Indian Oil Corporation Ltd

Price story Before the numbers, the tape. A stock price moves through four repeating seasons: a flat base (stage 1), an advance (2), a top (3), a decline (4). Where the price sits in that cycle frames everything below.

Indian Oil Corporation Ltd trades at ₹140, in a downtrend and 15 weeks into that stage. That is −5.3% against its own 200-day average. It sits at 11% of a 52-week range of ₹134 to ₹187. On relative strength it is currently behind the NIFTY 500 on a trailing-13-week view (23 weeks and counting).

Today the stock is in a downtrend — week 15 of stage 4, confirmed. At ₹140 it trades −5.3% versus its 200-day average and sits at 11% of its 52-week range (₹134–₹187).

Against the market, two honest reads. Cumulative: over the last 10.4 years the stock moved +131% while the NIFTY 500 moved +282% — behind the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (23 weeks and counting; last ahead the week of 2026-03-13) — the ribbon below is that same metric, week by week.

What would end the trend, mechanically: two Friday closes in a row below the 200-day line. That is the exit rule — no debates.

Valuation P/E is the price of ₹1 of annual profit: how many rupees the market pays for each rupee the company earns in a year.

Indian Oil Corporation Ltd trades at 5.9× P/E, near the bottom of its own range — cheaper only 33% of the time. Its long-run median P/E is 8.4×, measured across 10.4 years of weekly readings. This places the multiple against the stock’s own record, and says nothing about what the business is worth.

Today's P/E of 5.9× is near the bottom of its own range — cheaper only 33% of the time, against a long-run median of 8.4× measured over 10.4 years of weekly readings. This is a comparison against the stock's own history — not a claim about what it is worth.

Why the multiple sits where it does: over the past year annual EPS moved +209.6% against a −0.6% price move — earnings outran the price, pushing the multiple DOWN its own range.

The price move, decomposed: over 5y, of the +15.3%/yr price move, ~+5.6%/yr came from earnings growth and ~+9.7 pp from the multiple (expanding); over 10y, of the +4.4%/yr price move, ~+24.7%/yr came from earnings growth and ~−20.3 pp from the multiple (compressing). The split is the honest approximate (price return minus earnings growth); it makes the rally itself visible instead of hiding it behind the percentile.

Put together: the multiple is low against its own past, so the story rests on the earnings line underneath it, not the multiple.

The PEG ratio and its quarterly curve, which only the second data source carries, are not drawn on this page: its two data sources disagree by up to 62% on reported income across 14 comparable periods. A figure two sources cannot agree on is not drawn — the gap is a decision, not missing data.

Stage: Mixed Every business sits somewhere on a fundamental arc, and this page names the spot before anything else. The last twelve quarters of revenue, profit and EPS growth — plus the return the business earns on its capital — are read as curves: Deteriorating (the curves are falling), Turning around (a trough has just formed and the last few quarters lift off it), Improving (the climb off the trough is sustained), Consistent (steadily positive with healthy returns), Topping out (still high but decelerating from the peak). When the curves genuinely disagree the read is Mixed; too little history is No read. CAGR (compound annual growth rate) is the smooth yearly pace that turns the starting value into the latest one — the fairest way to compare growth across different time spans. Read the columns together: if the 1-year number towers over the 10-year, recent growth is running hotter than the long-run trend. A dash means that window is not held, or the base year was a loss (where a growth rate is not meaningful).

Indian Oil Corporation Ltd reads as mixed on its fundamental arc. Mixed — no clean majority across the growth curves, ROCE lifting at 19.0% — the per-curve reads carry the story. The read is built from 8 quarters across 4 curves, on partial evidence.

Why it matters: when the curves disagree, the per-curve reads above matter more than any single verdict.

Return readings here are annual, not quarterly — read as level and direction only; they can confirm the growth curves but never drive the stage on their own.

A partial read: at least one curve is short, or the returns curve is not the computed quarterly series — hold the stage word a little more loosely.

4-Factor Sector Score

52.1/100 — rank 3 of 7 in Refineries · 76% evidence confidence

Indian Oil Corporation Ltd scores 52.1 out of 100 against the 7 companies it is compared with in Refineries, ranking 3. Balanced evidence: keep at normal research priority and require another comparable period before raising conviction.

The four contributions add to the total exactly: 20.6 + 12.8 + 13.8 + 4.9 = 52.1. This is the SAME number shown on the sector comparison — it is computed once, for the whole peer set, and read here.

