    What Is the Buy-Side?

    Buy-side investing consists of financial institutions such as insurance firms, mutual funds, hedge funds, and pension funds that purchase securities to manage money and generate returns. These institutions look to buy underpriced assets with the potential for appreciation. Unlike the sell-side, which focuses on facilitating security sales, buy-side institutions directly invest with the goal of maximizing returns for their clients. 

    Opposite of the buy-side professional is the sell-side. Unlike the buy-side, sell-side efforts do not include making a direct investment. Instead, they assist the investing market with all activities related to the sale of securities to the buy-side, such as underwriting for initial public offerings (IPOs), providing clearing services, and generating research material and analysis.

    Together, the buy-side and sell-side form the core activities of financial markets.

    Key Takeaways

    • The buy-side consists of financial institutions like mutual funds and hedge funds that purchase securities to manage wealth.
    • Buy-side analysts work behind the scenes to develop investment strategies and perform in-depth research to boost client portfolios.
    • Unlike the buy-side, the sell-side focuses on facilitating the sale of securities and providing investment recommendations.
    • Large buy-side firms, such as BlackRock and Vanguard, have substantial market influence and can shape market trends.
    • Buy-side firms benefit from lower trading costs and access to extensive resources for real-time investment opportunities.

    Insights Into Buy-Side Investing

    A business involved in buy-side activities will purchase stocks, bonds, and other financial products based on the needs and strategy of their company's or client's portfolio. The buy-side activity takes place in many settings not limited to the financial institutions mentioned above. They also include trusts, equity funds, and high-net-worth individuals.

    The main goal of buy-side investing is to create value for a firm's clients. They do this by identifying and purchasing underpriced assets that they believe will appreciate over time. Because buy-side firms buy large blocks of securities, prestigious companies usually hold significant market power. These market titans are also closely watched by investors and the media.

    The value of BlackRock's assets under management (AUM) as of June 30, 2025. BlackRock is the largest investment manager in the world in terms of assets.

    Firms like BlackRock and Vanguard can significantly sway market prices as they make large-scale investments in single names. However, these investments are typically not disclosed in real-time and can be somewhat ghost-like for market traders. The SEC's 13F filing mandates buy-side managers to publicly disclose their holdings each quarter.

    Tracking and Learning From Buy-Side Investors

    The quarterly 13F filing is a useful tool for all investors to track top market investments. Warren Buffett and his firm, Berkshire Hathaway (BRK.A/B), are examples of how following buy-side investors can guide investment approaches. 

    Many investors study these large investors' holdings and changes to guide their own transactions. This data is available through several online resources.

    Advantages of Buy-Side Investing

    Buy-side investors enjoy several advantages over other traders. They can place large-lot transactions that minimize trading costs. They also have access to a very broad array of internal trading resources that helps them to analyze, identify, and act on investment opportunities in real-time.

    Important

    The buy-side analyst will also follow the regulations of the International Organization of Securities Commissions (IOSCO).

    Buy-side investors must disclose their holdings quarterly via 13F forms. Overall, it can generally be advantageous for buy-side analysts and investment firms to keep their investment research and watch lists proprietary. The high level of competition in the buy-side market and the nature of its business typically results in privacy around all trading ideas for the most optimal trading advantages.

    The Role and Responsibilities of a Buy-Side Analyst

    The buy-side analyst performs a pivotal role in the buy-side exchange. Buy-side analysts regularly work in non-brokerage firms including pension and mutual fund providers. These analysts provide recommendations based on research meant only for the use of these large fund providers. Individual investors may see sell-side recommendations, but buy-side work is behind the scenes at the big firms, and research strategies and the results of their analysis are kept private.

    Buy-side analysts conduct financial research and develop investment strategies, usually involving in-depth analysis and financial modeling. They may also talk directly to companies in which they have an investment interest. Buy-side analysts primarily are looking for companies that are a good fit for a portfolio’s strategy based on certain investing parameters and companies that will generate the highest returns over time.

    Due to their distinct roles, some firms separate buy-side and sell-side analysts with specific policies. At firms with both buy-side and sell-side analysts, a "Chinese Wall" can be constructed to separate the two departments, which usually entails procedures and security policies that prevent interactions between the two units.

    Buy-Side Investing Example

    John Smith works for a large investment bank investing his company's money in the stock market, utilizing a strategy he created himself. Over 10 years his strategy has done extremely well, outperforming the market by 10%. He decides to leave his firm and start his own investment management firm and invest money for high-net-worth individuals; in essence, Mr. Smith is creating a hedge fund.

    He spends time marketing his firm based on his strategy's returns over the past 10 years and is able to raise $10 million in capital from a variety of investors. He starts investing this capital and buys a variety of securities, including stocks, bonds, futures, and options, all aligning with his strategy. Mr. Smith's firm and his actions of buying these securities are an example of the buy-side.

    The Bottom Line

    The buy-side consists of investment institutions that actively purchase securities to manage money and generate returns for clients or their own accounts. Key players include mutual funds, hedge funds, and pension funds, whose investment decisions can significantly impact market prices.

    Unlike the sell-side, which facilitates security sales, the buy-side focuses on strategic asset acquisitions to maximize returns. As part of their strategy, buy-side investors look for underpriced or promising assets that align with their investment goals. They benefit from large-scale transactions, extensive resources, and a degree of confidentiality, which help maintain their market advantage.

    Understanding buy-side operations can guide investors in tracking influential market movements and enhancing their investment strategies.
