A cyclical stock usually looks cheapest right before it gets crushed. Bad luck has little to do with it. When earnings swing as hard as they do in steel, chemicals, memory chips or oil, the math more or less guarantees it.
Read stock graphs for these companies the way you’d read them for a steady consumer brand and you’ll end up buying near the top and selling near the bottom with impressive consistency. The shapes are different, and the rules change with them.
The Earnings Line Looks Like a Saw
On long-term stock graphs, a steady compounder’s earnings line climbs at a fairly even angle. An automaker or a chemical producer looks more like a saw blade. Big run-ups, sharp drops, sometimes straight into losses, then back up again.
That pattern comes from the business itself. Demand rises and falls with the broader economy, and costs don’t shrink nearly as fast as revenue does, so profits magnify every swing. A ten percent dip in sales can wipe out far more than ten percent of earnings.
The single most useful habit is looking at stock graphs that show earnings across at least two full cycles, ideally fifteen or twenty years of data. One cycle can fool you. Two or three show roughly where the peaks and troughs tend to land, which gives you some sense of what “normal” might mean for that particular company.
Why the P/E Gets It Backwards
This is where cyclicals mess with people.
At the top of a cycle, earnings are huge, so the P/E ratio looks low. Seven times earnings seems like a bargain. But those earnings are about as good as they’ll get, and the market knows it, which is exactly why it won’t pay more.
At the bottom, earnings collapse or go negative. The P/E balloons or stops meaning anything at all, and the stock looks absurdly expensive (or simply broken) right around the time it’s cheapest relative to what it can earn over a whole cycle.
Peter Lynch made this point decades ago in One Up on Wall Street, and it still trips people up. With cyclicals, a low P/E can be a warning and a high one can be an opening, close to the reverse of how most screens are built.
So on stock graphs of cyclical companies, I mostly ignore the current multiple and look at where earnings sit within their own historical range.
Price Usually Turns Before Earnings Do
Watch the price line and the earnings line together and you’ll notice price tends to move first, in both directions.
Micron is a clean recent example. The memory chip maker earned almost nine billion dollars in fiscal 2022, then swung to a loss of nearly six billion in fiscal 2023 as chip prices fell apart. The stock had already dropped hard through 2022, though, and it started climbing again in early 2023 while the company was still reporting losses quarter after quarter.
Anyone waiting for earnings to recover before buying missed a good chunk of that move. Anyone who bought around the turn of 2022 because profits looked fantastic was paying close to peak prices.
That lead time isn’t consistent, and it doesn’t always pay off. Sometimes the price turns up and then fails because the downturn drags on longer than expected. Still, on stock graphs that plot both lines, you can usually see the market pricing in the next phase well before the reported numbers catch up.
Average the Cycle, Then Check the Balance Sheet
A single year’s earnings can be wildly misleading, so it helps to think in terms of the average across a full cycle. Take eight or ten years of earnings, smooth them out, and ask what the stock costs relative to that figure. It’s rough, but far more stable than trailing twelve-month numbers.
Exxon Mobil shows why. In 2020 it reported its first annual loss in decades, around twenty-two billion dollars, and got dropped from the Dow Jones Industrial Average that August. Two years later it earned roughly fifty-six billion, a record. Neither year was normal. Both belonged to the same cycle.
The other thing to check is whether the company can survive the bad years. A cyclical carrying heavy debt into a downturn may have to cut its dividend or issue shares at terrible prices, sometimes worse. Profits come and go with the cycle, but the interest bills keep arriving regardless.
Conclusion
Reading stock graphs of cyclical companies mostly means unlearning habits that work fine on steadier businesses. The low multiple that looks like a bargain often shows up right at the peak, and the price tends to move long before the reported results do.
If I had to keep one rule, it’d be to look at two or three full cycles before deciding anything, and to make sure the company can get through the bad part of the next one. That part always shows up eventually.
