A company announces a ₹1,000 crore plant. A few months later, its profit drops, yet the share price hardly moves. Many new investors read that as a warning sign. It usually has a simpler explanation: the capex cycle.
A capex cycle is a stretch of time when companies spend heavily on factories, machines, and technology. Profit often dips first because costs begin before the plant sells anything, and it rises later if demand holds. This guide explains how that works in India, with a worked example.
Quick Answer
A capex cycle is a period when companies spend heavily on long-lasting assets such as factories and machinery. Profit often dips at first, because depreciation and interest costs begin before the new asset earns anything. If demand is strong, sales and profit rise in later years. If demand is weak, profit stays under pressure.

What Is a Capex Cycle?
Capex is short for capital expenditure. It is the money a company spends on things that last for years, such as a factory, land, machinery, or a large software system. Salaries, electricity, and raw materials are running costs, so they do not count.
A capex cycle is the pattern that repeats. Companies spend when business looks good, finish the projects, wait for sales to build, then slow down until the next round. You can spot it in one company, in a sector or across the whole economy.
The accounts explain why profit moves the way it does. A new plant goes on the balance sheet first, and only a slice of its cost reaches the profit statement each year as depreciation. Depreciation is an accounting charge that spreads the cost over the plant’s useful life.
Interest on a loan taken for construction is usually added to the plant’s cost until the plant is ready. After that, it is charged to profit.
India has been through this before. Listed company capex, excluding financial firms, was about ₹6 trillion at its 2012 peak and reached about ₹12.6 trillion in FY26. In US dollar terms, the rise is small, from about USD 131 billion to USD 143 billion.
How Does a Capex Cycle Work?
Alice Blue’s community post on capital goods gives the order. Orders rise first, revenue follows once execution begins, margins improve with scale and capacity use, and cash generation decides how sustainable it all is. Here is the same story from one company’s side.
- Demand picks up, or the government offers incentives, and a company decides it needs more capacity.
- It arranges money from savings, a bank loan, bonds, or new shares.
- It places orders with engineering and equipment firms. Its order book, the value of work won but not yet delivered, starts growing.
- The plant gets built. Cash goes out, and nothing comes in yet.
- The plant starts running, and depreciation begins. A ₹1,000 crore plant used for 20 years adds ₹50 crore of depreciation a year.
- Orders fill the plant. Fixed costs stay the same while sales grow, so margins can improve.
- After a few years, ROCE (return on capital employed) shows the result. It tells you how much profit the company earns on each rupee invested in the business.
How Does a Capex Cycle Affect Earnings?
The company below is made up, so read it as a teaching example and not as a stock. Kaveri Cement Ltd has 100 crore shares. It spends ₹1,000 crore on a new plant, funded by a ₹600 crore loan at 9% and ₹400 crore of its own cash.
The plant adds two yearly costs once it starts running. Depreciation is ₹50 crore (₹1,000 crore divided by 20 years). Interest is ₹54 crore (9% of ₹600 crore).
₹ crore | Before the plant | Year 1 | Year 3 |
Sales | 5,000 | 5,150 | 6,200 |
Operating profit (EBITDA) | 800 | 798 | 1,023 |
Depreciation | 200 | 250 | 250 |
Interest | 40 | 94 | 85 |
Profit before tax | 560 | 454 | 688 |
Net profit after 25% tax | 420 | 340.5 | 516 |
EPS (₹) | 4.2 | 3.4 | 5.2 |
EBITDA is operating profit before interest, depreciation and tax. EPS, or earnings per share, is net profit divided by the number of shares.
In Year 1 the plant is only partly used, so sales barely move while depreciation and interest jump. Net profit falls about 19%. By Year 3 sales have grown and part of the loan is repaid, so profit sits about 23% above the starting level.
Year 3 sales are 24% above the starting level, while operating profit is about 28% higher. Costs such as plant rent and supervisors’ salaries stay the same when sales rise, so each extra rupee of sales adds more to profit. Analysts call this operating leverage.
Why Does the Share Price Move Differently?
A share price follows what investors expect, and last quarter’s profit is only part of that. When Kaveri Cement announces the plant, buyers may already be thinking about Year 3. The stock can hold steady or even rise while reported profit falls.
It can also go the other way. If demand softens while the plant is being built, the Year 3 hope fades and the price can fall before any result shows it.
How Does It Affect Capital Goods Stocks?
Capital goods are the machines and equipment that other businesses use to make their own products. Companies that build them tend to feel a capex cycle first, because orders arrive before sales do.
