What is long-short equity?

Long-short equity is an investment strategy that involves simultaneously taking long and short positions with the intent of controlling market exposure while still trying to generate positive returns for the investor. Long positions are taken in stocks that are expected to increase in value while short positions are taken in stocks expected to decline in value.

Long vs short positions:

• Long positions involve purchasing securities with the expectation that their price will increase over time. This is the ‘traditional’ way of investing.
• Short positions, on the other hand, involve borrowing securities (often through securities lending agreements) and selling them immediately with the expectation that their price will decrease. Investors taking short positions aim to buy the stocks back at a lower price in the future and capture the price difference.

Long-short equity strategies combine both long and short positions to minimize market exposure. The goal is to be less susceptible to losses during market declines while still allowing for potential gains during market upturns.

These strategies are commonly used by hedge funds, many of which apply a market-neutral approach that balances the dollar amounts of both long and short positions. The aim is to reduce overall risk and generate returns regardless of market direction.

How does long-short equity investing work?

Long-short equity investing involves building a portfolio that combines long and short positions to potentially profit from both rising and falling stock prices. Long positions are taken in stocks expected to appreciate in value and short positions are taken in stocks expected to decline in value. The aim is to profit from upside potential while mitigating downside risk.

The long-short equity investing process involves continuously identifying, establishing, tracking, and closing positions in securities. First, in-depth research is required to identify potential securities. Investors will analyze securities, considering factors such as financial performance, industry trends, and market conditions, to determine which stocks are potentially undervalued or overpriced. Once they’ve identified suitable stocks, investors will buy shares expected to increase in value and borrow shares expected to decrease in value, selling them immediately.

They will then continuously monitor and adjust their positions as needed. To do this, investors must keep an eye on market trends, assess company performance, and evaluate each position’s risk-reward profile. Investors will close their positions when their investment thesis has played out or when it’s time to rebalance their portfolios. To do this, they’ll sell their long-position securities and buy back short-position securities to return to the broker.

Long-short equity strategies can vary – some focus on specific sectors (e.g. retail or technology) while others target geographic regions (e.g. advanced economies vs emerging markets). Many funds balance long and short positions equally, while others adopt a long bias (for example, 130/30 – with 130% long exposure and 30% short exposure). Certain funds will employ a short bias, however this is generally less common.

Ultimately, long-short equity strategies aim to generate returns regardless of market direction while also managing risk through diversification and hedging. The idea is to deliver equity-like returns with less volatility than the equities market. Long-short equity strategies are mostly used by institutional investors such as hedge funds or mutual funds.

What are the potential benefits of long-short equity strategies?

Below are some reasons why a hedge fund or mutual fund might choose to adopt long-short equity strategies:

Mitigate systemic risk

Long-short positions can offer a way to hedge against market-wide risks by reducing some of the portfolio’s sensitivity to market movements (beta). By combining both long and short positions, these strategies aim to offset losses during market downturns. For example, long positions stand to profit from rising markets while short positions can provide a cushion against losses if the market declines.

Potential for higher returns

Long-short strategies also have the potential to generate higher returns by allowing investors to profit from both upward and downward price movements. By taking both long and short positions, investors can increase their potential for returns compared to traditional long-only investment strategies. Investors sould consider that long-short strategies may come with costs that can offset some higher returns. 

Achieve market neutrality

Some investors adopt long-short equity strategies to build market-neutral positions. This involves investing equal amounts into both long and short positions. The aim of market neutrality is to insulate portfolios from broader market movements by taking equal losses and gains as the market moves up and down.

Improve diversification

By combining positions in both underperforming and overperforming securities, investors can build a more diversified portfolio. Effective diversification will depend on the correlation between long and short postitions. This can minimize market exposure and mitigate the impact of market downturns, reducing an investment’s overall risk and volatility.

What are the potential risks of long-short equity strategies?

While long-short equity strategies have the potential to generate higher returns, they also come with certain risks that must be carefully considered. These include:

Amplified losses

Long-short equity funds rely on investors to successfully predict a stock’s expected performance. If market predictions are incorrect – for example, if a stock held in a long position underperforms or a shorted stock unexpectedly increases in value – the portfolio can suffer significant losses. This risk is greater during volatile or unpredictable market conditions.

Short-sale risks

Short positions are inherently riskier than long positions. The potential losses on a short sale are theoretically unlimited as a stock’s price can continue to rise with no cap on its growth. Being able to manage unsuccessful short positions requires active oversight which can add complexity and stress to portfolio management. 

Complexity and costs

Long-short equity strategies are more complex than traditional long-only investments. Balancing both long and short positions requires careful analysis, constant monitoring, and precise implementation. These strategies can also involve higher trading costs and expense ratios which can erode returns if not properly accounted for.

Market & company-specific risks

Market fluctuations or unexpected company-specific events can negatively impact both long and short positions. For example, a company in a short position might release positive earnings which leads to losses for the investor. Imperfect or ineffective hedging  can leave the fund exposed to basis risk..

How is the long-short equity strategy used as a hedge against risk?

Long-short equity strategies are widely used to hedge against market risk. Market risk stems from broad economic events, such as global recessions or macroeconomic shocks, that impact the entire stock market.

A long-short equity fund aims to mitigate this risk by combining long positions to profit from rising stocks, with short positions to profit from falling stocks. With this combined approach, funds can potentially minimize their chance of being fully exposed to adverse market movements. This can help maintain portfolio stability even during economic downturns or unexpected ‘black swan’ events.

Mitigating this market risk can allow funds to concentrate more on stock selection rather than macroeconomic factors. Although it’s inevitable that some losses will be incurred, the goal is to offset or exceed these losses through gains made from successful positions. This can provide more consistent returns with reduced volatility overall.

What are some common long-short equity strategies?

There are various approaches to adopting a long-short equity strategy, depending on a fund’s risk tolerance and investment objectives. Below are some common long-short equity strategies:

130/30 strategy (long bias strategy)

The 130/30 strategy involves allocating 130% of a portfolio to long positions and 30% to short positions. This strategy has the potential to increase returns; however it also comes with increased risks due to leverage and market volatility. Adopting a 130/30 strategy requires strong risk management and a commitment to long-term investment.

Market-neutral strategy

Market-neutral strategies involve balancing the total value of long and short positions to reach a net market exposure of zero. This can provide a hedge against market fluctuations and allow funds to focus on individual stock selection instead.

Equity market-neutral funds have the potential to generate stable returns, but require careful balancing of long and short positions, which can be complex. While they offer lower market risk, they also tend to come with lower upside potential.

Pair trading

Pair trading involves finding two securities considered to have a strong correlation but are trading at a mismatched price. Based on their historical price relationship, investors take a long position in a security considered undervalued and a short position in a security considered overvalued. The strategy aims to generate returns from the expected mean reversion, where stock prices eventually return to their historical norms.

When executed well, pair trading can offer consistent returns with lower market risk. However, strong statistical analysis skills are required to identify suitable pairs, and the securities should have sufficient liquidity for the trades to be executed well.

Sector-specific strategy

Sector-specific strategies focus on investing within a particular industry, such as technology, retail, or energy. Investors should have deep expertise in the chosen sector to capitalize on trends and opportunities to outperform the market. However, sector-specific strategies have limited diversification which can increase risk exposure.

Geographic-specific strategy

A geographic-specific strategy targets specific regions or markets, such as Europe or emerging markets. This strategy allows investors to diversify their portfolios and potentially capitalize on local market dynamics, however it also increases the risk of currency fluctuations and political instability.
