Most finance students can describe investment banking within minutes. Sales and trading gets a vague answer. The two divisions share the same building, often the same employer, but operate in completely different worlds.
This guide breaks down what S&T actually is, how the division is structured, who works in it, and what it takes to build a career there.
What Is Sales and Trading?
Sales and Trading (S&T) is the division of an investment bank responsible for buying and selling financial instruments on behalf of large institutional clients.
These instruments include stocks, bonds, currencies, commodities, and derivatives. Revenue comes from commissions, transaction fees, and the bid-ask spread the bank captures when making a market between buyers and sellers.
How the S&T Division Is Structured
A typical S&T division operates across two primary asset class desks:
- Equities desk — stocks, equity derivatives, and exchange-traded funds (ETFs)
- FICC desk (Fixed Income, Currencies, and Commodities) — government and corporate bonds, interest rates, foreign exchange pairs, and physical commodities such as oil and gold
The reason large institutional clients need these desks comes down to volume. If you want to buy 100 shares of a stock, an online brokerage handles it in seconds.
If you want to buy 500 million shares, executing that carelessly will move the market against you.
S&T desks step in to break large orders into smaller tranches, set buying schedules, and connect buyers with sellers at target prices without disrupting the underlying price.
The Four Core Roles in S&T
S&T is not a single job. The division runs on four distinct roles working in parallel.
Salespeople are the client-facing side. They build and maintain relationships with institutional investors such as hedge funds, pension funds, and mutual funds, pitch trade ideas, stay current on earnings reports and market conditions, and keep an open line between their clients and the traders executing on their behalf.
Traders are the executors. They price securities, manage the firm’s inventory of financial products, and execute the orders that salespeople bring in. They actively manage the firm’s risk exposure throughout the trading day.
Structurers sit behind the scenes. When a client needs a complex, customized instrument for hedging or a specific investment objective, structurers design it. They fill the gap when a standard product does not fit the client’s situation, and they support salespeople who may not have deep expertise in that particular product area.
Researchers supply the intelligence that salespeople use to pitch and traders use to position. Equity researchers analyze public companies and generate buy, hold, or sell recommendations.
Credit researchers focus on fixed income, examining debt instruments, credit risk, and bond market dynamics.
The Three Types of Trading
Not all trading desks operate the same way. There are three distinct models:
| Type | How it works | Risk to the firm | Typical profit source |
| Agency | Executes client orders as a pure intermediary | None | Commissions and fees |
| Proprietary | Trades the firm’s own capital for direct profit | High | Market gains |
| Flow | Hybrid; client orders flow through but desk also holds positions | Moderate | Spreads and positioning |
Following the 2008 financial crisis, the Volcker Rule (part of the Dodd-Frank Act) prohibited deposit-taking banks from engaging in prop trading.
True proprietary trading now lives primarily at independent prop firms and hedge funds. Most large banks today operate as flow and agency traders.
How S&T Differs from Investment Banking
Both divisions sit inside the same institution, but the work is structurally different in almost every way.
| Sales & Trading | Investment Banking | |
| Market focus | Secondary market (existing securities) | Primary market (new issuances, M&A) |
| Time horizon | Daily and short-term | Months to years per deal |
| Client interaction | Frequent, brief, transaction-driven | Deep, long-term, advisory |
| Revenue source | Spreads, commissions, fees | Advisory and underwriting fees |
S&T measures its day in transactions. An IB deal can take six to twelve months from pitch to close. The skill sets overlap at the analytical level, but the day-to-day rhythm is entirely different.

The S&T Career Path
The hierarchy in S&T follows the familiar investment banking ladder:
- Intern / Analyst — product knowledge, learning how instruments are priced, supporting senior desk members
- Associate — broader execution responsibilities, initial client exposure on the sales side
- VP — larger trading books, more autonomous decision-making, direct client management
- Director / SVP — senior client relationships, desk-level strategy input
- Managing Director — team oversight, risk management at the group level, hiring and personnel decisions
Compensation is performance-based and tied directly to market conditions. Junior analysts start in the low six-figure range. Senior traders and salespeople at top firms can earn well above $1 million in strong years.
The flip side is that weak market environments compress bonuses significantly, making S&T pay more volatile than a standard investment banking salary.
Skills That Actually Matter in S&T
To last in this division, you need a specific combination of hard and soft skills:
- Quantitative aptitude — mental math, pricing models, and statistical reasoning come up constantly, particularly on the trading side
- Market knowledge — real-time awareness of macroeconomic data, central bank decisions, earnings releases, and geopolitical developments that move asset prices
- Speed and decisiveness — markets do not wait for extended deliberation
- Communication — salespeople need to translate complex positions and trade ideas into clear, convincing pitches for clients managing their own mandates and risk constraints
- Adaptability — regulations shift, new products emerge, and market structures evolve; the professionals who last are the ones who update their knowledge continuously

Conclusion
Sales and trading is one of the most technically demanding roles in capital markets. The pace, the precision, and the direct link between performance and pay attract a specific type of professional.
Understanding how the division is structured, what each role contributes, and how it sits within the broader financial system is the right starting point before targeting a career here.
