Small-Cap vs Micro-Cap Stock Newsletters: What's the Difference? (2026)

In short: Micro caps are tiny companies (often under $250-300 million, per Investor.gov); small caps are a bit bigger. We list 15 newsletters that cover them, with official-page prices.

Direct answer: Both cover smaller public companies. Micro caps are the tiniest: the SEC's Investor.gov says companies worth less than $250 or $300 million are often called microcap stocks, and under $50 million, nanocap stocks. Small caps are larger, but every publisher draws the line differently. We list 15 newsletters that cover this part of the market. Not investment advice.

Questions

What is the difference between a small cap and a micro cap?

It is about company size (market capitalization). The SEC's Investor.gov says companies worth less than $250 or $300 million are often called microcap stocks, and those under $50 million are sometimes called nanocap stocks. Small caps are bigger than that, but definitions vary by publisher.

Why do newsletters focus on micro caps?

Many tiny companies have little or no analyst coverage, and big funds often can't buy them. Several newsletters in our directory say that is exactly why they look there.

Are micro-cap stocks risky?

Yes, often more than large stocks. Investor.gov notes that microcap stocks are sometimes called penny stocks, and they are a common target for promotion schemes. Check who pays the writer and read the disclosures.

How much do small-cap newsletters cost?

In our directory, the lowest annual price among paid small-cap newsletters is $255 a year (ShareIdeas.uk (Small/Mid Caps with Paul Scott)) and the highest is $800 a year (Dirtcheapstocks), per their official pages.
