Why Use an Investment Newsletter Directory?
The investment newsletter landscape has exploded. Substack alone hosts thousands of finance writers, ranging from professional fund managers sharing annotated thoughts to independent analysts producing institutional-quality deep dives. The problem is discovery: how do you find the right analysts for your specific niche?
Substack finance leaderboards surface the newsletters with the largest audiences — not necessarily the best research. Generic “Top 10 newsletters” blog posts recommend the same handful of well-known names, often because they have affiliate programs. Neither approach helps you find the analyst covering Swiss quality compounders, Japanese micro-caps, or Korean conglomerates.
RhinoInvestory solves this by indexing 800+ individual stock write-ups tied back to the newsletter authors who published them. When you filter by country or sector, you see the actual research — and the analysts behind it. It's a discovery layer built for investors who want to go deeper than the obvious names.
How to Build Your Investment Research Stack Using This Directory
- Start from your niche — Use the country or sector filters to find write-ups in your area of focus. Example: Information Technology stocks in Switzerland or micro-caps in Japan.
- Evaluate the research quality — Look for: depth of analysis, use of financial data, quality of valuation work, risk discussion, and writing clarity.
- Click through to the author page — Each author has a profile page listing all their published write-ups in the directory, so you can evaluate consistency.
- Subscribe to 5–10 newsletters — Add your shortlist to RSS, Substack, or email. Over 30–60 days, prune to the 3–5 that consistently add signal to your process.
- Use free tools alongside newsletters — RhinoInvestory also offers free DCF calculators, intrinsic value calculators, and other free investing tools to complement your newsletter research.

Investment Newsletter Directory — FAQ
What is an investment newsletter directory?
An investment newsletter directory is a curated, searchable index of stock research newsletters and investment publications. It helps investors discover new analysts, compare newsletter styles, and find research that matches their investment approach — by country, sector, market cap, or investment style. RhinoInvestory is one of the most complete investment newsletter directories available, covering 800+ stock write-ups from 200+ authors worldwide.
How is RhinoInvestory different from other newsletter directories?
Most newsletter directories list 10–20 well-known, high-audience newsletters — often based on affiliate deals. RhinoInvestory indexes 800+ individual stock write-ups tied back to the newsletter authors who published them. This means you can discover analysts by the specific stocks they cover, not just their brand name. You can filter by country (e.g., Japan, Germany, Switzerland), sector (e.g., Technology, Healthcare), or investment style (value, growth, dividend).
What types of investment newsletters are included in the directory?
The directory includes: value investing newsletters, growth stock newsletters, dividend and income newsletters, macro and global economics newsletters, small-cap and micro-cap newsletters, sector-specific newsletters (Technology, Healthcare, Energy, Consumer, Financial), country-specific newsletters (US, Europe, Japan, Canada, Korea, Emerging Markets), and hedge fund quarterly investor letters.
Are there free investment newsletters in the directory?
Yes. Many newsletters in the RhinoInvestory directory are completely free, especially independent analysts who publish on Substack or their own websites. Some offer a free tier with access to selected articles, with premium content behind a paid subscription. The newsletter listing pages indicate when a newsletter is free.
How do I find newsletters about stocks in a specific country?
Use the 'Browse by Country' section: navigate to rhinoinvestory.com/stock-analysis/country and select a country to see all curated stock write-ups from that market — along with links to the newsletter authors behind each article. This is particularly useful for discovering analysts who cover Japan, Germany, Switzerland, Canada, Korea, and other non-US markets.
How do I find newsletters focused on value investing?
Browse the Newsletters section and filter by category, or explore stock write-ups in the Stock Analysis directory — each article is labeled with the investment style and sector. Authors with a value investing approach typically cover FCF yield, DCF valuation, margin of safety, and competitive moats in their write-ups.
Can I submit my newsletter to the RhinoInvestory directory?
Yes. RhinoInvestory welcomes submissions from investment newsletter authors and independent analysts. The directory is designed to surface quality research from all corners of the global investment community — not just established names.
What is the difference between a stock newsletter and a hedge fund letter?
A stock newsletter is typically published by an independent analyst or small firm, covering stock ideas, company research, and investment strategies for retail investors. A hedge fund letter is a quarterly or annual investor communication from a professional fund manager (like Berkshire Hathaway or Pershing Square) explaining their portfolio decisions and investment thesis.
