Both are famous for their stock ratings – thousands of people across the world pay to have access to each of their “Strong Buy” stocks and which “Strong Sell” stocks to avoid.
Both use expert analysts’ research and analysis to derive information about investments. Their goal is to provide investors with tools to learn and build their own portfolios.
But they also have stock newsletters where they release their top rated stocks that they believe are most likely to outperform the market.
They are similar in many ways, but the main difference is their approach to researching and presenting stock data. This article should help you decide which service fits your investing style better – Seeking Alpha or Zacks?
Performance of Recent Stock Picks
For those of you who just want to know which of their stock picks are better, I will get right to the point. How do the Seeking Alpha stock picks compare to the Zacks stock picks?
I subscribe to over a dozen stock picking services, and here is my most recent analysis of how their picks have performed over the last 3 years. For Seeking Alpha, I subscribe to their Alpha Picks service; and for Zacks I subscribe to their 4 most popular subscriptions that are less than $500 a year.
These are ranked based on their performance versus the S&P500 for the last 3 years. Seeking Alpha’s Alpha Picks is by far the top performer.
As you can see, Alpha Picks is crushing all of the others based on their average gain versus the S&P500 over the last 3 years–beating the S&P by 47% across 64 stock picks.
A relatively new service called Moby Premium is coming in 2nd– see my Moby Stock Picks Review.
As to be expected, Motley Fool’s Stock Advisor is doing well and is in 3rd place with an average return of 43% and 78% accuracy rate.
Zacks Value Investor is doing well too, but they have not been making very many picks over the last few years. The Motley Fool’s Rule Breakers stock picks-now known as Epic are doing quite well, as are Zacks Value Investor has only released 3 new picks in 2025, but they released 9 new picks in 2024, and their 2023 picks did so well they are carrying the average. Motley Fool’s Canada Stock Advisor is doing well and Zacks Top 10 is always doing OK.

How They Each Started
About Zacks
Zacks was started by Len Zacks in 1978, a Ph.D. from MIT.
Len was obsessed with analyzing Wall Street Analysts and wanted to build his own team of in-house analysts.
His vision was to create a team who could rate stocks, then provide productized ranks and lists for investors to analyze and build their portfolios.
Zacks believes that earnings estimate revisions are the most powerful factor to drive stock prices.
Basically, when financial analysts change how much a company will earn in a quarter, that can change stock prices more than anything else.
About Seeking Alpha
Seeking Alpha was started in 2004 by financial analyst David Jackson. The original plan was to create a research platform where passionate investors can share their own stock analysis with a community. The word “alpha” in stock market lingo is the percentage that your portfolio beats the market.
A big component of Seeking Alpha is this unique idea of crowdsourcing investing. Sharing knowledge with a community and all supplying, refining research, insights, and opinions.
Instead of having its own analysts, Seeking Alpha uses Wall Street analysts, individual investors, fund managers, and other reputable market watchers.
They do have in-house editors who cover current market news and review articles submitted to their forum.
Their Stock Ratings
The main reason to use either of these services is to research your own stock ideas and analyze your own portfolio. But they both have recently started stock newsletter services–more on this at the end.
Each of these platforms provides a list of stocks that are rated to get an idea of what to research. All these lists and ratings are done by respected analysts or quantitative factors.
Zacks Stock Rank
Zacks has a very straightforward rating system. In the areas of value, growth, and momentum, stocks are given a ranking of A through F. Based on the grade received in each category, stocks are then assigned a rank from 1 (Strong Buy) to 5 (Strong Sell).
The Zacks #1 list shows you the top 5% of stocks with the most potential. There are stock screens that allow you to pick stocks based on your investing strategy.
Zacks uses quantitative analysis to rate and rank stocks. This algorithm gives Zacks objective information to find the best stocks.
Zacks’ rankings have done very well against the S&P 500 as you can see in this chart:
Over the past 34 years, stocks that Zacks rank as a “#1 Strong Buy” have outperformed the S&P 500 by an average of 13.8% each year. Zacks has proven that its system works and why so many investors use its analysis.
See the Zacks #1 Rank Strong Buys
Zacks also provides rankings for ETFs, mutual funds, and other equities.
Seeking Alpha Quant Rating
Seeking Alpha has a top-rated stocks list as well, compiling of 50-75 stocks that earn Strong Buy scores. Scores are broken up and determined by Seeking Alpha contributors, Wall Street analysts, and Seeking Alpha’s quantitative algorithm. Any stock with a rating above a 4.5 is rated a Very Bullish buy. (If you want to do a deep, deep, deep dive into this read our Seeking Alpha Quant Rating Review).
Beside the analyst’s score, each stock is also given a letter grade for valuation, growth, profitability, and momentum. These ratings provide investors with a very easy way to get stock ideas.
Seeking Alpha has also done extremely well compared to the S&P 500 since 2010. Seeking Alpha’s “Strong Buy” rated stocks based on Quant Performance, are crushing the market as you can see bellow.
That’s 7x the average return of the S&P 500!!
Their quantitative analysis is slightly more successful compared to the market than Zacks.
Also of huge importance is an academic study that was released in April, 2024 by professors at the University of Kentucky that confirmed Seeking Alpha’s Quant Rating did provide relatively accurate predictions of future price movements. This is huge as it is the first time we have seen an academic study support the value of a certain stock service.
Their Stock Research
Seeking Alpha and Zacks provide stock research that is detailed and reputable.
Zacks is the better option if you want a traditional stock research report – a single report that’s relatively easy to read and presents a professional analyst’s view of a company they’ve been following for many years.
Each report contains a deep dive into the company and a look at its fundamentals and growth potential. They offer an in-depth report for every stock they cover.
Zacks also focuses a lot of Wall Street earnings forecasts, how the company actually do versus their forecasts, and then they place a lot of weight on forecasts CHANGES. If suddenly several analysts are improving their forecasts and raising a stock from BUY to STRONG BUY, or raising their estimated income from $1.25 a share to $1.35 a share, Zacks reports on this.
Another major feature of Zacks is their stock screener. It allows investors to filter and search for companies based on the return of investment, price changes, earnings per share, or your own investment style.
Zacks also offers interactive charts that show a stock’s reaction to earning reports and other fundamental data.
Seeking Alpha is the better platform if you want a complete quantitative analysis of diversity of viewpoints, analysis methods, and opinions.
Reading through several analysis articles takes more time than reading a single research report, but advanced investors can dive deeper into both the bull and bear cases for a stock.
This gives investors more tools to decide their strategy and grow their portfolio.
Seeking Alpha provides a stock screener that enables you to sort and search by financial ratios, analyst ratings, profitability, and many other fundamental and technical configurations.
This is my preferred method for researching stocks, which is why I’m a member of Seeking Alpha Premium.
Other Features
Both have education centers
- Zacks offers videos and courses on investment strategies. Zacks also has a complete guide on understanding the power of earnings estimates.
- Seeking Alpha offers numerous articles about the world of investing, portfolio management, and their quant ratings. If you are not much of a reader, they have investing podcasts and videos as well.
Seeking Alpha has news, and editors report on live coverage. It is a nice feature to have updated news on the stock market world and research your next stock pick all in one place.
Zacks provides an earnings calendar. It tells you which companies are releasing their earnings that specific day and what time of day they come out – before the market opens or after it closes.
Once the earnings report is released, it compares Zacks’ estimate to the actual results and the price change.
Each platform has a portfolio tracker. At Zacks, you will see their rankings of all the equities currently held and receive daily email notifications on the performance of your portfolio.
Same thing for Seeking Alpha, up-to-date notifications of your portfolio’s health.