Larsen & Toubro’s July to September 2026 quarter shows how this looks. Revenue rose 16% to ₹78,750 crore, and net profit rose 33% to ₹5,202 crore. Operating profit (EBITDA) was ₹6,845 crore, up only 0.6%. The EBITDA margin, which is the share of each ₹100 of sales left as operating profit, fell to 8.7% from 10% a year earlier.
The order book stood at ₹8,53,514 crore on 30 September, up 15% since March. You can size it yourself. Sales for April to September were about ₹1,46,700 crore, which is Q1’s ₹67,942 crore plus Q2’s ₹78,750 crore. Doubling that gives about ₹2,93,400 crore for a year, so the order book is roughly 2.9 times a year’s sales. This is a rough estimate, not a company figure.
A large order book still has limits. Customers can pay late, costs can rise on fixed-price contracts, and a popular theme may already be priced into the stock.
How to Check If Capex Is Paying Off
Three simple checks help.
- Compare capex with depreciation. Spending ₹200 crore against ₹100 crore of depreciation gives 2x. A ratio near 1x means a company is mostly maintaining what it has. Across listed Indian companies, it was about 1.9x in FY26, which points to expansion.
- Check fixed asset turnover, which is the sales earned for every ₹1 of plants and machines. If a company keeps adding assets while this number falls, the new capacity may be sitting idle.
- Follow ROCE over three to five years. If profit on capital rises after the spending, the cycle is paying off.
Key Features of a Capex Cycle
- Orders show up before sales, so capital goods and construction firms show the change first.
- Depreciation rises once a plant starts, and it lowers profit even though no cash leaves that year.
- Debt often rises, which means more interest until it is repaid.
- The revival is uneven. Reports describe it as concentrated in a few fast-growing sectors, with private companies winning a rising share of orders at firms like L&T and Tata Projects.
Advantages of Tracking Capex Cycles
- You can tell whether a profit dip comes from a plant being built or from falling sales. Those two situations call for different decisions.
- Order books give an early hint about sales over the next few quarters. Free cash flow also makes more sense once you know capex. It equals operating cash flow minus capex, so heavy spending lowers it for a while.
Risks and Limitations
- Demand is the main risk. If the new capacity does not sell, the company carries depreciation and interest on an idle plant. Projects can also run late or cost more than planned.
- Higher interest rates hurt companies that borrowed to expand. The West Asia conflict has been flagged as a threat to India’s private capex revival, and it weighed on L&T’s project execution in Q1 FY27. Higher fuel and raw material costs also cut corporate profits.
- On the behaviour side, many beginners buy a stock only because capex is trending. Some read a big order book as guaranteed profit. Others sell in a panic when EPS dips for a reason the company already explained.
Is the Capex Cycle Good for Beginners?
It is worth learning, because it explains results that look odd at first. It is hard to trade, since the effects play out over years. Five habits help.
- Find the capex plan in the annual report or earnings call and note how it will be funded.
- Compare growth in depreciation and interest with growth in sales over several years.
- Track ROCE.
- Spread your money across sectors so one theme does not carry the whole portfolio.
Growth Capex vs Maintenance Capex
Parameter | Growth capex | Maintenance capex |
Purpose | Add capacity or enter a new area | Keep existing assets running |
Effect on sales | Rises later | Stays about the same |
Effect on profit | Dips first, may rise later | Little change |
Example | A new cement plant | Replacing worn machines |
Capex against depreciation | Well above 1x | Close to 1x |
What to check | ROCE on the new money | Cost control |
Common Mistakes to Avoid
- Judging an expansion by one quarter. Profit usually dips first, so read the plan and the timeline.
- Ignoring debt. Check debt-to-equity, which compares what a company owes with its own money, and how easily profit covers interest.
- Treating orders as profit. An order becomes revenue only after delivery, and margin and payment timing decide what is left.
- Joining a theme late. By the time capex fills the headlines, the price may already include the good news.
- Treating every sector alike. A data centre build and a cement expansion have different demand and payback periods.
Who Should Track Capex Cycles?
Long-term investors and swing traders who follow capital goods, infrastructure, power, cement, or metals get the most from it. A swing trader holds a stock for a few days to a few weeks. Mutual fund investors can use it to understand what drives a thematic fund, which invests in one theme.
Intraday traders will find it less useful, because capex effects play out over quarters and years while an intraday trade lasts hours.
Conclusion
A capex cycle explains why spending and earnings do not move together. Depreciation and interest start early, while higher sales and margins need time and steady demand. Before you judge a profit dip, find out what the company spent, how it paid for it, and whether orders are turning into revenue. ROCE, debt, and free cash flow help you test the story. Capex news is a reason to read the company’s annual report, and the annual report will show whether the money is earning a return.
