BSE 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.

BSE Ltd trades at ₹3,447, in a confirmed uptrend and 164 weeks into that stage. That is +5.4% against its own 200-day average. It sits at 64% of a 52-week range of ₹2,093 to ₹4,194. On relative strength it is currently behind the NIFTY 500 on a trailing-13-week view (8 weeks and counting).

Today the stock is in a confirmed uptrend — week 164 of stage 2, confirmed. At ₹3,447 it trades +5.4% versus its 200-day average and sits at 64% of its 52-week range (₹2,093–₹4,194).

Against the market, two honest reads. Cumulative: over the last 9.5 years the stock moved +2,802% while the NIFTY 500 moved +210% — ahead of the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (8 weeks and counting; last ahead the week of 2026-06-25) — 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.

From the price. Price stage 2, week 164 — above its 200-day line, relative strength falling.

From the research. A 150-year-old exchange remade in 30 months — derivatives operating leverage is compounding at scale while the market prices it for perfection.

🚨 Where they disagree. PE peaked at 86.7× (March 2024) and has been contracting. At 82nd percentile (64.2×, 2.04× median), the stock is expensive by any historical measure. However, the EARNINGS_DISCONNECT cycle (earnings growing faster than PE) means the valuation is improving through earnings growth, not multiple re-rating. FIIs have been buying consistently — shareholding grew from 8.77% (Jun 2023) to 18.14% (Jun 2025), a 9.37pp increase. The bull case requires earnings to continue growing 40-60% annually to compress the PE toward the median.

What is proven. A 150-year-old exchange remade in 30 months — derivatives operating leverage is compounding at scale while the market prices it for perfection.

What is not proven yet. PE 64.2× (2.04× median, 82nd percentile); any derivatives volume normalization compresses earnings AND multiple simultaneously — the classic exchange dual-compression trap.

Layer 1 read, 19 July 2026 — KEEP. Real, still-growing exchange earnings but the stock has already captured the re-rating — extended and richly priced with management-consistency strain. BSE's earnings engine is genuine and expanding — FY26 net profit up ~88% on fixed-cost operating leverage (opex +20% vs revenue +59%). But the stock is deep into innings 7: 25.3x off its trough, 159 weeks in Stage 2, extreme MoS -44.3%, PE at the 82nd percentile, and two guidance MISSes on co-location pricing and the SGF halt with a FAILED validation. Real business, spent move — P2 ranked low, not a DROP.

What would change Layer 1’s mind. If Q1FY27 derivatives daily premium turnover falls below ₹12,000Cr (bear-scenario trigger) OR CAS go-live slips past August 2026, the earnings base that justifies the extended price weakens and the verdict flips toward DROP.

Layer 2 read, 19 July 2026 — BENCH. Real earnings, no margin of safety — extended winner in a topping, peak-margin sector → BENCH. BSE's earnings engine is genuine — profit up ~88% on organic operating leverage (opex +20% vs revenue +59%), and the sector view is ALIGNED and EARNINGS_LED, so this is not a value that is falling apart. But the sector is TOPPING and carries a deterministic peak-margin value-trap: record OPM (92nd percentile) makes the trailing PE look milder than it is, and normalizing margins pushes the multiple to the 98th percentile. On top of that the stock is extended (25x off its trough, 159 weeks in an uptrend, at its cycle peak) with an extreme MoS of -44% — the easy re-rating is already captured, so we hold it on the bench rather than advance it.

What would change Layer 2’s mind. Evidence that the record OPM (92nd %ile) is STRUCTURALLY durable rather than cyclical-peak — e.g. a durable step-change in derivatives/co-location pricing power that survives the CERC market-coupling decision — would flip the peak-margin-trap read and could turn BENCH toward ADVANCE. Conversely, OPM rolling over (the boom starting to roll) plus a CERC adverse ruling would push it toward DROP.

