Best ETF & Mutual Fund Research Tools (2026)

Last verified: August 23, 2026 · Disclosure: Stock Rover is our product; ranked first with its weakness stated, alternatives recommended for real reasons.

Most of America’s investing money sits in funds, yet fund research is where the tools industry gates hardest: Koyfin locks funds behind $209+/mo Advisor tiers, TIKR behind its $119.95 Ultimate, and Morningstar charges $249/yr with little screening attached. Here’s what actually works, at what price.

What fund research must answer

1. Stock Rover Best research + portfolio integration (our product)

Ultimate, $79/mo billed annually (funds tier) · 14-day card-free trial. Research reports on 7,400 ETFs and 20,000 mutual funds (ratings, fees, tax efficiency, Investor Warnings) integrated with your linked accounts: the Portfolio Performance Report unpacks every fund into true per-company exposure and prices your fund fees in dollars, next to category averages and their 10-year compounding cost.

Stock Rover fund fee audit: weighted expense ratio, dollars per year, ten-year cost, expense ratio vs category average

The fee audit that routinely pays for the subscription.

Where it falls short: Fund reports require the $79 Ultimate tier; the $29 and $49 tiers research stocks and track funds but don’t include the full fund library. Data-generated reports, no human analyst prose.

2. Morningstar Investor The ratings authority

$249/yr. Star and medalist ratings plus human analyst research: the language the entire fund industry speaks. For fund selection by reputation and rigor, still the reference.

Where it falls short: Screening is basic, the price buys ratings more than tools, and portfolio analytics trail its own X-ray heritage.

3. VettaFi / ETF Database Best free ETF lookup

Free (ad-supported). Quick ETF profiles, holdings, flows and comparisons: the fastest zero-dollar answer to “what’s in this ETF?”

Where it falls short: ETFs only, surface depth, and no connection to your accounts.

4. Koyfin (Advisor tiers) For professionals

From $209/mo. Elegant fund analytics inside the Koyfin terminal experience, if a practice is paying.

Where it falls short: That price for fund data is exactly why individual investors look elsewhere; retail tiers exclude it.

5. Your broker’s screener (Fidelity, Schwab) Best free fallback

Free with an account. Solid fund screeners and Morningstar-lite data pages; decent for occasional lookups.

Where it falls short: Walled to their fund lists and interfaces; nothing follows your accounts elsewhere, and depth stops early.

The 401(k) test

Whatever tool you pick, run one exercise this week: list your retirement plan’s funds, their expense ratios in dollars, and each one’s 10-year cost vs the category’s cheapest equivalent. In Stock Rover that’s automatic in the report’s “What you pay” section; done by hand it’s an hour that often finds a four-figure leak.

Audit your funds free

Link accounts or import holdings; the fee audit and look-through run in the 14-day trial.
