ASX Weekly Roundup — 28 Sep to 02 Oct 2026
Weekly summary of the most significant bullish and bearish ASX announcements for the week of 28 Sep to 02 Oct 2026, focusing on shorted stocks.
Weekly ASX Market Roundup: Cybersecurity Traction, Mining Upsides, and Regulatory Headwinds (28 Sept – 02 Oct 2026)
This week’s ASX narrative was defined by a sharp divergence between operational execution and regulatory friction. While cybersecurity and infrastructure plays delivered tangible revenue upgrades that directly challenged bearish narratives, corporate governance failures in smaller caps dragged on overall sentiment. It wasn’t a blanket risk-on week; rather, it was a case of "show me the money" versus "watch out for the cliffs." For short sellers, the data suggests that while fundamental business improvements are providing cover for some positions, regulatory overhangs offer clear, high-probability setups for others.
Bullish Signals
ASX:CYB — AUCYBER LIMITED
AUCyber’s latest announcement is a textbook example of converting pipeline speculation into recognized revenue, a transition that typically commands a premium in the market. The company secured a managed security services contract with the University of New England, delivering over $600,000 in Annual Recurring Revenue (ARR) on a 12-month term. More significantly, they finalised a three-year deal worth $2.16 million, bringing their total new ARR from higher education contracts to approximately $1.34 million. This isn’t just noise; it’s a validation of their onshore Security Operations Centre (SOC) strategy, which leverages the SentinelOne platform to address AI-related security challenges. For short sellers, this is a thorny development. AUCyber currently sits at rank 133 with a short interest of 2.02%, suggesting that bears have been betting on the company’s inability to scale beyond niche contracts. However, the explicit mention of a $5.5 million tender pipeline for a major university introduces real upside risk. If successful, this could re-rate the stock’s valuation multiple from a project-based model to a recurring revenue model. The disclaimer that there is "no assurance" of success is standard, but the momentum is clearly shifting towards execution. Shorts here are likely hedging against the concentration risk in the higher education sector, but the recent wins in ISO 27001 and IRAP certifications provide a competitive moat that makes shorting the brand equity increasingly difficult. The market is rewarding the shift to ARR, and any failure to convert that $5.5 million pipeline could lead to a sharp repricing downside for skeptics.
ASX:SBM — ST BARBARA LIMITED
St Barbara has delivered a robust update on its 15-Mile Processing Hub Project in Nova Scotia, and the numbers speak for themselves. Ore reserves have increased by 17% to 1.4 million ounces (Moz), extending the mine life to 13 years without a corresponding increase in initial capital expenditure. The Life of Mine (LOM) gold production has risen by 203,000 ounces, supported by a low All-In Sustaining Cost (AISC) of US$1,098/oz. The financial uplift is substantial: the post-tax Net Present Value (NPV) has improved by 21% to A$1.7 billion at a gold price of US$3,000/oz. For short sellers, this is a defensive fortress. With a short percentage of 4.53%, bears are exposed to significant downside if gold prices remain elevated or rise, given the project’s high sensitivity to commodity prices. However, the low AISC provides a wide margin of safety, meaning even a modest pullback in gold prices won’t crush the project economics. The accelerated Feasibility Study timeline, targeting completion in March FY27, reduces execution uncertainty, while the funding plan—utilising A$427 million in cash reserves and proceeds from the New Simberi sale—means no immediate equity dilution is required. Short sellers may be betting on permitting delays or cost overruns, but the company’s assertion that the project scope remains within current regulatory submissions suggests these hurdles are manageable. The key risk for shorts here is the binary nature of mining developments; a Final Investment Decision (FID) in June FY27 could trigger a significant re-rating if the project proceeds as planned. Until then, the stock’s resilience against gold price volatility makes it a difficult short, especially with the strong balance sheet providing a cash buffer.
ASX:MP1 — MEGAPORT LIMITED
Megaport’s announcement is a masterclass in capital-efficient growth, securing approximately A$978.6 million in Total Contract Value (TCV) from three new AI infrastructure contracts. The strategic brilliance here lies in the prepayment structure: one customer provided A$281.5 million upfront, which covers the majority of the capital expenditure required to fulfil the contract. This de-risks the investment significantly, as Megaport isn’t having to fund the Capex from its own balance sheet. The company has upgraded its FY27 guidance, raising revenue expectations to $720M-$810M and increasing EBITDA margin guidance to 42-44%. For short sellers, this is a difficult environment to navigate. With a short percentage of 3.19%, bears are betting on the sustainability of these high margins and the concentration risk of relying on just three new contracts. However, the fact that compute ARR surged 90% since June 2026 to $201.4 million, with multiple GPU clusters already provisioned and billing, indicates that the growth story is real and accelerating. The 85% revenue concentration in North America is a geographic risk, but the high Net Revenue Retention (NRR) of 116% suggests strong customer stickiness. Shorts may be positioning for a slowdown in AI infrastructure spend, but the current billing execution and pre-funded nature of these contracts make a short squeeze plausible if guidance is further upgraded. The sheer scale of Capex required to replenish the GPU pool (US$252.0 million) is a operational commitment, but the prepayments mitigate the cash flow risk. As AI demand continues to outstrip supply, Megaport’s automated infrastructure platform is well-positioned, making short positions increasingly vulnerable to upward earnings surprises.
