Indian equity markets have been in the grip of sharp volatility — geopolitical tensions from the Iran conflict and Donald Trump's unpredictable policy statements have sent retail investors scrambling for exits. Yet quietly, in the background, the promoters of some of India's well-known listed companies have been doing the opposite: buying.
Promoter buying — when the founders or controlling shareholders of a company purchase more of its own stock — is often cited as a bullish signal. But the reality is far more nuanced. Let's decode what's actually happening.
"Promoter buying is not always a straightforward positive signal. Each case requires detailed analysis of company fundamentals, government policies, and the broader market context."
Why do promoters buy during a correction?
There are multiple, often coexisting, reasons that drive insider accumulation. Understanding the motivation is key to interpreting the signal correctly.
- Growth conviction: Confidence in faster-than-expected company growth or an upcoming positive catalyst
- Corporate action: Internal events such as a merger, spinoff, or strategic restructuring that the promoter expects to unlock value
- Undervaluation: The stock appears cheap relative to intrinsic value at current prices
- Defensive buying: Action against short-sellers who deliberately drive down prices to profit from the decline
- Pledge protection: Buying to protect pledged shares used as loan collateral, preventing margin calls
- Sentiment restoration: Rebuilding retail investor confidence after a period of losses or negative news
- Control consolidation: Increasing voting power or maximising dividend income by growing their shareholding stake
Case study: Borosil Renewables
On March 31, 2026, the promoters of Borosil Renewables purchased 52,577 shares at an average price of ₹380.6 — a transaction worth approximately ₹2.12 crore. Modest in absolute terms, but the context makes it significant.
Financial snapshot
| Period | Net Profit / Loss (₹ Crore) | Notes |
|---|---|---|
| FY2024 | −50 | Margin pressure from cheap imports |
| FY2025 | −87 | Continued losses |
| Trailing 12 months | −71 | Loss, but operating profit improving |
| Sep 2025 quarter | +62 | Return to quarterly profitability |
| Dec 2025 quarter | +100 | Sharp recovery; 31% operating margin |
The policy pivot that changed everything
Borosil manufactures solar glass — a product whose fortunes are tightly tied to government trade policy. When anti-dumping duties on Chinese solar glass imports were removed in August 2022, cheap imports flooded the Indian market and decimated margins. The company bled losses for three consecutive years.
The tide turned when the government recently re-imposed anti-dumping duties on solar glass imports from China and Vietnam for five years. Combined with a major capacity expansion underway in Bharuch, Gujarat — funded via a ₹371 crore preferential issue — the promoters appear to be buying in anticipation of a sustained profitability recovery.
Shareholding pattern
| Quarter Ending | Promoter Holding (%) |
|---|---|
| March 2025 | 62.20% |
| June 2025 | 61.93% |
| September 2025 | 61.85% |
| December 2025 | 58.77% |
The drop in promoter holding from 62.2% to 58.77% was not due to selling — it resulted from dilution caused by the preferential issue used to raise expansion capital. The recent open-market buying signals renewed conviction.
Conclusion: Promoter buying is likely linked to anticipated benefits from the re-imposed anti-dumping duties and the ongoing capacity expansion, both of which should structurally improve margins and restore profitability. There is also a secondary motive: rebuilding market confidence after years of reported losses.
Case study: Jindal Stainless
Over the past two months, Jindal Stainless promoters have acquired shares worth approximately ₹487 crore — an aggressive accumulation by any measure, especially against a falling market backdrop.
Two key developments frame this buying:
- The company recently announced a ₹5,400 crore strategic investment in capacity expansion via a joint venture.
- Management has signalled that detailed volume growth plans for the next two to three years will be disclosed in the near future.
Promoter buying ahead of a major corporate announcement often reflects an insider's conviction that the market has not yet priced in upcoming positive news. The Q4 earnings announcement will be crucial in confirming or qualifying this thesis — investors should await those results before drawing firm conclusions.
Case study: Bajaj Finance
Bajaj Finance promoters have been steadily accumulating from December 2025 through April 2026, purchasing shares worth roughly ₹374 crore over that period.
Valuation context
| Metric | Current Value | 10-Year Median |
|---|---|---|
| Price-to-Earnings (PE) ratio | 28.2× | 44.1× |
| Price-to-Book (P/B) ratio | 4.98× | 8.1× |
The story here is one of valuation. Bajaj Finance is trading at a PE of 28.2 against a 10-year median of 44.1 — and at a P/B of 4.98 versus a historical median of 8.1. For NBFCs and financial companies, the price-to-book ratio is a more meaningful yardstick than PE, since the core business is financial assets. At roughly half its historical P/B median, promoters may simply see the stock as historically cheap — a conviction buy rather than a defensive action.
For financial companies like Bajaj Finance, always assess valuation using price-to-book rather than price-to-earnings. A bank or NBFC trading at half its historical P/B median is a fundamentally different proposition from a similarly PE-discounted manufacturing company.
What retail investors should do
Promoter buying in a falling market is worth tracking, but it is a starting point for research — not a buy signal in itself.
For each company showing insider accumulation, ask these questions before acting:
- Are the underlying business fundamentals improving or deteriorating?
- Is there a policy tailwind, corporate event, or strategic announcement on the horizon?
- Is the promoter buying from a position of genuine conviction, or is this defensive (pledge protection, sentiment management)?
- How does the current valuation compare to the company's own historical averages?
In the current volatile environment, understanding the why behind promoter accumulation is the edge that separates informed investing from herd behaviour. Six additional companies have shown recent promoter buying activity beyond the three covered here — but the principle remains the same: context is everything.
"Promoter buying is occurring in a volatile market, often signalling potential growth or defensive corporate measures. Each case requires detailed analysis of company fundamentals, government policies, and market context to interpret promoter intent accurately."
