Understanding Price-to-Earnings Ratios
Learn how to interpret P/E ratios when screening stocks. This metric helps identify whether a company is overvalued or undervalued relative to its earnings.
A step-by-step approach to identifying companies with consistent revenue expansion. Covers year-over-year analysis and growth trend interpretation.
When you're screening stocks, revenue growth tells you something fundamental: is the company actually selling more? It's not fancy or complicated. It's real. A company that can't grow revenue won't grow earnings, and that's where the money comes from.
We're going to walk you through exactly how to find these companies. You'll learn what numbers to look at, how to compare them year-over-year, and what growth rates actually matter. This isn't about chasing triple-digit growth — it's about finding consistent, believable expansion that screeners often miss.
Year-over-year revenue growth is your starting point. It's straightforward: compare this year's revenue to last year's, calculate the percentage change, and you've got your baseline growth rate.
Year-over-year (YoY) growth compares a company's revenue in one period to the same period a year earlier. It's the most reliable way to spot seasonal noise. If a retailer's Q4 revenue jumps 40%, you need to know if that's because of holiday sales or genuine expansion.
The calculation is simple: (Current Year Revenue - Prior Year Revenue) / Prior Year Revenue 100. Most financial sites show this already calculated. You're looking for consistency here. A company that grows 15% one year, then 8%, then 22% is telling you something different than one that grows 15% every single year.
When you're building a screening filter, we'd suggest looking for companies with at least 8-12% YoY growth over the last three years. That's not spectacular growth, but it's real. It's sustainable. And it eliminates the one-hit wonders.
This guide is informational and educational. Revenue growth analysis is one tool among many for understanding companies. Individual circumstances vary. Past growth doesn't guarantee future results. Always conduct your own research and consider consulting with financial professionals before making decisions.
Don't just look at last year's growth. You need to see the pattern. A company that grew 5% last year after growing 25% the year before is showing deceleration — and that matters. Three years of data gives you enough information to spot trends without being too far in the past to be relevant.
Pull the last three years of revenue. Calculate YoY growth for each period. Then ask yourself: Is this accelerating, steady, or declining? A company showing 10%, 12%, 15% growth over three years is accelerating. That's interesting. One showing 20%, 15%, 10% is decelerating. That's a warning sign — even though the latest number looks fine in isolation.
You'll also spot one-time jumps. If a company acquired another business, revenue might spike artificially. That's organic growth mixed with inorganic growth, and you need to know which is which. Most financial reports break this out, but you've got to look for it.
Growth benchmarks vary wildly by industry. A software company growing 15% might be declining. A utilities company growing 5% might be outperforming. You need context. Technology and healthcare typically show higher growth rates. Consumer staples and utilities show lower rates. That's just how these industries work.
When you're screening, compare companies within their own sector. A 10% growth rate for a bank is solid. A 10% growth rate for a biotech company is lagging. Don't mix them in the same filter unless you've got a good reason. Most screening tools let you filter by industry, so use that feature. It'll make your results much cleaner.
You'll also notice that mature industries show lower growth and younger industries show higher growth. That's expected. What you're looking for is companies growing faster than their peers. If the average software company grows 20% and you find one growing 35%, that's worth investigating. That's relative strength.
Here's the practical process. Don't overthink it. You're looking for companies that can prove they're expanding their top line consistently.
Use financial websites that show historical revenue. Yahoo Finance, Seeking Alpha, or company investor relations pages all work. You need at least three years of annual revenue data. Make sure you're looking at total revenue, not adjusted figures.
For each year, calculate (Current Year - Prior Year) / Prior Year. You'll get three growth rates. Document them. You're building a simple spreadsheet. This takes five minutes per company.
Are the three growth rates similar? Within a few percentage points is good. Big swings (25% one year, 5% the next) suggest volatility. You're looking for companies showing stable, predictable expansion.
Decide what growth rate matters for your screening. 10%? 15%? This depends on your sector and your goals. Be consistent. If you're screening tech stocks, 15% minimum might make sense. For industrial stocks, 8% might be your bar.
Revenue growth is important, but it's not the whole story. A company can grow revenue and still lose money. Growth from price increases isn't the same as growth from selling more units. You need to know the difference. If a company raised prices 15% and sold the same volume, that's 15% revenue growth — but it's not the same as selling 15% more stuff.
Organic versus inorganic matters too. If growth comes from acquisitions, that's different from organic expansion. Companies can buy growth. You want to see evidence they can generate it themselves. Most financial statements separate these, but you've got to look.
Don't stop at revenue. Use this as a screening tool to narrow your list. Then look at profitability, cash flow, and debt. Revenue growth gets you in the door. The other metrics determine whether it's worth walking through.
Revenue growth screening is straightforward. You're looking at historical data, spotting patterns, and identifying companies that can expand their top line consistently. It's not glamorous, but it works. Companies that grow revenue faster than their peers tend to be stronger businesses.
Start with the basics. Pull three years of revenue data. Calculate growth rates. Compare to sector peers. Set your minimum threshold. Then use that to build your initial screen. From there, dig deeper into profitability and cash flow. You've got a framework. Now it's just execution.
The best part? This works for any investor level. Beginners get a concrete metric to analyze. Experienced screeners can layer this into more complex models. Revenue growth screening scales with your sophistication. Start simple. Build from there.