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

BSE Ltd reported ₹1,566 Cr of revenue in the Jun 26 quarter, +63.5% year on year. That is the 12th straight quarter of year-on-year growth. Over 10 years it has compounded at 23.2% a year. The last full year, FY26, came in at ₹5,124 Cr. The last four reported quarters add to ₹5,442 Cr.

Why this happened. BSE launched equity derivatives 30 months ago from near-zero. By FY26 close, Sensex options are among the globally most-traded index options. Thursday expiry transition completed — non-expiry volumes now 5% of total, indicating emerging depth beyond single-expiry concentration. New monthly index derivatives launched (BSE Focused IT — May 2026; Focused Midcap and Sensex Next 50 approved) targeting longer-tenor participants. FPI count expanding from 100 to 520 (target 800). Active brokers 587 (target 700+). The derivatives franchise is in early innings of institutional deepening, not a mature market-share story.

FY26 revenue came in at ₹5,124 Cr (+59.5% on the year), capping 10 years at 23.2% compound. The latest quarter (Jun 26) printed ₹1,566 Cr, +63.5% year on year — the 12th consecutive quarter of year-over-year growth.

Pace check: the last four quarters averaged +60.4% growth against the decade's 23.2% — the current year is running faster than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew +60.7% over the last 4 quarters against +68.0%/yr over the last 8 — rolling over; TTM profit +76.7% vs +117.8%/yr — rolling over.

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.

BSE Ltd's operating margin is 67.0% in the Jun 26 quarter, +2.0 percentage points against the same quarter a year ago. That is the widest this company has ever printed on a full-year basis. Across 13 fiscal years the operating margin has ranged 21.0% to 68.0%. The current quarter sits inside that band.

Why this happened. BSE's revenue is predominantly transaction-based (derivatives charges, listing fees, co-location) while ~49% of operating costs are fixed infrastructure. This creates powerful operating leverage as derivatives volumes scale. In FY26, revenue grew 59% YoY while operating expenses grew only 20%, expanding EBITDA margins from 51% to 64%. Q4 FY26 saw OPM hit 67% — the highest in the dataset. The clearing-and-settlement expense line (53% of total opex) is partially variable (tied to contract counts), creating an inverse premium-cost relationship in high-volatility quarters. The leverage is structural, not cyclical — it persists as long as derivatives volumes grow.

The latest quarter's operating margin is 67.0%, +2.0 pp against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged 21.0%–68.0%, and FY26's 68.0% is the top of that band — a record year.

Why the margin moved: operating margin went +1.5 pp year on year while gross margin went +0.0 pp — the gain came mostly below the gross line: operating leverage, with costs spread over a bigger revenue base.

Worth repeating from the valuation section: cheap against its own history on record margins is not the same thing as cheap — a record margin flatters every ratio built on top of it.

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

BSE Ltd earned ₹873 Cr of net profit in the Jun 26 quarter, +62.3% year on year. It is the 8th consecutive quarter of growth. Full-year FY26 profit was ₹2,487 Cr. The 10-year compound rate is 30.2%. That is 55.7% of the quarter's revenue. The same quarter a year earlier earned ₹538 Cr.

Jun 26 profit was ₹873 Cr, +62.3% year on year — the 8th consecutive quarter of growth. On the full year, FY26 printed ₹2,487 Cr (+88.1%), and the 10-year compound rate is 30.2%.

Why profit moved: revenue contributed +63.5% and the margin +2.0 pp — the quarter was margin-led: most of the profit growth came from keeping more of each sale.

Pace comparison, last four quarters: profit +89.2% vs revenue +60.4%. 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 134% of BSE Ltd's reported profit arrived as operating cash — the cash follows the profit. In FY26 that was ₹3,104 Cr of operating cash against ₹2,487 Cr of profit. After ₹524 Cr of capital spending, ₹2,580 Cr was left as free cash.

