Most Overbought Stocks on The ASX: Violent Rallies Highlight Technical Extremes

A trio of billion-dollar Australian companies now ranks among the market’s most overbought stocks, each having staged dramatic comebacks after suffering sharp drawdowns earlier in the year, raising questions about whether momentum has run too far too fast.

Web Travel Group leads as the most overbought A$1bn+ market cap company on the index with an RSI of 79, following a 48.7% surge from its July 21st close. The WEB share price had been down 50% year-to-date before the reversal began. Guzman y Gomez shares are next up with an RSI of 76.09 after climbing 66.6% over four months, recovering from a 29.56% year-to-date decline. Computershare rounds out the top three at an RSI of 75.08, having rallied 51% from first-quarter lows to reach A$41.90, near the second-highest close in the company’s history after an 18.8% drawdown through March.

In technical analysis, RSI readings above 70 typically signal overbought conditions, suggesting prices may have risen too quickly relative to underlying fundamentals and could be vulnerable to near-term pullbacks. Each of these three stocks now sit well into that territory, as momentum flipped into reverse.

Fundamental Shifts Driving Momentum

The catalyst for WEB’s recent spike came in late July when management issued first-half FY27 guidance alongside a new share buyback programme, signalling confidence in trading momentum after what the company characterised as record revenue and EBITDA performance in the first half of FY26. The company had already completed a substantial A$150 million on-market buyback as part of its post-demerger capital management strategy.

Guzman y Gomez’s reversal stems from a strategic pivot that initially seemed like an admission of defeat but was embraced by markets as disciplined capital allocation. In May, the fast-casual Mexican restaurant chain announced it would exit the United States market entirely, closing its Chicago locations and abandoning what had been a capital-intensive expansion that burned cash. The US venture had been a key plank of the growth story pitched during GYG’s 2024 initial public offering, and the stock had become one of the most heavily shorted names on the ASX as sceptics questioned the valuation.

Rather than punishing the retreat, markets delivered a sharp relief rally, with some reports noting a single-day gain of around 20% on the announcement. The decision allowed management to refocus on the Australian core business, where the company maintains ambitions to reach more than 1,000 stores over the next two decades.

Computershare’s rally reflects both cyclical positioning and structural improvements. CPU’s earnings are significantly exposed to interest rates through the net income it generates on client cash balances and trust accounts and as central bank policy expectations shifted from aggressive tightening fears toward a more stable or modestly supportive outlook through the first half of 2026, Computershare benefited from both the rate environment and an improving pipeline of corporate actions such as initial public offerings, rights issues and merger activity that tend to flourish when volatility subsides.

The common thread linking these three overbought names is a violent sentiment shift from pessimism to enthusiasm, amplified by technical factors. Each stock was meaningfully down earlier in the year as markets questioned fundamental assumptions and volatility works in both directions. When each company delivered a catalyst that reframed the narrative, positioning caught up violently, with short covering playing a material role.

The risk for all three is that positive catalysts are now well-known and largely reflected in current prices. At these technical extremes, the marginal information risk has shifted to the downside. Any negative surprise versus recently elevated expectations could trigger sharp mean reversion, particularly if broader market conditions deteriorate or sector-specific headwinds emerge.

The dramatic reversals in Web Travel Group, Guzman y Gomez and Computershare illustrate how quickly momentum can shift when beaten-down stocks deliver positive catalysts, but with all three now trading at technical extremes, a pause for thought could well be a healthy sign if current direction of travel is to hold.
