Zen Ratings and WallStreetZen Review Including Premium Cost

WallStreetZen Premium is worth it for a US part-time investor who wants a short list of highly rated stocks and analyst calls filtered by track record, and who will act on that list for at least a few months. It costs $234 a year ($19.50 a month billed yearly) or $59 month to month, with a 14-day trial for $1 and a 90-day money-back guarantee. Treat the Zen Ratings returns with care: WallStreetZen's own performance page says they come from a backtest that ignores trading costs.

We read WallStreetZen's Zen Ratings page, its plans page (with the monthly and yearly toggles), its Performance page and its Terms of Service on October 9, 2026. Figures below are quoted from those pages unless we name another source or say the arithmetic is ours.

WallStreetZen at a glance

Is WallStreetZen worth it?

WallStreetZen is worth paying for if your problem is too many stocks and too little time. The free plan already shows the letter grade on every quote page, so Premium is really buying three things: the full list of A-rated stocks, alerts when a rating changes, and unlimited access to the analysts it ranks. At $234 a year that is about 64 cents a day by our arithmetic, in line with other research subscriptions.

It is not worth it if you want proof that following the grades will make you money. The +28.50% figure is a model result with no trading costs, and the plans page that repeats it also runs testimonials and hand-picked winners. A rating is a starting point for research, which is how the site itself frames it when it tells you to "remain realistic with your expectations."

How much does WallStreetZen Premium cost?

Premium costs $59 a month on monthly billing or $234 a year on yearly billing, which the plans page shows as $19.50 a month and "only $4.50 / week". The yearly plan is $474 cheaper over twelve months, 67% off the monthly rate by our arithmetic, which is where the page's "Save 67%" label comes from. There is one paid research plan. WallStreetZen also sells separate services, Zen Investor, Zen Options and Zen Strategies, whose prices are not on the plans page and which this review does not cover.

Two terms decide what you actually pay. The subscription "will automatically renew for the annual or other subscription period you originally signed up for", and WallStreetZen says it will email you before a trial or promotional period ends. Cancel in the billing portal under Account Settings, or by email. Put the renewal date in your calendar on the day you subscribe. If you will pay for it from a business account, that renewal is also a recurring invoice someone has to file.

What do you get with WallStreetZen Premium vs free?

The free plan is more useful than most. Every quote page shows the overall Zen Rating and the seven component grades, so you can check any stock you already own. What the free plan withholds is discovery: the ranked list of A-rated stocks, the rating changes, and most of the analyst data.

How are Zen Ratings calculated?

Zen Ratings score more than 4,600 US stocks every market day on 115 factors and turn the result into a percentile, then a letter grade. WallStreetZen says the factors fall into seven groups: Financials (26), Growth (22), Momentum (22), Value (21), Sentiment (14), Safety (6) and one Artificial Intelligence factor, a neural network "trained on over 20 years of historical fundamental and technical data". The last three factors measure company size and, in its words, "skew the model slightly towards small cap stocks." The model was built with "a leading data science firm" that the page does not name.

The grades line up in order, which is what a working ranking should show. The plans page says that only 231 of more than 5,300 US stocks were A-rated when we read it, and that $10,000 in A-rated stocks in 2006 "would be worth $1,512,952 today". That is close to what +28.50% compounded for 20 years gives, about $1.51 million by our arithmetic.

Are Zen Ratings accurate?

The ranking may well be real. The size of the return is the part to discount, and WallStreetZen's own Performance page tells you why. Read it before you pay, because it describes a test you could not have traded:

• It is a backtest. The numbers "are based on a backtest study" and "are entirely the product of computer models", not a record of live money.
• No trading costs. "We do not take trading costs into account." The A list is rebuilt every month from about 5% of the market, so turnover is high, and small, thinly traded stocks cost the most to trade.
• A price you could not get. Trades are "priced at the average of the high and low for that day". A real order fills at the price when you place it, not at the day's midpoint.
• A small-cap tilt. The model deliberately leans toward small companies, exactly where spreads and slippage are widest.
• Training and test overlap. The AI factor was trained on more than 20 years of data and the record covers 20 years. WallStreetZen says it uses cross-validation, but the page does not say whether the 2006 to 2025 returns are out of sample.
• No weighting or holding rules. The page does not say how the A bucket is weighted, and nobody holds 231 stocks rebalanced monthly in a personal account.

None of this makes the grades useless. It means the honest claim is "A-rated stocks have ranked well in a model", not "you will earn 28% a year". TipRanks' Smart Score carries the same kind of caveat, and our TipRanks review quotes its disclaimer.

Is WallStreetZen legit?

Yes, WallStreetZen is a real, established research site that bills through a mainstream card processor, offers a 90-day refund, and is open about its method on a public Performance page. It is not a broker or an adviser: its footer says it "does not provide financial advice and does not issue recommendations or offers to buy stock or sell any security." The plans page claims it is "Trusted by 310,587+ serious part-time investors"; that is its own figure, which we did not verify.

For a professional the licence matters more than the price. The Terms of Service grant use "for personal, non-commercial transitory viewing only" and bar using the materials "for any commercial purpose". We found no professional plan, so an adviser should get written permission before using the ratings in client work. How 25 other vendors treat professional users is on our non-professional subscriber page.

WallStreetZen vs TipRanks, Zacks and Danelfin

All four sell a stock score backed by a backtest. Prices for the other three are from our own source reads on the linked pages.

WallStreetZen has the longest written refund window on its standard plan of the four, which makes it the cheapest to try properly. Zacks Rank has the longest public history, and our Zacks Premium review covers it. If you would rather pick stocks from fundamentals you can read yourself, our Simply Wall St review covers the visual alternative.

How to check a Zen Rating idea before you rely on it

A grade tells you what to look at. It does not tell you when to sell, and the selling rule is where most of the result comes from. WallStreetZen's own suggested rule is to sell "when the rating drops to C or below", which you can only follow by checking the site every week.

Two practical steps help. First, keep a record of what you acted on. Premium sends rating changes and watchlist updates by email, so if you pull those alert emails into a spreadsheet as they arrive, you can compare each upgrade with what the stock did over the next six months, net of what you paid to trade it. Second, test the holding rule you would actually use on the stock you are considering. Type it in plain English into our trading strategy tester, for example "buy AAPL and sell when it closes below its 200-day moving average", and it runs on 20+ years of split- and dividend-adjusted daily data with a cost on every trade, then reports the drawdown and a plain verdict against buy and hold. For the company itself, the fundamental analysis tool lays out the numbers behind each verdict.

Our verdict on WallStreetZen

WallStreetZen is a well-made research site with a generous free plan and the most forgiving refund policy among the stock rating services we have reviewed. For a US part-time investor who wants a ranked shortlist, Premium at $234 a year is fair value, and the $1 trial plus 90 days to ask for your money back make it low risk. Skip the monthly plan: at $708 a year it costs three times as much for the same features. And read the +28.50% as what the Performance page says it is, a backtest with no trading costs at a price you could not have traded, then test your own buy and sell rule before you put money behind a grade.
