A buy-side analyst researches securities for the institution that employs them, such as a mutual fund, pension fund, hedge fund or insurer. The research helps that institution decide what to buy, hold or sell with its own or its clients’ money. A sell-side analyst works for an investment bank or brokerage and publishes research, earnings estimates, price targets and ratings for the firm’s clients. Both roles analyze companies. The difference is who uses the work and how the analyst is paid. Buy-side research stays inside the firm and is judged by portfolio returns. Sell-side research goes out to clients and is valued for the information, access and trading business it brings in.

Who Buy-Side and Sell-Side Analysts Work For

The names come from the two sides of a securities transaction. The buy side is the money that buys securities: asset managers, mutual funds, hedge funds, pension funds, insurance companies, endowments and private equity firms. The sell side is the set of firms that create, sell and trade those securities and earn fees and commissions doing it: investment banks, broker-dealers and their research departments.

Applied to an investment bank, the sell side covers the bank’s underwriting, sales, trading and research businesses. They help companies issue securities and help investors trade them. A bank can also run an asset management arm. That arm sits on the buy side even though it shares a parent company with the bank’s research desk.

What a Buy-Side Research Analyst Does

A buy-side research analyst’s job is to find investments that will help the fund beat its benchmark and to flag the ones that could hurt it. The work runs roughly in this order:

1. Generate or screen ideas. Ideas come from the analyst’s own screens, industry contacts, sell-side reports, conferences and questions from portfolio managers.
2. Analyze the business. This means reading filings and financial statements, including the income statement, balance sheet and cash flow statement, and working out what drives revenue, margins and capital needs.
3. Build a model and value the company. The analyst forecasts results and applies business valuation methods such as discounted cash flow or comparable multiples to estimate what the security is worth.
4. Meet management and gather information. Buy-side analysts meet company executives, sometimes through meetings a sell-side analyst arranges, and build expert networks of suppliers, customers, former employees and industry specialists.
5. Make the recommendation. The analyst tells the portfolio manager whether to buy, add to, trim, hold or sell, and how much conviction sits behind the call.
6. Monitor the position. After the fund invests, the analyst tracks earnings, news and the original thesis, and recommends selling when the thesis breaks or the price reaches fair value.

Because the fund’s money is at stake, buy-side analysts tend to spend a lot of time on risk: what could go wrong, how much the position could lose, and how it fits with everything else in the portfolio. A sell-side report can be optimistic without costing the analyst’s employer anything directly. A buy-side recommendation that goes badly shows up in the fund’s returns.

Buy-side coverage is usually wider. A fund might have one analyst covering all of technology and another covering industrials, while a large bank might have separate sell-side analysts for software, semiconductors and IT hardware. Sell-side analysts know their companies in great detail: product lines, management teams, supply chains and quarterly patterns. Buy-side analysts trade that depth for the ability to compare opportunities across a sector, relying partly on sell-side research for granular detail before forming their own view.

Funds used to rely mostly on research supplied by brokerages. As asset management grew and competition for returns intensified, large institutions built their own research teams to form independent views rather than share the same reports as every other client of a broker.

Buy-Side Macro Research

Not all buy-side analysts cover individual companies. Macro hedge funds, multi-asset managers and large pension plans employ researchers who study interest rates, currencies, inflation, central bank policy and economic data to position portfolios across asset classes. The sell-side counterpart is the bank economist or strategist, whose macro forecasts are distributed to clients and support the bank’s sales and trading business, while buy-side macro views drive the firm’s own trades.

What Sell-Side Analysts Do

A sell-side equity research analyst follows a defined list of companies, usually in one industry, and publishes regular research on them. A typical report contains:

• Financial estimates, such as revenue and earnings per share for coming quarters and years, built from the analyst’s model.
• A price target, the analyst’s estimate of where the stock should trade over a stated period, often 12 months.
• A rating, such as buy, hold or sell (some firms use overweight, equal-weight and underweight), signaling how the analyst expects the stock to perform.

To build those estimates, sell-side analysts talk with company management and with customers, suppliers, competitors and other people who know the industry. When an analyst starts following a company, it is called initiating coverage, and the first report usually sets out the full thesis and the initial rating.

Consensus Estimates and Whisper Numbers

The estimates of several sell-side analysts covering the same company are averaged into a consensus estimate. Earnings season is largely measured against that number. A company that beats consensus often sees its stock rise, and a miss often pushes it lower, though the guidance and details behind the headline figure can matter as much as the beat or miss itself.

Analysts’ expectations sometimes shift without their published estimates changing. The market’s unpublished expectation is called the whisper number, and when it differs from consensus, it can become the figure a company effectively has to beat.

Upgrades and downgrades can also move stocks in the short term, especially when an influential analyst changes a long-held view.

How Sell-Side Research Earns Money

Research departments do not usually sell reports outright the way a publisher sells subscriptions. In the traditional model, institutional investors pay for research indirectly through trading commissions. A fund directs some of its trades through a broker’s trading desk, and part of the commission compensates the broker for research and other services. These payments are known as soft dollars. In the US, Section 28(e) of the Securities Exchange Act of 1934 provides a safe harbor that lets money managers pay more than the lowest available commission in exchange for research, provided they decide in good faith that the commission is reasonable for the brokerage and research services received.

This model shapes the job. The sell-side analyst has to convince buy-side clients that the research is worth rewarding with order flow. That pulls the analyst into marketing: calling clients, hosting conferences, taking investors on site visits and arranging one-on-one meetings with company executives, which institutional investors value highly. Buy-side analysts often have a say in how their firm allocates trading among brokers, which gives them direct influence over sell-side analysts’ business.

