Learn about the basics of long-short equity investing, from its core concepts and the common strategies, as well as the benefits and risks involved.
Long-short equity is an investment strategy that originated in the early 20th century, along with the rise of hedge funds, as investors leverage this technique to reduce market risk and capitalize on individual stock movements. With the advancements in financial theory and computing technology, long-short equity gained significant traction between the 1970s and 1980s. This was when investors began to leverage statistical analysis and algorithms to identify opportunities with greater profit.
While investors continually seek to refine their strategies and adapt to changing market conditions, long-short equity remains a relevant and dynamic investment approach up to this date. Thus, this article will delve into the core concepts of long-short equity, exploring how it works, as well as the benefits and risks of long-short equity funds.

Long-short equity is an investment strategy that involves simultaneously taking long positions when buying securities and short positions while selling securities.
Long position refers to the traditional way of investing, where investors buy securities (like stocks or bonds) with the expectation that their value will increase over time. In contrast, a short position is where you borrow securities from a broker and sell them immediately, as their value is expected to go down, allowing investors to buy them back at a lower price in the future.
With this, long-short strategies have a lower sensitivity to equity market movements when compared to their long-only counterparts, as measured by their beta, volatility, and drawdowns. This means that they are less likely to experience significant losses during market declines, while still capturing potential gains during market upturns.
By combining long and short positions in a long-short equity strategy, investors aim to profit from both rising and falling markets. This can reduce the overall risk and potentially generate returns regardless of market direction.
Long-short equity investing involves a systematic process of identifying, establishing, monitoring, and closing positions in securities.
To identify potential securities, investors will carefully research and analyze various securities, picking out potential candidates for both long and short positions. Factors such as financial performance, industry trends, market valuations, and expected catalysts will be considered when making this decision.
Once the potential securities are identified, investors will establish their positions. If the investors believe the securities will appreciate in value, they will purchase them. If the securities’ value is expected to decline, the investors will borrow them from a broker and sell them immediately.
Then, investors will continuously monitor the performance of their positions and make adjustments as needed. This may involve tracking market trends, evaluating the performances of relevant companies, and assessing the risk-reward profile of each position.
Investors will close their positions when they believe their investment thesis has played out. Some investors will also close their positions when they need to rebalance their portfolios. At this stage, investors will sell their long-position securities to realize profits or losses. The short-position securities will also be bought back and returned to the broker.
In turn, investors require reliable and accurate data for rigorous data analysis to make informed decisions in each step of the long-short equity process. Such information can be obtained from trusted providers offering high-quality datasets.

Long-short equity strategies encompass a variety of approaches, each with its own unique characteristics. By understanding these various strategies, investors can select the approach that best aligns with their risk tolerance, investment horizon, and desired returns.
In a 130/30 strategy, investors allocate a significantly higher percentage of capital to long positions than to short positions. Typically, the ratio is 130% to 30%, hence the name.
While the increased long positions could potentially amplify returns, they also increase risks due to leverage and market volatility. Thus, this strategy is more suitable for investors with a high risk tolerance and positive market outlook, as it requires careful risk management and a long-term investment horizon.
Market-neutral strategies aim to have a net exposure of zero to the overall market. This means that the total value of the long and short positions is roughly equal, effectively hedging against market fluctuations.
By focusing on relative value analysis and individual stock selection, market-neutral funds can generate more stable returns, but they may be harder to manage due to the complexity of balancing long and short positions. Market-neutral funds could also underperform in strong uptrends when compared to more aggressive strategies. So, investors seeking to take this approach should be prepared for the lower upside potential in return for the lower market risk.
Pair trading is a quantitative trading strategy that involves identifying two securities that are expected to have a strong correlation but are currently trading at a mismatched price. Investors will compare the current prices of the two securities to their historical relationship. If one security trades at a significant premium or discount to the other, it may be considered mispriced.
By taking a long position in the undervalued security and a short position in the overvalued security, investors aim to profit from the expected mean reversion of the price difference. This could generate consistent returns with reduced market risk. However, it is important to note that investors need to have strong statistical skills to identify correlated pairs and the securities selected for pair trading should also have sufficient liquidity to ensure smooth execution of trades.
Sector-specific strategies focus on investments within a particular industry or sector, such as technology, healthcare, or financials, allowing investors to capitalize on sector-specific trends.
This strategy often requires the employment of investment professionals with deep knowledge and understanding of their target sector. By leveraging their expertise, they can gain a competitive edge to outperform the market. Yet, concentrating investments within a single sector can also limit diversification and increase risk. This is why investors should carefully evaluate the long-term prospects of the chosen sector and its sensitivity to economic factors before implementing sector-specific funds.
Geographic-specific strategies target specific markets or regions, such as Europe, the United States, or other emerging markets. This requires close monitoring of local markets and economic conditions in the targeted region.
By implementing this strategy, investors have the opportunity to diversify their portfolios and capitalize on local market opportunities. However, geographic-specific strategies are often susceptible to risks associated with currency fluctuations and political instability, so investors should carefully consider these factors when taking this approach.

Unlike traditional long-only strategies, long-short equity strategies involve both long and short positions, creating a more diversified portfolio. By combining positions in securities expected to outperform the market with those expected to underperform, investors can potentially reduce their overall market exposure and mitigate the impact of market downturns. In turn, this lowers the overall risks and volatility of the investment.
Furthermore, long-short equity hedge funds also have the potential for higher returns, as investors capitalize on both rising and falling markets. This allows investors to capture profits from both upward and downward price movements, which is generally hard to achieve through long-only investments.
While long-short strategies have the potential for greater gains, they might also amplify losses when not implemented successfully. This risk is especially prevalent when there are disadvantageous market fluctuations, such as short-sale depreciation and individual company-specific factors, which could impact the performance of both long and short positions.
In addition, long-short equity strategies have higher complexity than traditional mutual funds, as investors have to balance securities in distinct positions. Due to this increased complexity and trading costs involved, long-short equity funds also have higher expense ratios, which can impact overall returns if not implemented carefully.
With these complicated risks and considerations, it’s essential to leverage reliable resources and accurate data which can help to ensure the precision of long-short strategies.
