This Week’s Best Performing ASX Stocks – 31st October

The Australian sharemarket concluded the week on a bearish note, with the S&P/ASX 200 Index shedding 1.94% over the last five days, reflecting a broad decline driven by weakness in the energy, technology, and financial sectors, coupled with anxieties surrounding critical minerals. The index closed Friday down 0.8% at 8,995.3, relinquishing some of its gains after briefly surpassing 9,100 earlier in the week.

In this article we look at three ASX stocks that have made significant gains in the last week. We have focused on mid-sized companies and larger here – companies with a market cap of at least 1 billion AUD.

This Week on the ASX

The technology sector bore the brunt of selling pressure, with Life360 Inc. experiencing a significant downturn, plummeting 8% to $45.54. This marked the company’s steepest single-day loss since April, contributing to the overall negative sentiment surrounding tech stocks. The energy sector also faced headwinds, further exacerbating the index’s decline as investors reacted to global energy market dynamics.

Commodity-related companies presented a mixed picture. Gold miners, buoyed by the precious metal reaching a record high of $US4,378.69, saw gains. Newmont Corporation shares ascended 2.9% to $149.96, while Northern Star Resources Limited advanced 2.3% to $26.05. Conversely, companies involved in copper, lithium, and rare earths faced downward pressure. Shares in Lynas Rare Earths Limited plummeted 5.7%, and Paladin Energy Limited declined 6.8%, as markets exhibited skepticism ahead of Prime Minister Anthony Albanese’s discussions with the US President concerning critical minerals stockpiling strategy. Iluka Resources Limited also experienced a setback, dropping 2.4% after withdrawing its sales forecast due to issues with a key customer. Among the major players, BHP Group Limited edged down 0.4%, contrasting with a 1.3% rise for Rio Tinto Limited.

The financial sector also felt the strain, with QBE Insurance Group Limited suffering a notable 9.3% drop. Major banks, including National Australia Bank Limited and Westpac Banking Corporation, also experienced declines, each falling 0.8%, compounding the negative pressure on the broader market.

The Reserve Bank of Australia (RBA) has adopted a cautious approach, signaling no immediate reduction in interest rates due to persistent inflation in the services sector and a stable employment landscape. The central bank emphasized that future policy decisions will hinge on incoming economic data. Currently, markets are divided on the likelihood of a rate cut in November, awaiting forthcoming consumer price data to provide further clarity.

Silex Systems (SLX) +20.23%

Silex Systems (SLX.AX) has emerged as a top performer on the ASX, with its stock price surging 20.23% over the past week and an impressive 103.14% overall. This significant uptrend is fueled by advancements in its proprietary laser-based uranium enrichment technology and its potential to reshape the nuclear fuel industry.

The recent surge in Silex Systems’ stock is largely attributed to a third-party validation of its uranium enrichment technology by a Fortune 1000 technology provider. The assessment confirmed that Global Laser Enrichment (GLE), the exclusive licensee of Silex’s technology, has achieved commercial-scale readiness. Following the announcement, Silex’s shares jumped 22% to A$9.44, reaching levels not seen since October 2007.

GLE’s successful completion of large-scale demonstration testing of Silex’s uranium enrichment technology in North Carolina has further bolstered investor confidence. The company’s achievement of Technology Readiness Level 6 (TRL-6) is a crucial milestone toward commercial deployment. GLE has also submitted a bid for funding from the U.S. Department of Energy to aid in rebuilding the country’s nuclear fuel infrastructure, highlighting the growing focus on nuclear energy independence and Silex’s role in secure energy supply chains.

Despite a reported financial downturn for FY 2025, including a 28.8% decrease in cash and equivalents and an 87.2% increase in net loss, Silex Systems’ market capitalization has seen substantial growth. As of October 24, 2025, the company’s market cap stood at A$2.55 billion, reflecting a 141.27% increase over the past year. The markets appear to be focused on the future potential of Silex’s technology rather than its current financial performance.

Director Michael Goldsworthy’s acquisition of 208,600 Performance Rights as part of FY2026 incentives further aligns executive interests with the company’s long-term goals. This move, approved by shareholders at the 2025 AGM, is viewed as a positive sign for the company’s operational focus and its commitment to stakeholder value.

Analysts suggest that Silex Systems’ advancements in uranium enrichment technology position it favorably in the global shift toward secure energy supply chains. The company’s ability to achieve commercial-scale readiness and its potential to secure funding from the U.S. Department of Energy are key factors driving positive market sentiment.

Domino’s Pizza Enterprises (DMP) +19.35%

Domino’s Pizza Enterprises (DMP.AX) has experienced a volatile week, marked by a significant 19.35% gain driven by takeover speculation, despite the company’s recent financial challenges and strategic adjustments. The stock’s movement reflects a market grappling with both potential opportunities and underlying concerns surrounding the pizza chain’s performance.