What would change it: The read weakens if profit growth turns negative or margin improvement reverses while sector-relative strength deteriorates.

Revenue Revenue is the top line: everything the company billed its customers in the period.

Indian Oil Corporation Ltd reported ₹2,66,407 Cr of revenue in the Jun 26 quarter, +38.5% year on year. That is the 4th straight quarter of year-on-year growth. Over 10 years it has compounded at 8.5% a year. The last full year, FY26, came in at ₹7,84,415 Cr. The last four reported quarters add to ₹8,58,481 Cr.

FY26 revenue came in at ₹7,84,415 Cr (+3.5% on the year), capping 10 years at 8.5% compound. The latest quarter (Jun 26) printed ₹2,66,407 Cr, +38.5% year on year — the 4th consecutive quarter of year-over-year growth.

Pace check: the last four quarters averaged +13.3% growth against the decade's 8.5% — the current year is running faster than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew +13.5% over the last 4 quarters against +5.5%/yr over the last 8 — accelerating; TTM profit +111.7% vs +5.4%/yr — accelerating.

Operating margin Operating margin is what is left of every ₹100 of sales after running the business, before interest and tax. It is the cleanest read on pricing power and cost control.

Indian Oil Corporation Ltd's operating margin is 1.5% in the Jun 26 quarter, −5.5 percentage points against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged 2.4% to 11.0%. The current quarter is running below every full year in that window.

The latest quarter's operating margin is 1.5%, −5.5 pp against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged 2.4%–11.0%.

🚨 Why the margin moved: operating margin went −5.4 pp year on year while gross margin went −7.4 pp — the loss came mostly from the gross line: input costs and pricing.

Net profit Net profit is what survives every cost, interest and tax — the number EPS, dividends and book value all grow from.

Indian Oil Corporation Ltd posted a net loss of ₹1,141 Cr in the Jun 26 quarter. Full-year FY26 profit was ₹43,677 Cr. The 10-year compound rate is 13.4%. That loss is 0.4% of the quarter's revenue. The same quarter a year earlier earned ₹6,808 Cr. 2 of the last 12 reported quarters were loss-making.

Jun 26 profit was ₹−1,141 Cr, −116.8% year on year. On the full year, FY26 printed ₹43,677 Cr (+216.8%), and the 10-year compound rate is 13.4%.

🚨 Why profit moved: revenue contributed +38.5% and the margin −5.5 pp — the quarter was revenue-led despite a thinner margin.

Pace comparison, last four quarters: profit +164.5% vs revenue +13.3%. Profit is growing faster than sales — fixed costs are being spread over a bigger base, and each extra rupee of revenue drops more to the bottom line.

Cash flow — the router The P&L says what was earned; the cash-flow statement says what actually arrived. Operating cash flow (CFO) against profit is the cleanest lie detector in the accounts.

Over the last 3 fiscal years 181% of Indian Oil Corporation Ltd's reported profit arrived as operating cash — the cash follows the profit. In FY26 that was ₹76,142 Cr of operating cash against ₹43,677 Cr of profit. After ₹33,976 Cr of capital spending, ₹42,166 Cr was left as free cash.

FY26: operating cash of ₹76,142 Cr against reported profit of ₹43,677 Cr, leaving free cash of ₹42,166 Cr after ₹33,976 Cr of capital spending. Across the last 3 fiscal years the conversion rate is 181% of profit.

Cash-flow readings here are annual — that is the resolution our series carries, so this section moves once a year.

Why conversion sits at 181%: the cash cycle tightened 35 days between FY21 and FY26 — cash that used to wait in the cycle now reaches the bank sooner.

Router verdict: the bigger cash user is investment — capital spending ran 2.2× depreciation over three years, so the next section's job is to check what that build-out is buying.

Where the cash goes Working capital is the cash tied up between paying suppliers and getting paid: debtor days (customers owe), inventory days (stock waits), and the cash conversion cycle (the whole loop, in days of sales).

Indian Oil Corporation Ltd's cash conversion cycle runs 41 days in FY26, down from 76 days in FY21. Capital spending ran ₹1,14,501 Cr over the last 3 years. At FY26 sales of ₹7,84,415 Cr each day of that cycle holds about ₹2,149 Cr, so roughly ₹88,112 Cr sits inside the business at any moment.

FY26: debtors at 7 days, inventory at 68 days — roughly 2.2 months of stock waiting to sell; that is where the cash sits while it waits — for a full cycle of 41 days, tighter than FY21's 76.