The model works differently in Europe. Under the EU’s MiFID II rules, which took effect in January 2018, investment firms providing portfolio management had to stop receiving research bundled into trading commissions. Instead, they pay for it from their own resources or from a separate research payment account funded with client money under set controls. The UK carried these rules over after leaving the EU and has since moved to allow some forms of bundled payment again under conditions. Brokers serving British, European and Swiss clients have therefore had to price research as a service rather than rely only on commissions.

Conflicts of Interest

Sell-side analysts operate under pressure from two directions. Investors want candid views, including negative ones. Companies can limit management access for analysts whose views they dislike, and the analyst’s own bank may earn large underwriting and advisory fees from the same companies. A sell rating on an investment banking client has historically been a sensitive matter inside banks.

Those conflicts came to a head after the dot-com bust. In 2003, US regulators and ten major Wall Street firms reached the Global Research Analyst Settlement, which required the firms to pay about $1.4 billion and to separate research from investment banking. The same year, the SEC adopted Regulation Analyst Certification (Regulation AC), which requires analysts to certify that their reports reflect their personal views and to disclose whether they were paid for specific recommendations. FINRA rules, now consolidated in FINRA Rule 2241, govern equity research. They restrict investment bankers’ involvement in research, limit analysts’ personal trading in covered stocks and require disclosure of conflicts such as banking relationships.

Even with these rules, readers of published research should treat a rating as one input. Much of the most useful sell-side work, such as industry checks, model details and management meeting notes, reaches institutional clients through conversations rather than the public summary of a report.

Key Differences Between Buy-Side and Sell-Side Analysts

What Each Role Is Paid For

Sell-side analysts are largely paid for information flow, management access and the client relationships that generate trading and banking business. An analyst whose stock picks are only average can still be highly valued if clients find the industry insight and access useful. Industry polls, such as Institutional Investor’s long-running analyst rankings, have historically measured how clients rate sell-side analysts. A strong ranking adds to an analyst’s standing and pay.

Buy-side compensation ties more directly to results. Bonuses depend on the quality of the analyst’s recommendations and the fund’s overall performance. Pay varies widely on both sides. Sell-side analysts have often been described as earning more on average, while buy-side analysts at successful funds, particularly hedge funds, can earn considerably more than their sell-side peers.

Working Conditions

Sell-side analysts are often on the road for client meetings, conferences and roadshows, and earnings season can mean very long hours as they update models and publish notes on many companies at once. Buy-side analysts generally travel less and have more control over their schedules. The pressure is different rather than smaller: their calls are measured against real profit and loss.

Examples

The following hypothetical scenarios illustrate how the two roles interact. They do not describe any real company or firm.

Example 1: A Sell-Side Upgrade

An analyst at a brokerage covers eight semiconductor companies. After talking with equipment suppliers, she concludes that demand for one chipmaker’s products is recovering faster than expected. She raises her earnings estimates, lifts her price target and upgrades the stock from hold to buy. Her firm’s salespeople call institutional clients about the note, and several funds ask her to set up a meeting with the company’s chief financial officer. If the funds value the call and the meeting, they may route more trades through her firm’s desk.

Example 2: A Buy-Side Decision

An analyst at a pension fund covers the entire industrials sector. He reads the upgrade above, but his own model, built from the company’s filings, shows that the stock already prices in most of the recovery. He also worries that the company’s debt load leaves little room for error if demand stalls. He recommends that the portfolio manager hold the current small position rather than add to it. His recommendation never leaves the fund, and his bonus will depend partly on whether that judgment proves right.

Example 3: Beating the Consensus

Suppose five sell-side analysts forecast quarterly earnings per share of $1.00, $1.05, $1.10, $1.10 and $1.15 for a company. The consensus estimate is the average: $5.40 ÷ 5 = $1.08. Investors talking with the company’s suppliers believe results will be stronger, and the whisper number circulating among traders is $1.15. If the company reports $1.12, it beats consensus by 4 cents but falls short of the whisper number, so the stock may react less positively than the headline beat suggests.

Special Considerations

Can Both Roles Exist at the Same Firm?

Yes. Some large financial groups run a sell-side research department and an asset management arm with its own buy-side analysts. Conflict-of-interest rules and information barriers are meant to keep nonpublic information and research from passing between the two. Smaller firms usually specialize in one side because running both takes more resources and compliance infrastructure.

Where Credit Rating Agencies Fit

Credit rating agencies don’t fit neatly on either side. Their analysts assess the creditworthiness of issuers and debt securities, and in the common issuer-pays model, the company or government being rated pays for the rating. Because the ratings are published for the market rather than used to manage the agency’s own portfolio, the agencies are closer in function to sell-side research. They are, however, regulated separately (in the US, as nationally recognized statistical rating organizations) and do not earn trading commissions.

Career Moves Between the Two Sides

Analysts move between the two sides during their careers. A common path starts on the sell side, where junior associates build modeling skills, industry knowledge and contacts, and then moves to the buy side. Moves in the other direction also happen. Many analysts on both sides pursue the CFA charter, and some hold an MBA, though neither credential is a legal requirement for either role.

How Analysts Work With Other Professionals

Buy-side analysts work most closely with portfolio managers, who make the final investment decisions, and with traders, who execute them. Sell-side analysts work with their firm’s institutional salespeople and traders, who carry research ideas to clients. Within compliance limits, they also work with investment bankers, for example when vetting a company before an offering. Analysts on both sides talk with corporate executives, investor relations teams, industry experts and economists to gather information.

The Bottom Line

Investors reading analyst ratings and anyone weighing a research career both benefit from knowing which side produced the work. Sell-side ratings and price targets are published for clients by firms that also earn trading and banking fees, so treat a rating as one input. Buy-side views stay private and are judged by fund returns, which makes careful risk analysis central to that job.
