The year 2026 is seeing increased hype in India’s primary market. As per the latest reports in FY26 till date, 112 companies have raised Rs 1,78,963 crore through mainboard IPOs, whereas 144 companies have received SEBI approval to raise around Rs 1.75 lakh crore, while another 63 companies are still in the pipeline awaiting regulatory clearance to conduct IPOs. With so many IPOs lined up, the real challenge is not finding an IPO; it is finding the right one.
Many retail investors use indicators such as GMP, subscription status, and other details to compare them with those of the IPO company’s peers to decide whether to invest. While helpful, most of these signals are available only after the subscription window opens. But how can investors identify if a sector has strong momentum before an IPO opens? This is where the market heatmaps come in. In this blog, we will explore how investors can identify promising IPOs using market heatmaps.
Check sector performance before reading the DRHP
Before subscribing to any upcoming IPOs, one needs to evaluate the sector’s current performance. The sectoral heatmap displays sectors in a colour-coded format, with green indicating positive performance and red indicating negative performance.
The intensity of the colour indicates the degree of the performance, with brighter colours indicating stronger momentum. For example, if a sector is witnessing sustained green momentum, it indicates strong buying interest in that sector. If a company brings an IPO in this sector, the company listing will have favourable conditions.
On the contrary, if a sector is persistently in the red while the overall market is stable, this indicates that the sector is facing some issues. This weak sector sentiment may impact the listing performance of an IPO, even if fundamentals are strong.
Rotation is often seen when leadership moves from one group of sectors to another over several sessions, rather than appearing as a one-day colour flip. Investors should analyse stock heatmaps over a period of time, not just one day.
Evaluate trade volume in the sector
The heat map provides directional insights, and trade volume adds conviction. Volume heatmaps illustrate how actively stocks are being traded. Darker colours represent high trading activity, signalling investors’ interest. By comparing price and volume together, traders can determine whether a price move is credible or simply the result of low participation.
When listed players in the sector rally on high volume, it shows genuine institutional accumulation. High volume supports momentum and sustains it. In contrast, thin volume behind a green sector is a caution sign, not a confirmation.
Cross-check with IPO fundamentals
A strong sector heatmap represents a promising IPO. It narrows the investor’s shortlist, but for better results, investors should also evaluate the company’s fundamentals. Some of the best-performing sectors for IPOs in 2025 were manufacturing, capital goods, and niche technology. These IPOs had listing gains of 40% to 70%. Most of these companies had clear revenue visibility, a scalable business model, low debt levels, and the backing of anchor investors.
After heat maps indicate that the sector is in strong momentum, investors should evaluate the DRHP filed with SEBI, check anchor investor allocations, use of proceeds, and valuation relative to peers, among other factors, to clearly gauge the IPO’s prospects.
Conclusion
With nearly 200 companies queued to bring their IPOs in 2026, investors who will have successful IPO investments will be those who conduct in-depth research before investing. A heatmap shows which sectors are gaining momentum, where institutional capital is flowing, and which sectors are underperforming.
Heatmap insights, combined with DRHP study and valuation checks, provide investors with an edge in identifying IPO listing potential before it becomes obvious.