Why this happened. BSE voluntarily contributed 5% of transaction-linked revenue (later described as profits) to the Core SGF monthly. Upon exceeding 150% of the minimum regulatory requirement in Q3 FY26, the rate was halved to 2.5% per quarter. This adds a recurring PAT tailwind without any pricing or volume action. The May 2026 concall confirmed this is ongoing — not a one-time benefit. The note: Tijori flagged that management contradicted whether the threshold trigger was a halt (Nov 2025 guidance) or rate-reduction (actual May 2026 outcome), creating some forward calibration uncertainty on the exact size of remaining benefit.

FY26: operating cash of ₹3,104 Cr against reported profit of ₹2,487 Cr, leaving free cash of ₹2,580 Cr after ₹524 Cr of capital spending. Across the last 3 fiscal years the conversion rate is 134% 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 134%: the cash cycle tightened 12 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 2.3× 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).

BSE Ltd's cash conversion cycle runs 39 days in FY26, down from 51 days in FY21. Capital spending ran ₹832 Cr over the last 3 years. At FY26 sales of ₹5,124 Cr each day of that cycle holds about ₹14.0 Cr, so roughly ₹547 Cr sits inside the business at any moment.

FY26: debtors at 39 days (an asset-light business — no inventory to speak of) — for a full cycle of 39 days, tighter than FY21's 51.

In money terms: at FY26 sales of ₹5,124 Cr, each day of the cycle holds about ₹14.0 Cr — so the 39-day loop keeps roughly ₹547 Cr sitting inside the business at any moment.

On the investment side: capital spending of ₹832 Cr over the last 3 fiscal years against ₹367 Cr of depreciation — the company is building well ahead of wear-and-tear. Capital work-in-progress stands at ₹77.0 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.

BSE Ltd earns a ROCE of 60% 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 48.5% net margin on 0.38× asset turns.

FY26 ROCE is 60%, 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): 48.5% net margin × 0.38× asset turns × 2.01× balance-sheet leverage ≈ 37.0% on equity. Margin is doing the heavy lifting; 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 39% 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.

BSE Ltd carries ₹0.0 Cr of borrowings against ₹6,673 Cr of equity in FY26, a debt-to-equity of 0.00. Operating profit covers the interest bill north of 100×. Over 5 years borrowings went from ₹0.0 Cr to ₹0.0 Cr. Capital spending ran ₹832 Cr across the last 3 of those years.

FY26: borrowings of ₹0.0 Cr against equity of ₹6,673 Cr — a debt-to-equity of 0.00. Operating profit covers the interest bill north of 100×. Over 5 years borrowings went from ₹0.0 Cr to ₹0.0 Cr while capital spending ran ₹832 Cr in just the last 3 — the build-out is being paid for out of cash, not debt.

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 39% 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.

Domestic institutions added 12.5 points of BSE Ltd over 8 quarters, the biggest move on the register. That takes domestic institutions to 24.1% of the company. Foreign institutions moved +10.2 points over the same window, to 21.3%. The register is read on the four disclosed classes only; nothing is inferred between filings.

Why this happened. SEBI issued a directive requiring both exchanges to implement Closing Auction Session by August 3, 2026, with pre-open auction upgrade by September 7, 2026. This adds incremental transaction volume during the closing period — every additional trade generates transaction charges at BSE's revenue rates. This is a regulatory tailwind requiring no competitive advantage: it is mandatory and BSE will capture its proportionate share. The incremental PAT contribution is estimated at ₹5-10 Cr/quarter initially, scaling with volumes over 12-18 months.

The register over the last two years — Domestic institutions: +12.5 points over 8 quarters to 24.1%; Foreign institutions: +10.2 points over 8 quarters to 21.3%.

Why the register moved: domestic institutions drove it (+12.5 points), alongside foreign institutions (+10.2 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.

BSE 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.

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.

BSE Ltd trades at 49.6× P/E, mid-range by its own standards (65th percentile). Its long-run median P/E is 32.0×, measured across 9.5 years of weekly readings. This places the multiple against the stock’s own record, and says nothing about what the business is worth.

