It was a tough Monday for the broader market. The S&P/ASX 200 Index was down 0.5% to 9,038.2 points in afternoon trade. But four ASX-listed companies told a completely different story. Each one released results or a key update. Each one surged between 12% and 17% in a single session.

That is the power of quarterly reports. In one morning, they can separate a company from the broader market entirely. The numbers, the guidance and the narrative around results all feed directly into investor decisions. Understanding how that process works is increasingly important for anyone watching ASX-listed stocks.
Quarterly Reports in Action: Four ASX Stocks That Surged
Here is what each Company reported and how the market responded:
- Electro Optic Systems Holdings (ASX: EOS) surged 17% to $8.57 after releasing its FY2025 results. Revenue from continuing operations came in at $128.5 million, down 27% year on year. However, its unconditional order book stood at $459 million as on 31 December 2025, up 238% from $136 million a year earlier. Management flagged it aims to realise 40% to 50% of that order book during 2026
- Nuix Ltd (ASX: NXL) rose 16% to $1.58 after its half-year results showed annualised contract value growth of 8.4% to $234.4 million. Its Nuix Neo offering delivered ACV growth of 148% year on year to $46.8 million, now representing 20% of total ACV
- Reece Ltd (ASX: REH) climbed 16% to $16.15 after reporting a 6% increase in revenue to $4,648 million. Net profit after tax declined 20% to $144 million, but this was better than Morgans had forecast, which was a 22.9% decline to $139.5 million
- Clarity Pharmaceuticals (ASX: CU6) gained 12% to $3.92 after announcing that another patient in its SECuRE Phase II trial achieved undetectable disease following treatment
Each of these reactions tells a story. And each one illustrates a different dimension of how quarterly reports move share prices.
Stock Price Reaction Depends on Expectations, Not Just Numbers
The Reece result is a useful example here. Net profit fell 20%. That is not a headline that typically sends a stock up 16%. But because the actual result was better than what analysts had modelled, investors responded positively. The stock price reaction had little to do with the absolute number and everything to do with the gap between expectation and reality.

This is one of the most important concepts in quarterly earnings analysis. When earnings beat expectations, buying pressure tends to follow. When they miss, selling pressure typically arrives. And when the market has already priced in strong performance, even a solid result can sometimes cause a pullback.
The EOS result reinforces this further. Revenue fell sharply, yet the stock surged because the forward-looking order book told a compelling story about what comes next.
Quarterly Earnings Analysis Goes Beyond Revenue and Profit
The EOS result is a textbook case of guidance driving the stock price reaction more than current-period numbers. Revenue was down 27%. On its own, that is a weak headline. But an order book up 238% year on year reframed the entire result. Investors were not buying what EOS earned in 2025. They were buying what EOS signalled about 2026.

This is consistent with how quarterly earnings analysis works in practice. Management commentary, forward guidance and strategic updates frequently have a larger impact than the current quarter result.
Nuix interim CEO John Ruthven addressed the AI disruption concern directly in his commentary, saying the Company is well-positioned through its BYO AI framework. That kind of forward-looking narrative can matter as much as the ACV numbers sitting behind it.
Quarterly Reports Create Short-Term Volatility and Long-Term Signals
For short-term traders, quarterly reports are a source of opportunity. Sharp single-session moves like those seen today across EOS, Nuix, Reece and Clarity create clear entry and exit scenarios. But managing risk around results is equally important. Gaps can move against a position quickly if the result lands differently from expectations.

For long-term investors, quarterly earnings analysis serves a different purpose. It is about building a picture of financial health over time. Revenue growth, profit margin trends, debt levels and order book momentum all contribute to that picture. A single quarter rarely defines a thesis. But consistent patterns across multiple quarterly reports often do.
Industry Outlook
Quarterly reports remain one of the most reliable catalysts for share price movement in equity markets globally. As AI-driven analytics tools become more accessible to retail investors, the speed at which markets process and price earnings results is accelerating.
For ASX-listed Companies, transparent and well-communicated results increasingly separate those that attract long-term capital from those that face persistent selling pressure after each reporting season.
