you are buying. SPY and VOO both track the S&P 500 but differ in fees, legal structure, and trading characteristics. SCHD and VYM both carry a dividend label but use different selection rules. ARKK and ARKB look similar as tickers but represent entirely different exposures. A useful deep dive makes those distinctions visible without treating the fund name as a complete investment thesis.

Start with VOO, SPY, or QQQ to see the format.

1. ETF facts — issuer, exchange, launch date, expense ratio, assets, and stated strategy.
2. Top holdings and concentration — the largest positions, top-10 weight, and whether a small group drives the fund.
3. Sector, country, or asset exposure — the actual portfolio mix behind the marketing label.
4. Index or strategy — what the fund follows, how the exposure is selected, and which methodology changes matter.
5. Portfolio role — whether the fund is closer to a core holding, diversifier, income tool, hedge, or concentrated satellite.
6. Investor checklist — fees, overlap, liquidity, concentration, macro sensitivity, and the evidence to monitor after purchase.

SnowballHare currently publishes 101 ETF deep dives. The underlying generated dataset uses 37 detailed categories across 4 asset classes, including broad equity, growth and value, international, sector, fixed-income, commodity, currency, and digital-asset exposures. This source-derived classification is more granular than a short editorial menu.

Each deep dive has one canonical URL based on the ticker or descriptive slug. The listing below remains paginated in groups of 24, ordered so widely followed funds appear early while the complete set remains accessible through page links.

• Issuer fund pages and prospectuses — official strategy, fees, fund facts, and methodology documents.
• Public holdings disclosures — portfolio snapshots and concentration data where available.
• SEC EDGAR — regulatory fund reports and source documents used for verification.
• Market-data services — price history and reference fields used to add context, with dates shown on the page.

Holdings and fund facts do not all update on the same schedule. Some issuers publish daily holdings, while other products report monthly or quarterly. SnowballHare refreshes supported source snapshots through scheduled data builds and displays the relevant as-of date. See the research methodology for validation rules.