Why this happened. Co-location is BSE's fastest-growing segment. Post revised throttle charges framework (July 2025), quarterly revenue accelerated from ₹27 Cr (Q1 FY26) to ₹46 Cr (Q2 FY26) — a 70% QoQ jump in a single quarter. Total rack capacity targeting ~600 (vs 300 at start of FY26). Co-location is high-margin and recurring — algo traders have structural switching costs in their connectivity infrastructure. Management has been inconsistent on the pricing strategy (guided 'meaningful increases soon' in May 2025; walked back to 'no plans to increase' in Feb 2026), but revenue is growing regardless of whether pricing is the driver or utilization is.

Today's P/E of 49.6× is mid-range by its own standards (65th percentile), against a long-run median of 32.0× measured over 9.5 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 +87.8% against a +38.9% price move — earnings outran the price, pushing the multiple DOWN its own range.

The price move, decomposed: over 5y, of the +93.6%/yr price move, ~+73.4%/yr came from earnings growth and ~+20.2 pp from the multiple (expanding). 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 full 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 39% 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).

BSE Ltd reads as mixed on its fundamental arc. Mixed — growth is normalizing off a hyper-growth base: profit growth has eased from +133.5% at its peak to +76.7% but is still expanding, ROCE lifting at 60.0%. The read is built from 9 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

75.0/100 — rank 2 of 3 in Exchanges · 79% evidence confidence

BSE Ltd scores 75.0 out of 100 against the 3 companies it is compared with in Exchanges, ranking 2. Confirmed research leader: earnings, capital efficiency and relative strength agree. Move to management, catalyst and risk diligence.

The four contributions add to the total exactly: 32.8 + 22 + 8.5 + 11.7 = 75. 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.

Said versus delivered

What BSE Ltd's management promised, set against what actually arrived — 4 tracked promises on the record. Read straight from the company’s own earnings calls. A promise that slipped stays on this page after it is met.

SGF Policy - Halt vs. Rate Reduction at the 150% Threshold · 7 May 2026. In the Nov 2025 call, management explicitly stated and confirmed in Q&A that upon reaching 150% of the minimum SGF requirement, voluntary contributions would be halted entirely until the excess was consumed. In the May 2026 call, management disclosed that upon crossing that threshold they instead reduced the contribution rate from 5% to 2.5% rather than halting, directly contradicting the stated policy. Analysts modeling BSE's forward P&L based on Nov 2025 guidance would have expected SGF charges to cease, not merely continue at half the prior rate.

SGF Contribution Base - Transaction Revenue vs. Profits · 7 May 2026. In the Nov 2025 call, management clearly defined the voluntary SGF contribution base as transaction-related revenue at 5% per month. In the May 2026 call, the CEO retroactively described the identical policy as applying 5% to profits rather than transaction revenue. These are materially different bases - in Q2 FY26, transaction revenues were Rs. 794 crores versus net profit of Rs. 558 crores - making analysts' prior calibration of expected SGF deductions unreliable and raising questions about management's precision in describing its own internal policies.

🚨 Smart Order Routing - Early Positive Traction Reversed to No Progress · 7 May 2026. In the Nov 2025 call, management reported that common contract note implementation and SOR engagement were yielding positive early results with BSE cash volumes rising among both DIIs and FIIs. Just six months later in the May 2026 call, management completely reversed this assessment, stating SOR had not taken off and attributing the failure entirely to the competitor exchange holding pending SOR applications for over six months. Management offered no explanation for why the positive momentum they described in Nov 2025 did not persist, nor why the competitor-related obstacle was not flagged to investors earlier.

SGF Contribution Policy Pivot · 9 February 2026. Management previously stated that Settlement Guarantee Fund (SGF) requirements were too complex to project linearly or provide periodically. The latest call contradicts this by implementing a specific formula (5% of transaction revenue capped at a 150% threshold), providing the exact predictability they previously claimed was difficult to establish. Earlier call (May 2025): “A linear relationship cannot be put in place... prohibits and prevents and makes it difficult for us to project the requirements of SGF.” Later call (Feb 2026): “BSE”.