The primary catalyst for the recent surge was a report on October 28, 2025, suggesting that Bain Capital was considering a A$4 billion acquisition of Domino’s. This news propelled the stock price by 23% to A$19.00. However, Domino’s swiftly denied these reports, stating that no such proposal had been received, leading to a retraction of most of the gains and settling at A$16.53. This rapid ascent and subsequent decline underscore the sensitivity of the stock to takeover rumors, even in the absence of concrete offers, and shows that the market is reactive to potential strategic shifts that could unlock value.

Beyond the takeover speculation, Domino’s has been actively implementing strategic initiatives to address recent financial headwinds. The company reported a statutory net loss of A$3.7 million for the fiscal year, its first annual loss in two decades, alongside a 2.8% decrease in net profit after tax to A$116.9 million and a 4.6% drop in earnings before interest and tax to A$198.1 million. In response, Domino’s unveiled a “Recipe for Growth” strategy, prioritizing efficiency programs and debt reduction to bolster its financial standing. This plan aims to streamline operations and enhance profitability in a challenging market environment.

Further illustrating its strategic recalibration, Domino’s announced in February 2025 the closure of 205 underperforming stores, including 172 in Japan. This decision was projected to yield annual savings of approximately A$15.5 million and boost operating earnings by A$10-12 million. The market reacted positively to this news, with the stock experiencing an intraday surge of 23.8%, reaching A$36.68. These closures reflect a focused effort to concentrate resources on more profitable markets and improve overall efficiency.

Adding another layer to the company’s strategic efforts, Domino’s issued 18,442 unquoted equity securities in late September 2025 as part of a new employee incentive program. This initiative aims to motivate and retain key talent by aligning employee interests with the company’s long-term success. Such programs can be instrumental in driving operational improvements and fostering a more engaged workforce.

However, not all news has been positive. In February 2025, Domino’s reported a slowdown in same-store sales growth, with a 1.5% increase in the first seven weeks of the second half, down from 4.3% during the Lunar New Year period. This slowdown, combined with a first-half profit miss, led to an 11% drop in the stock price, reaching its lowest level since mid-January. This indicates that sustaining sales momentum remains a key challenge for the company.

Price Targets

The recent market activity surrounding DMP.AX highlights a complex interplay of factors influencing investor sentiment. While the takeover speculation injected a short-term boost, the underlying strategic initiatives and financial performance will likely be the key determinants of the stock’s long-term trajectory. The market will be closely watching how effectively Domino’s executes its “Recipe for Growth” strategy and navigates the challenges of a slowing sales environment. Whether the stock can maintain its recent gains will depend on the company’s ability to deliver tangible improvements in profitability and demonstrate sustainable growth.

FireFly Metals (FFM) +18.01%

FireFly Metals Ltd (ASX: FFM) has emerged as a star performer on the ASX, fueled by outstanding drilling results at its Green Bay Copper-Gold Project and subsequent positive analyst ratings. The company’s share price has experienced a substantial surge, gaining 18.01% over the past week and an impressive 113.48% overall.

The markets reacted positively to the news of exceptional high-grade copper-gold intersections at the Green Bay project, located in Canada. Drilling revealed a significant 800-metre-long high-grade core, featuring notable intersections such as 43.6 meters at 7.6% copper equivalent (CuEq) and 44.5 meters at 3.7% CuEq. These results indicate substantial resource expansion potential, a key driver of the recent bullish sentiment.

Adding to the positive momentum, two independent analysts issued ‘Buy’ ratings for FireFly Metals following the release of the drilling results. These endorsements reflect confidence in the company’s growth prospects and the inherent value of the Green Bay project, further solidifying investor confidence. The ‘Buy’ ratings have signaled to the markets that FireFly Metals is undervalued, given the potential upside from the Green Bay project.

FireFly Metals’ strong financial position has also played a crucial role in its recent success. In June 2025, the company secured firm commitments to raise approximately AU$95 million through an equity raising. These funds are specifically allocated to advance the Green Bay project, supporting resource expansion and pre-construction activities. This financial stability reassures investors of the company’s ability to execute its strategic plans.

Further demonstrating investor confidence, FireFly Metals’ Share Purchase Plan (SPP) was significantly oversubscribed. In July 2025, the company doubled its SPP to AU$10 million in response to strong demand from shareholders. The SPP received applications totaling approximately AU$28.2 million, indicating robust investor interest and a belief in the company’s future direction.

The company’s share price has seen considerable appreciation, with a 31.8% increase over the past month and a 98.9% rise year-to-date. This upward trajectory is attributed to the company’s successful exploration milestones and the potential for unlocking deeper value within the Green Bay project. The markets have responded favorably to these developments, driving the recent positive sentiment.

Analysts have noted that FireFly Metals’ exploration milestones are a key factor in unlocking deeper asset value, which further contributes to positive investor sentiment. This recent progress has been well-received by the markets, with the company’s share price reflecting the increased optimism.

Looking ahead, the focus will likely remain on the continued development of the Green Bay project. Successful execution of the planned resource expansion and pre-construction activities will be crucial in maintaining the positive momentum. The company’s ability to deliver on its promises and further demonstrate the economic viability of the Green Bay project will be critical in sustaining investor confidence.
