Viva Energy Shares Rally 38% in July, New High Comes With Most Overbought Crown

Viva Energy shares (ASX: VEA) rocketed to a fresh 52-week high of A$2.87 to close out July, capping a remarkable 38.35% monthly gain that crowned the company as the most overbought name on the ASX.

The explosive rally, driven by a substantial first-half earnings beat, has pushed the stock’s RSI above 81, raising questions about whether the momentum can continue or whether a technical correction looms as August trading begins.

Why Are Viva Energy Shares Up?

The catalyst for the July breakout above resistance came on 28 July, when Viva Energy released its 1H26 trading update. The company guided Group EBITDA on a replacement cost basis at approximately A$770 million to A$780 million for the half, representing a beat of roughly 9% above consensus estimates of around A$708 million. More strikingly, the figure more than doubled the A$305 million recorded in the prior corresponding period, with the uplift driven overwhelmingly by a sharp improvement in refining margins at the company’s sole remaining Australian refinery in Geelong.

Markets responded immediately and decisively. Viva Energy shares bounced 8.61% on the day of the announcement, and accelerated through the final trading sessions of July as momentum buyers and trend-following strategies piled in, propelling the stock to its A$2.87 high.

The earnings surprise validated a structural thesis that had been building quietly among value-oriented funds earlier in the year.

In early July, global asset manager State Street Corporation disclosed that it had increased its holding in Viva Energy to approximately 5.03% of shares on issue, becoming a substantial holder. The move was interpreted by markets as institutional endorsement of the company’s long-term investment case, particularly given research at the time suggesting the stock could be undervalued by 20% to 25%. With Vitol, the company’s largest shareholder and a global energy trading house, retaining a 29.9% stake, the register has become increasingly weighted toward sophisticated, longer-term holders.

The fundamental driver behind the earnings beat was unambiguous: refining margins have more than doubled compared to the prior year, reflecting a combination of global refining capacity tightness, regional supply-demand dynamics, and geopolitical factors that have supported crack spreads.

Viva Energy’s Geelong refinery, one of only two remaining oil refineries in Australia, has benefited from government support measures introduced in recent years to underpin domestic fuel security. The company also highlighted a meaningful improvement in its balance sheet during the first half, with stronger cash generation reducing leverage and creating optionality for enhanced capital management, including potential dividend increases or share buybacks.

What Next?

The immediate focus for markets now shifts to Viva Energy’s formal half-year 2026 results, scheduled for release on 25 August 2026. The bar has been set high: with sentiment now bullish and positioning more crowded, markets will likely demand a “beat and raise” outcome to justify current valuations and sustain the upward trajectory.

Bulls argue that the company’s upgraded earnings base, improved balance sheet, and institutional support provide a solid foundation for further gains, particularly if the formal results confirm or exceed the preliminary guidance. Momentum traders point to the alignment of all major moving averages in buy mode and the stock’s leadership position on the ASX 200 as evidence that the trend remains intact.

Bears counter that much of the earnings strength is cyclical rather than structural, tied to refining margins that are historically volatile and prone to mean reversion. Any indication in the August results that crack spreads have begun to soften, or cautious commentary about the second-half outlook, could trigger sharp profit-taking from the elevated technical levels. The overbought RSI reading and the magnitude of July’s gain increase the statistical probability of at least a near-term pullback, even in the absence of negative news.

With a huge month behind Viva Energy shares, momentum now becomes the question. Having traded almost level YTD leading into July, the stock now begins August as the most technically overbought name on Aussie markets. As the share price trades at levels not seen since 2024, some cooling could be expected, yet with oil prices continuing to look supportive into the weekend, there remains plenty for bulls and bears to debate.
