In our previous lesson, we established the fundamental purpose of an investment bank as a key intermediary in capital markets, connecting those who need capital with those who have it. We saw that its core activities are advising on mergers & acquisitions and raising capital. Now, we'll open the doors of the bank and examine its internal architecture.
This lesson addresses the main divisions of a typical large investment bank: the Investment Banking Division (IBD), Sales & Trading (S&T), Research, and Asset Management. Understanding the distinct function of each "silo" and how they interact is crucial for navigating the industry. It will clarify where the "investment banker" role you're targeting fits within the broader organization and how the work you'll eventually do in financial modeling and valuation supports the entire ecosystem.
The Bank's Blueprint: Front, Middle, and Back Office
Before we explore the main divisions, it's useful to understand a common high-level classification of banking roles. Think of the bank as a complex system with different tiers of operation.
- Front Office: These are the client-facing, revenue-generating divisions. This is where deals are made, securities are traded, and investment advice is given. IBD, Sales & Trading, Research, and Asset Management are all front-office functions. Your goal of becoming an investment banker places you squarely in this category.
- Middle Office: These groups provide crucial support to the front office, focusing on risk management, compliance, and legal functions. They ensure the bank's activities are within acceptable risk parameters and adhere to regulations.
- Back Office: This is the operational engine of the bank, handling trade confirmation, settlement, and IT infrastructure. They ensure that the transactions initiated by the front office are processed correctly.
While all parts are essential, the front-office roles are the ones directly involved in the core business of finance. Let's now dissect the four key divisions that make up the front office.
1. Investment Banking Division (IBD)
This is the division that most people think of when they hear "investment banking." It's the advisory heart of the bank, directly responsible for the two primary functions we discussed in our first lesson: M&A advisory and capital raising.
To get a practical sense of what junior bankers in this division do, the following video by a former J.P. Morgan analyst is very insightful.

This video, "Investment Banking vs. Equity Research vs. Sales & Trading," provides a clear, concise overview of what work in the Investment Banking Division entails.
Watch the section on Investment Banking. Pay attention to the description of the two main activities (M&A and fundraising) and the four typical tasks of a junior banker: building financial models, creating pitchbooks, conducting research, and coordinating meetings.
As the video explains, IBD is fundamentally a client-service business. Its professionals advise corporations, institutions, and governments on their most critical strategic decisions. To deliver this specialized advice, IBD itself is typically broken down into two types of groups:
- Industry Groups (or "Coverage" Groups): These teams focus on a specific industry, such as Technology, Media & Telecom (TMT), Healthcare, Energy, or Financial Institutions Group (FIG). They build deep, long-term relationships with companies in their sector, aiming to be the go-to advisor for any strategic need.
- Product Groups: These teams specialize in a particular type of financial product or transaction. They bring execution expertise to deals originated by the industry groups. The main product groups are Mergers & Acquisitions (M&A), Equity Capital Markets (ECM), Debt Capital Markets (DCM), and Leveraged Finance (LevFin).
For example, if a healthcare company wants to buy another company, its relationship bankers in the Healthcare (Industry) group will work hand-in-hand with the M&A (Product) group to analyze, structure, and execute the transaction. If that same company later needs to raise money by issuing new stock, the Healthcare group would then partner with the Equity Capital Markets (Product) group.
The following reading provides a formal definition of these groups.

2. Sales & Trading (S&T)
While IBD operates in the primary market creating new securities and advising on deals, the Sales & Trading division is the bank's gateway to the secondary market. Its role is to facilitate the buying and selling of financial securities (stocks, bonds, derivatives, etc.) for large institutional clients like hedge funds, mutual funds, and pension funds.
The division is split into two complementary functions:
- Sales: The sales team manages the relationships with institutional clients. They are not just order-takers; they are idea generators. They pitch trade ideas, provide market color, and distribute the bank's research, all with the goal of encouraging clients to trade through their firm.
- Trading: Traders execute the client orders brought in by the sales team. A key function here is market-making. Because institutional orders are often too large to be executed on the open market without causing major price disruptions, the trader acts as a principal. They might buy a large block of shares from a client into the bank's own inventory, then gradually sell those shares into the market. They earn revenue from commissions and the bid-ask spread—the small difference between the price they buy at and the price they sell at.
Let's return to the rareliquid video for a breakdown of this division.

This segment explains the distinct roles of sales and trading and clarifies the concept of flow trading.
Watch the section on Sales & Trading. Note the difference between the relationship-driven sales function and the execution-focused trading function. The explanation of why a large trade can't just be placed on an open exchange is particularly useful.
3. Research
The Research division acts as the bank's intelligence arm. Equity Research analysts are assigned to cover a list of public companies, typically within a specific industry. They become deep experts on these companies, building financial models, speaking with management, and analyzing industry trends.
Their primary output is detailed research reports that typically culminate in a rating—"Buy," "Sell," or "Hold"—and a price target for the company's stock. These reports are a key product used by:
- Institutional Clients: The Sales team distributes these reports to asset managers and hedge funds to inform their investment decisions and generate trade ideas.
- Internal Sales & Trading: The bank's own sales force uses the research to formulate compelling pitches for clients.
- Investment Banking Division: IBD bankers may use their firm's research to stay current on industry trends or get up to speed on a potential M&A target.
Historically, research was seen as a way to support the trading division. However, following conflicts of interest in the past, regulations have enforced a strict separation—often called a "Chinese Wall"—between the Research division and the Investment Banking Division to ensure research analysts' opinions are objective and not influenced by potential deal-making.
The video below offers a good summary of the day-to-day work.

Watch the section on Equity Research. Focus on the three main types of reports described: initiating coverage reports, industry primers, and company updates.
4. Asset Management (AM)
The first three divisions we discussed are primarily on the "sell-side"—they sell securities, sell advice, and sell research. The Asset Management division is the bank's own "buy-side" operation. This division manages large pools of capital on behalf of clients with the goal of generating investment returns.
Clients are typically institutional (pension funds, insurance companies, sovereign wealth funds) and high-net-worth individuals. The bank acts as a fiduciary, making investment decisions in stocks, bonds, real estate, and other assets to grow the client's money. In return, the bank charges a fee, usually calculated as a percentage of the total Assets Under Management (AUM).
It's important to distinguish the Asset Management division of an investment bank like Goldman Sachs Asset Management from a "pure-play" asset manager like BlackRock or Fidelity, although their fundamental function is the same.

Conclusion
You now have a map of the modern investment bank's front office. Each division has a distinct culture, skillset, and function, yet they work together as part of an integrated financial services machine.
Let's recap the key takeaways:
- Investment Banking Division (IBD): The advisory unit focused on M&A and capital raising, structured into industry and product groups. This is the destination for aspiring investment bankers.
- Sales & Trading (S&T): The market-facing division that facilitates secondary market trading for institutional clients through sales, trading, and market-making.
- Research: The intelligence unit that analyzes companies and securities, producing reports and investment ratings for internal and external clients.
- Asset Management (AM): The bank's internal "buy-side" firm, which manages clients' money to generate investment returns, earning fees on assets under management.
In our next lesson, we will build directly on this structural knowledge to explore how investment banks generate revenue. We will examine the specific fee structures—advisory fees, underwriting spreads, trading commissions, and asset management fees—that drive the profitability of each division we've discussed today. This will connect the bank's structure to its business model, a crucial piece of knowledge for your career goals.
