WallStreetZen
A to F ratings and DCF fair values for US stocks, plus analyst accuracy rankings. Free for life, Premium $19.50 a month.
Part-time investors in US stocks who want a verdict and a number are WallStreetZen's audience. Zen Ratings grade about 4,600 stocks from A to F using 115 factors, with seven component grades underneath, and each stock also gets its own DCF fair value, kept apart from analyst price targets. The site ranks analysts by how accurate their past calls were, and you can follow up to 200 of them. The Basic plan is free for life, with the letter grade, a screener without export and ads. Premium costs $19.50 a month billed yearly, after a $1 trial and with a 90-day money-back guarantee, and add-on newsletters reach $997 a year. Its marketing mentions thousands more stocks globally, but the screener's exchange filter lists four US venues. Its own help centre confirms there's no app.

Part-time US stock investors who want a rating and a fair value without paying much. Skip it if you hold ETFs or non-US stocks: it screens neither.

WallStreetZen vs PortfolioGlance
WallStreetZen grades US stocks and computes fair values, and we do neither. It has no portfolio product beyond watchlists, so cost basis, dividend income and goals aren't there to compare. For a European investor it covers the US slice at most. The whole portfolio, across markets and asset classes, is what we track.