Seeking Alpha Alpha Picks stock recommendations: $499 per year. If you are looking for 2 stock picks a month that have Seeking Alpha’s highest Quant Rating that have been vetted by their team of CFAs, Alpha Picks is the best choice.
Notably, Seeking Alpha’s 2022 Alpha Picks are by far the best performers, easily beating the Motley Fool’s and Zacks various services.
Here’s all the data on their picks:
- They had 16 picks (6 in July and then 2 each month thereafter) in 2022
- They made 24 picks in 2023
- They released 21 picks in 2024.
- They have released 11 picks so far in 2025.
- Of these 60+ stock picks, THEY ARE DEFINITELY GENERATING ALPHA as they, on average, are beating the S&P 500 by an average of over 47%
- More importantly, of their picks that are at least 12 months old, they are beating the S&P 500 by 55%, with 76% stocks being profitable
- Alpha Picks Update as of June 29, 2025: Since its launch in July, 2022, the 76 Alpha picks from 2022 thru 2024 are up an average of 63% and are easily beating the S&P500's return of 23% by 40%. But most impressively, their picks that are at least 12 months old are up 88% vs 30% for 58% ALPHA and 77% of those picks are profitable. Yes, these picks are tripling the SPY. Their November picks are already up 88% and 85%, June 2024 pick of SFM is already up 105%, their April, 2024 pick EAT is up 251%, their March pick RCL is up 140%. Oh yea, their November 2023 pick of APP is up 686%! See our full Seeking Alpha Picks Review for further analysis.
- They have sold 31 positions; so they are pretty quick to dump non-performers. TravelCenters (TA) was acquired in February 2023 for a 56.8% gain after they picked it in August 2022; they sold CVX with a 1% profit, COP with a 30% profit, NUE with a 60% profit, and both LTHM and HLIT with 32% losses. The others that were sold were all +/- 8%.
- Since inception, 73% of the stock picks have been profitable.
MOST IMPORTANTLY, their stock picks are easily beating all of The Motley Fool’s and Zacks’ services over the same time period:
THAT is exactly what you want from Alpha Picks. The longer you hold a stock the better it performs.
Remember, to get these results, you should try to buy equal dollar amounts of all the Seeking Alpha Alpha Picks stocks as they are released. Based on what I have seen so far, I will be buying about $1,000 of each of their picks as they come out.
As I mentioned, I am also a subscriber to the Motley Fool’s Stock Advisor and Rule Breakers. Alpha Picks’ return is the clear winner over the same time period.

My Experience with Seeking Alpha and Zacks
Zacks
I like the lists they send via email, but don’t think I would ever browse the site.
The earnings calendar is helpful to keep up to date.
