How do I compare two stocks?

Published October 31, 2026 · by Troels Højbjerg, Founder

Three numbers are enough to start: price, quality and trend

Comparing two stocks gets messy fast if you look at twenty figures. I use three scores from 0 to 100, and every stock page on WallStreetBuys shows them. A score is a ranking, not a percentage: 80 means the stock is ahead of 80% of all the stocks in our database on that measure.

Value says how cheap the stock is for its earnings, sales and book value. Quality measures how sound the business is: what it earns on what it owns, how much of its sales is left as profit, and a nine-point health check of its accounts. Momentum says where the share price sits against its own 20-, 50- and 200-day averages and how close it is to its high for the year.

The stock with the better quality score fell less in 68 of 100 pairs

To see whether the scores help when you have to choose, I took every pair of two US stocks on the same day and looked at the ones where the scores were far apart. Then I checked which of the two had the smaller drop along the way over the next three months:

Source: own calculation on 188 of the US stocks covered by WallStreetBuys. A start on the first weekday of each month from July 2025 to August 2026, then 63 weekdays ahead. Drop = the lowest close along the way compared with the start. Closing prices from our price database. Periods with an unadjusted stock split are left out.

The bigger the gap, the clearer the result. Momentum separated the two stocks less well than quality and value.

The scores say which stock tends to fall less, not which goes up more

This is a measure of calm, not of return. I do not claim that the stock with the better score made more money, and 14 months is too short to say so.

Roughly three times in ten, the lower-quality stock still held up better. A good company can also be a poor stock for a while, for example if the price has run far ahead of the earnings. That is why I look at the value score next to the quality score.

How to put two stocks side by side for free

Open the compare page and type in two tickers, for example aapl.us and msft.us. You get the scores, the signal and the distance to the analysts' price target for both, next to each other. It costs nothing and needs no sign-up.

The company's own annual and quarterly reports are free on the SEC's EDGAR database. They are the source when you want to check a figure yourself.

What WallStreetBuys cannot do

There is no screener where you set your own filters. Instead there are ready-made lists such as buy signals and best stocks. There is no portfolio tracker, no alerts and no advice.

The scores are not written by AI. Every stock is scored by the same fixed rules, from its reported numbers and its share price, after each trading day.

What the numbers do not tell you

Conclusion

To compare two stocks, put the same few numbers side by side: price for the earnings, quality of the business and the trend in the share price. In my data on 188 US stocks since July 2025, the stock with the clearly better quality score had the smaller drop over three months in 68% of pairs, and 72% when the gap was 50 points or more. The value score did slightly better, at 70% and 74%. Momentum was weaker, at 61%. None of this says which stock goes up more, and in about three pairs out of ten the weaker stock held up better. With only 14 months of data, I would treat it as a direction, not a rule.

One thing to check: take the two stocks you are choosing between and look at the gap in their quality score. If it is under 30 points, that score will not settle the choice for you.

You can see the scores for both stocks next to each other, free and without sign-up, on the compare page.

Frequently asked questions

How do I compare two stocks?

Put the same few numbers side by side: what the stock costs for its earnings, how sound the business is, and how the share price has moved. I tested the first two on 188 US stocks since July 2025. When two stocks were 30 points or more apart on quality, the higher-quality one had the smaller drop over the next three months in 68% of pairs. On value it was 70%. A coin flip would give 50%. The scores did not tell you which stock would go up more, only which one tended to fall less.

Where can I analyze stocks for free?

On WallStreetBuys every one of the 200 US stocks we cover has a free page with no sign-up: the analysts' price target, a value, quality and momentum score from 0 to 100, a technical signal and red flags, recalculated after each trading day. The company's own reports are free on the SEC's EDGAR database, and most brokers show prices and key figures to their customers at no extra cost.

What is the best free stock screener?

I have not tested the free screeners, so I cannot rank them. WallStreetBuys does not have a screener where you set your own filters. It has ready-made free lists instead: stocks with a buy signal, the highest scores, dividend stocks, insider buying and the most shorted stocks.

What is the best AI tool for stock analysis?

I cannot name one, because I have not tested them against each other. A general chatbot can get numbers wrong, so check any figure it gives you against the company's report or a stock page. The scores on WallStreetBuys are not written by AI. They are calculated by the same fixed rules for every stock, from its reported numbers and its share price.

What is the best stock portfolio tracker?

WallStreetBuys has no portfolio tracker, so I am the wrong person to ask. Your broker shows your holdings and your result. What you can do here is look up each stock you own on its free page and see its scores and signal.

What is the best stock analysis platform for individual investors?

It depends on what you want it to do. A broker is for buying and selling, a charting tool is for drawing your own analysis, and a screener is for filtering. WallStreetBuys is for a quick, free answer on one US stock: the same scores and signal for every stock, without sign-up. It does not give advice, and it has no alerts or portfolio.
