The Case for Long/Short Equity: Understanding Strategies, Approaches & Key Terms
Why Long/Short Equity Matters Now?
Australian advisors and their clients are increasingly asking a pointed question: in a market with no shortage of talented managers, why is consistent outperformance so elusive? The answer lies not in the quality of ideas, but in the structural constraints placed on how those ideas can be expressed.
Traditional long-only funds can only profit when a stock goes up. They are structurally limited in their ability to act on negative views—a manager who believes a stock is overvalued can, at best, hold less of it than the benchmark. This is a significant constraint, and it is one that long/short equity strategies are specifically designed to overcome.
What Is Long/Short Equity?
Long/short equity is a broad category of strategies that hold both long positions (stocks the manager expects to outperform) and short positions (stocks the manager expects to underperform). The short positions are typically funded by borrowing shares, selling them, and seeking to repurchase them later at a lower price. The resulting proceeds can then be reinvested into additional long positions.
This family of strategies spans a wide spectrum, and understanding where a fund sits on that spectrum matters for advisors.
The Spectrum of Strategies
At one end sits the market-neutral fund—constructed to have near-zero net exposure to the market. These funds aim to profit purely from the spread between their long and short books, regardless of market direction. They tend to have low beta, low correlation to equity indices, and are usually housed within alternatives allocations.
At the other end are concentrated long/short funds, which maintain meaningful net long exposure but use shorts to express high-conviction negative views. These can carry significant market sensitivity and behave more like active equity funds with extra tools.
In the middle—and of particular relevance to Australian investors—sits the active extension strategy. Sometimes called a 130/30 (or 135/35, 140/40), these funds maintain a 100% net long exposure to the market, typically benchmarked to an index like the ASX 200. They are permitted to short a defined percentage of the portfolio (say, 30%), with the proceeds reinvested into additional longs (hence “extension”). The result: the same market beta as a traditional equity fund, but a materially expanded opportunity set.
Why Australia Is Well Suited
The ASX 200 is a concentrated index, with the top 10 stocks representing a substantial share of total market capitalisation. In long-only portfolios, underweighting these large-cap names is difficult—there is a limit to how negative you can be on a stock that makes up 8% of the benchmark. Active extension strategies remove this constraint, allowing managers to express their full conviction without the distortions imposed by benchmark composition.
Additionally, Australian markets have historically shown good dispersion at the stock level—meaning individual companies diverge meaningfully in their performance. High dispersion is the environment in which skilled active managers can thrive, and in which short books can add the most value.
Key Takeaway
Long/short equity isn’t always about taking more risk—it’s about removing the structural handcuffs that prevent skilled managers from fully expressing their views. Active extension strategies generally offer the same market exposure as traditional equity funds while significantly expanding the opportunity set for alpha generation. For Australian portfolios navigating a concentrated index, this can be a meaningful advantage.
The structure makes sense on paper—but the proof is in the outcomes. In our next insight, Capturing Alpha, we take a clear-eyed look at the evidence and show how active extension strategies have the potential to strengthen risk-adjusted returns without changing the fundamentals of your equity allocation.
Appendix: Key Terms
- Net exposure: Longs minus shorts, expressed as a percentage of the portfolio. An active extension fund targets 100% net long—the same as a traditional equity fund (without taking into account the impact of gross exposure and leverage) — making it straightforward to categorise within existing asset allocation frameworks.
- Gross exposure: Longs plus shorts combined. A 130/30 fund has 160% gross exposure, meaning the total capital at work is greater than the portfolio’s NAV. This leverage is what enables the extended alpha opportunity.
- Tracking error: Measures how much a fund’s returns deviate from its benchmark. Active extension funds typically have moderate tracking error—higher than an index fund, but often comparable to, or only modestly above, a well-managed active long-only fund. The added tools do not necessarily mean dramatically more risk relative to benchmark.
- Alpha: The return generated above the benchmark on a risk-adjusted basis. Long/short strategies can generate alpha from both sides: by overweighting stocks that outperform and—as opposed to long only funds—by profiting from stocks that underperform.
- Short alpha: Often the most underappreciated source of value in these strategies. In Australian markets, where certain sectors have historically exhibited persistent overvaluation or structural decline, the ability to act on these views is genuinely additive.