Bearish Signals
ASX:ABX — ABX GROUP LIMITED
ABx Group’s Share Purchase Plan (SPP) is a classic case of capital raising gone wrong, signalling weak organic demand for the equity. The company is raising $2 million at a discounted price of $0.031 per share, capped at 95% of the five-day VWAP, which immediately dilutes existing holders. The real issue, however, lies in the complex structure of the raise: 95% of the VWAP discount cap and free options attached to every two shares subscribed, plus 13.5 million Lead Manager Options. This creates a massive overhang of potential selling pressure, as the exercise price of $0.046 is significantly higher than the issue price, yet the volume of options is substantial. For short sellers, this is a vindication of the bear case. With a short interest of just 0.02%, shorts have been cautious, but this announcement validates the concerns about governance and value destruction. The reliance on a full underwriter by Alpine Capital suggests that without the underwriter, the raise might not have been fully subscribed. The requirement for shareholder approval adds friction, and the explicit warning that the securities are "highly speculative" highlights the precarious financial position. Shorts here are betting on the dilution and the potential for the options to be exercised and sold, creating sustained downward pressure. The premium pricing relative to the company’s fundamentals is unsustainable, and the market is likely to punish this aggressive dilution. The presence of a cleansing notice confirms that these new securities will be quoted, adding to the supply glut. For shorts, this is a clear signal to maintain or add to positions, as the upside is capped by the dilution while the downside is exacerbated by the loss of investor confidence.
ASX:DGR — DGR GLOBAL LIMITED
The Australian Takeovers Panel’s Declaration of Unacceptable Circumstances against DGR Global is a severe blow to corporate governance and market integrity. The declaration highlights that Managing Director Nicholas Mather and associates increased their aggregate voting power to 43.30% through a series of opaque transactions, breaching section 606 of the Corporations Act. The acquisitions were executed at a 52% premium to the last closing price, funded through hidden arrangements designed to obscure beneficial ownership. This is a regulatory nightmare, exposing the company to legal risks, potential penalties, and a loss of investor trust. For short sellers, this is a high-conviction setup. With a short interest of 0.01%, shorts have been positioned for a regulatory crackdown, and this declaration validates that thesis. The premium paid (52%) suggests that cash was diverted from strategic initiatives to placate specific shareholders, impacting liquidity. The involvement of the Managing Director in orchestrating these complex, opaque transactions raises red flags regarding management integrity. The Panel’s finding that Mather has substantial influence over Tenstar and that the actions created an unacceptable control effect suggests potential breaches of fiduciary duties. Shorts are likely betting on the remedial actions, which could include orders to dispose of shares or impose penalties, leading to significant share price volatility. The lack of transparency and the concealment of voting power indicate that the company’s internal controls are flawed. For shorts, this is a clear signal to maintain positions, as the regulatory overhang will likely suppress the stock price until the Panel determines the appropriate remedies. The risk of permanent damage to the company’s reputation and market standing is high, making this a difficult stock to long.
ASX:HRE — HEAVY RARE EARTHS LIMITED
Heavy Rare Earths Limited’s immediate suspension of its HREO security class from ASX quotation is a critical compliance failure that creates immediate liquidity risk. The suspension was issued under Listing Rule 17.3.4, pending compliance with Listing Rule 2.5, which typically relates to maintaining a minimum number of security holders. This suggests that the company has failed to meet distribution requirements, leading to an orderly market breakdown. For short sellers, this is a clear signal to avoid the stock, as the liquidity risk is extreme. With no short interest data available, shorts have likely already exited or are hedging heavily. The suspension prevents shareholders from trading their HREO securities, effectively locking in capital and removing the ability to raise equity through secondary markets. This can trigger cross-default clauses in debt facilities, exacerbating financial distress. The primary risk is permanent delisting if the company fails to demonstrate compliance within the allowed timeframe. If the company cannot restore the number of holders or rectify the distribution issue, the securities may be cancelled from quotation entirely. This would leave shareholders with illiquid, potentially worthless securities. The market outlook is highly uncertain and skewed towards negative outcomes, as regulatory suspensions are rarely resolved without significant corporate action. For shorts, the suspension itself is a negative event, but the lack of short interest suggests that the market has already priced in the risk. The key is to monitor the company’s efforts to comply with Listing Rule 2.5, as any failure could lead to a complete loss of value. The suspension is a stark reminder of the risks associated with small-cap, illiquid securities, and shorts should remain cautious until the compliance issues are resolved.
The Week Ahead
Next week, investors should closely monitor the Takeovers Panel’s response to the DGR Global declaration, as any remedial orders could trigger significant share price volatility. For short sellers, the ABx Group SPP dilution provides a clear catalyst for further downside, while the Megaport and AUCyber updates offer caution against adding short positions to fundamentally strong businesses. Keep an eye on gold prices, as any movement could impact the St Barbara NPV calculations and trigger a re-rating in the mining sector. Finally, the HRE suspension highlights the importance of monitoring ASX listing rule compliance, as small caps remain vulnerable to sudden liquidity evaporation.
