What is a “quality company”?
Picture two shops on your street. The first earns a steady profit every year, calmly pays down its debt, and keeps its customers. The second has one big year, then nothing, and borrows to survive. The first is “quality”: it turns its business into cash in a durable way.
A stock is a slice of the company. Buying a quality stock means becoming a co-owner of a good shop. The rest, the price going up or down each day, is just noise around that reality.
Why look at quality before price?
Many beginners first hunt for “the cheap stock”. That’s a trap. A bad company can stay cheap for a very long time… because it isn’t worth more.
That’s our core rule: we only care about a stock’s price after confirming the company is solid. Quality comes first, price second.
What are the 5 things to look at?
- What it earns on the money invested. For every dollar tied up in the business (factories, inventory, software), how much does the company earn? A company that earns a lot with little doesn’t have to fight just to survive.
- The cash it generates. How much of its sales turns into money actually available, once its expenses and investments are paid? A profit can be debated; cash is a fact.
- The growth of its sales. Is its revenue progressing at a healthy pace over five years?
- Margins that improve. As the business grows, does the company keep a bigger share of every dollar of sales?
- Controlled debt. How many years of earnings would it take to repay its debt? A company that’s too indebted wobbles at the first setback.
Our Q-Score (soundness score, from 0 to 100) combines these five pillars into a single number. The higher it is, the more solid the company. Until a stock has a high enough Q-Score, we don’t even look at its price.
The question no score settles
A score measures what’s quantifiable: what the company earns, the cash it generates, its growth, its margins, its debt. But quality has a part no number fully captures: what stops a competitor from taking this company’s place in ten years?
A brand customers love, a cost no one can beat, a habit that’s hard to quit: that’s a durable advantage (often called a “moat”, like the water around a castle). The Q-Score tells you the company is solid today; whether that advantage holds tomorrow is your judgment, not a number’s. We shed light, you decide.
What are the beginner traps?
- Growth ≠ quality. A fast-growing company isn’t necessarily solid: it may be burning cash to grow. Check whether growth comes with real profits.
- Hype ≠ strength. A stock everyone talks about isn’t a good stock by default. Media noise says nothing about the company’s real health.
- “Cheap” can be a trap. A stock that has dropped a lot isn’t a bargain if the company is deteriorating. Check the quality before calling it an opportunity.
In practice
Rather than analyzing hundreds of companies by hand, you can start from a list already sorted by quality. Every night, we screen S&P 500 and CAC 40 stocks and compute their Q-Score. The best-rated rise to the top: a way to start your research with solid companies, not bets.
