Diamond Power Infrastructure up 10% as mcap tops ₹10k cr

Stock jumps to near ₹192 on May 14

Diamond Power Infrastructure Ltd (NSE: DIACABS, BSE: 522163), a cables and conductors maker, saw its shares rally about 10% on May 14, 2026. In the market snapshot provided, the stock was quoted around ₹191.99 on the NSE and ₹191.75 on the BSE. The move put the company back in focus after a sharp run-up over the past year, as well as heightened interest around large order opportunities.

The rally was also reflected in the company’s market capitalisation, which crossed the ₹10,000 crore mark. PTI reported that the market valuation stood at more than ₹10,000 crore after the session. The same update cited end-of-session market cap figures for both exchanges.

What trading data showed during the session

The day’s trading range highlighted strong upward momentum from the opening levels. As per the figures shared, the stock opened at ₹175.30, versus a previous close of about ₹174.54 to ₹174.5. During the session, the share price moved between ₹174.51 and ₹191.99.

One data set in the snapshot reported an average price for the day of ₹183.25, while another reported an average traded price of ₹184.68. Either way, the move represented a sharp intraday rise, with the stock ending close to the day’s high.

Market capitalisation crosses ₹10,000 crore

PTI’s May 14 dispatch said Diamond Power Infrastructure rallied 10% and took its market valuation above ₹10,000 crore. It also provided exchange-wise market capitalisation numbers at the end of the session.

Alongside market cap, the snapshot also listed enterprise value. These valuation markers matter because they shape how investors interpret the stock’s move, especially when the rally is driven by expectations of future business inflows.

Why the stock was in focus: orders and sector tailwinds

The PTI report described the company as a key beneficiary of Adani Group orders. Separately, the provided text also noted that the company is “backed by the Adani family’s extended circle,” framing the market’s interest around relationships that could influence order flow.

Diamond Power Infrastructure operates in manufacturing of conductors, cables, and transmission towers. That positioning places it in the broader power transmission and distribution supply chain, where large projects can create surges in demand for equipment and EPC-linked supplies.

Performance: mixed return snapshots, strong recent momentum

The market snapshot stated that the share price had increased by 27.4% over the past six months and by 355.63% over the last year. A separate return table in the same input showed 1-week return of 13.00% and 1-year return of 102.39%.

These differences likely reflect varying calculation windows or data vendors, but the common point is that the stock has seen substantial appreciation over the periods cited. The stock’s strong momentum has also coincided with sharp changes in market cap over recent months.

Valuation metrics highlighted in the data

The provided valuation snapshot included a market cap figure of ₹10,057 crore at one point during May 14 and a P/E ratio of 87.20. It also listed a price-to-book (PB) ratio of -12.86 and book value of -13.56, along with ROCE of 3.49%.

In another part of the input, the stock was described as trading at a price-to-earnings multiple of 211.62 on the BSE. The presence of multiple P/E figures in the supplied text underlines how fast-moving price changes and differing reference periods can lead to different reported multiples.

Vision 2030: revenue target and FY25 base

Beyond the day’s price action, the most concrete strategic data point in the material is the company’s stated “Vision 2030”. The text says Diamond Power Infrastructure is aiming for a ₹10,000 crore revenue milestone by 2030.

The same passage notes this would be a nearly ninefold leap from a projected FY25 revenue of ₹1,115 crore. The annual report pathway described in the text includes volume expansion, technology leadership, and global exports as the levers for achieving that topline target.

Ownership and turnaround context cited in the snapshot

The input also characterised the company as a Vadodara-based cable manufacturer that had earlier been bankrupt and has since staged a turnaround. It stated that an acquisition in 2022 “marked a reset,” with “90% control” and a market cap of around ₹1,000 crore at the time.

Another governance-related point cited was promoter shareholding, described as over 84%. High promoter holding can support control stability, but it is also often watched for liquidity and free-float considerations.

Key numbers at a glance

Market impact: what investors are reacting to

The immediate market impact was the stock’s 10% jump and the milestone of crossing ₹10,000 crore in market capitalisation. For investors, this matters because it signals a re-rating phase where the market is pricing in future business visibility rather than only trailing financials.

At the same time, the data provided also shows that valuation metrics being cited vary meaningfully, with P/E ratios mentioned at 87.20 and 211.62. That combination of sharp price movement, high multiples, and strong one-year gains typically increases investor sensitivity to updates on order inflows, execution progress, and any disclosures linked to the company’s medium-term targets.

Conclusion

Diamond Power Infrastructure’s May 14 rally took the stock close to ₹192 and pushed market capitalisation above ₹10,000 crore, according to PTI’s exchange-wise figures. The move comes amid market focus on the company’s positioning in cables and transmission supplies and its stated Vision 2030 plan targeting ₹10,000 crore revenue, up from a projected ₹1,115 crore in FY25. Investors will likely continue tracking subsequent disclosures that clarify order wins, execution progress, and how the company plans to scale toward the 2030 target.
