## GuruFocus

**Value-investing research platform with a deep screener, guru 13F tracking and 30 years of financials; priced per market region.**

**Best for:** Value investors who research deeply, want guru tracking and long financial history, and mostly work one market region.

Strengths:
- Thirty years of financial history standard (forty marketed), with delisted stocks on the top tier
- Screener combines fundamental, technical and custom-expression filters with real backtesting to 2006
- Guru and insider tracking at scale: 13F portfolios of 8,000+ institutions, funds and politician trades
- Documented valuation stack: GF Value, GF Score, two DCF variants and the Graham Number

Trade-offs:
- Every market region is a separate subscription ($369–549 per year each) — multi-market investors pay multiples
- The free account is a research teaser: screener results are masked beyond the first rows
- Rigid billing (non-refundable, cancellation via support ticket) and weak charting — a review quoted on their own pricing page recommends charting elsewhere

## Zacks

**US research service built around the Zacks Rank; genuine free tier, a large preset-screen library and a 125-field custom screener.**

**Best for:** US-focused investors who want an opinionated, estimate-driven rating system with a usable free tier — not a technical scanning workstation.

Strengths:
- Zacks Rank has run continuously since 1988 on a documented estimate-revision method — and covers mutual funds and ETFs too
- Deep genuinely free tier: rank and Style Scores, portfolio tracker with daily email alerts, basic screens
- Large curated library: 45+ premium screens in 9 strategy categories plus 39 thematic screens
- Unmatched earnings-estimate depth: revisions, surprises and the Earnings ESP filter

Trade-offs:
- Screens US exchanges only — no foreign exchange is searchable, international exposure is ADRs
- Technical criteria are minimal: price action and volume, no RSI or moving averages
- Custom formulas and backtesting require Research Wizard, sold separately on top of Premium — and renewal prices of the higher bundles are not public