The full loop: cash goes out to suppliers and production on day 0; stock waits 68 days to sell; customers pay about 7 days after that; and suppliers themselves are paid at 33 days — netting out to the 41-day cycle.

In money terms: at FY26 sales of ₹7,84,415 Cr, each day of the cycle holds about ₹2,149 Cr — so the 41-day loop keeps roughly ₹88,112 Cr sitting inside the business at any moment.

On the investment side: capital spending of ₹1,14,501 Cr over the last 3 fiscal years against ₹51,063 Cr of depreciation — the company is building well ahead of wear-and-tear. Capital work-in-progress stands at ₹82,897 Cr (FY26) — capacity paid for but not yet earning.

The synthesis: the cash is going into capacity, not disappearing into the cycle — the question becomes whether the new capacity earns.

Return on capital Return on capital employed (ROCE) is the profit the whole business earns on all the money in it — equity and debt together. It is the single best test of whether growth creates value or just size.

Indian Oil Corporation Ltd earns a ROCE of 19% in FY26. That is up from a trough of 5% in FY20. A return-on-invested-capital spread against the cost of capital is not computable from what is held here. The wiring behind it is 5.6% net margin on 1.48× asset turns.

FY26 ROCE is 19%, recovered from a FY20 trough of 5% — the full ladder below shows the fall and the climb, undoctored.

Why the return is what it is — the wiring (FY26): 5.6% net margin × 1.48× asset turns × 2.41× balance-sheet leverage ≈ 20.0% on equity. Margin does its share; leverage is a meaningful part of the equation.

The quarterly return curves and the return-on-invested-capital overlay, which only the second data source carries, are not drawn on this page: its two data sources disagree by up to 62% on reported income across 14 comparable periods. A figure two sources cannot agree on is not drawn — the gap is a decision, not missing data.

Debt Debt-to-equity says how much of the business is funded by borrowings; interest cover says how many times operating profit pays the interest bill. Low and high, respectively, is the safe corner.

Indian Oil Corporation Ltd carries ₹1,31,822 Cr of borrowings against ₹2,19,518 Cr of equity in FY26, a debt-to-equity of 0.60. Operating profit covers the interest bill 9×. Over 5 years borrowings went from ₹1,16,649 Cr to ₹1,31,822 Cr. Capital spending ran ₹1,14,501 Cr across the last 3 of those years.

FY26: borrowings of ₹1,31,822 Cr against equity of ₹2,19,518 Cr — a debt-to-equity of 0.60. Operating profit covers the interest bill 9×. Over 5 years borrowings went from ₹1,16,649 Cr to ₹1,31,822 Cr while capital spending ran ₹1,14,501 Cr in just the last 3 — part of the build-out is riding on borrowed money.

The total-debt and debt-to-equity series, which only the second data source carries, are not drawn on this page: its two data sources disagree by up to 62% on reported income across 14 comparable periods. A figure two sources cannot agree on is not drawn — the gap is a decision, not missing data.

Ownership Who owns the stock, quarter by quarter: promoters (the controlling owners), foreign and domestic institutions, and the public. Steady accumulation by people close to the numbers is a signal; a quiet register is also an answer.

Foreign institutions added 1.3 points of Indian Oil Corporation Ltd over 8 quarters, the biggest move on the register. That takes foreign institutions to 9.1% of the company. Domestic institutions moved −0.5 points over the same window, to 9.5%. The register is read on the four disclosed classes only; nothing is inferred between filings.

The register over the last two years — Foreign institutions: +1.3 points over 8 quarters to 9.1%; Domestic institutions: −0.5 points over 8 quarters to 9.5%; Promoters: +0.0 points over 8 quarters to 51.5%.

Why the register moved: foreign institutions drove it (+1.3 points), absorbed on the other side by domestic institutions (−0.5 points) — steady accumulation by institutions reading the same numbers this page reads.

Safety line The Z-score estimates how far a company sits from balance-sheet distress — above roughly 3 is safe, below roughly 1.8 is the danger zone. It was built for manufacturers, so it is not applied to banks and lenders.

Indian Oil Corporation Ltd: the Z-score is not available for this stock, so we say so rather than invent one. It is a distance-to-distress estimate from the balance sheet, not a forecast of failure. The debt, cash-flow and return sections above carry the balance-sheet evidence this page does hold, and each of them states its own reporting date.

The safety line in one sentence: the Z-score is not available for this stock, so we say so rather than invent one.
