FAQ: best small-cap and micro-cap stock newsletters

What is a small-cap or micro-cap stock?

Definitions vary by publisher. Small caps are smaller public companies; micro caps and nano caps are smaller still. Stansberry's Ultimate Upside, for example, says it buys U.S. stocks under $1 billion in market cap.

Why do small-cap newsletters exist?

Many small companies get little or no analyst coverage. Undervalued and Undercovered says most of the companies it covers have zero analyst coverage, and Dirtcheapstocks says analysts don't cover the companies it writes about.

Are micro caps riskier?

They are often thinly traded, so prices can swing more and be easier to move. Read our small-cap newsletter guide and check who pays the writer.

Is this list a ranking?

No. Our own newsletter is listed first where it qualifies; the rest are in a fixed editorial order. Featured spots are paid and labeled Sponsored.
