How does a little-known company turn into one of the world’s biggest stock market gainer in less than two years? That is the question many investors are asking as RRP Semiconductor’s share price defied gravity, even as its business numbers tell a very different story.

RRP Semiconductor has delivered a staggering 55,000% gain in just 20 months till December 17, making it one of the top-performing stock globally among companies with a market value above $1 billion. The rally has drawn massive attention on social media and trading forums, but it has also triggered serious concerns about valuation, fundamentals and risks.

A closer look at the company’s annual reports and business operations, as available on the stock exchanges, highlights key red flags.

A meteoric rise few can explain

Until recently, RRP Semiconductor was largely unknown to most market participants. Formerly called GD Trading & Agencies, the company rebranded itself and aligned its business description with India’s semiconductor ambitions.

Since then, its stock has gone on an extraordinary run, often hitting upper circuits for months at a stretch. As per exchange data, the stock remained locked at the upper circuit for around 149 consecutive trading sessions.

Business numbers raise uncomfortable questions

Despite its soaring share market value of over Rs 15,000 crore, the company’s operating performance remains weak. RRP Semiconductor posted negative revenue in the July–September 2025 quarter and reported a net loss of about Rs 7 crore. The company in the trailing 12 months recorded net sales of around Rs 14 crore while still ending in the negative territory.

Apart from all this, another factor adding to the surprise is the scale of its operations. According to the latest 45th annual report 2025 of RRP Semiconductors, the company has just two full-time employees.

Valuation do not match fundamentals

With these developments, RRP Semiconductor is trading at extreme valuation levels. As per reports, the stock has seen a price-to-book ratio running into four digits.

In simple terms, investors are paying extraordinarily high price for every rupee of assets or sales the company generates, something usually seen only in speculative bubbles. As a result, investors need to carefully consider all parameters and should not just go by the share price movement.

Stock under regulatory watch

The unusual price movement has not gone unnoticed. This sharp surge in the share price of the company has drawn attention from exchanges and regulators.

As per the latest update, the stock has been placed under surveillance due to unusual trading activity.

Furthermore, to control volatility, BSE has restricted the stock to trading only once a week. The exchange has also issued cautionary notes to investors following sharp price movements and market rumours, including reports linking the company to high-profile personalities, which the firm later denied.

Ownership structure adds to risk

Another area of concern is the company’s shareholding pattern. Public shareholders own nearly the entire company, while promoter holding stands at just about 1.27%, as per filings. Institutional investors are completely absent.

Semiconductor story still at an early stage

While RRP Semiconductor has stated that it changed its business focus in FY25 to align with semiconductor and digital chip activities, its current operations remain limited. The company earlier dealt mainly in electronic parts and has only recently indicated plans to expand into the semiconductor space.

The rally has turned RRP Semiconductor into a talking point across Dalal Street. However, the gap between stock price and business reality remains wide. Thin trading volumes, limited disclosures, regulatory scrutiny and weak financials are the key things investors need to know.
