The divisions: who owns the client, who runs the deal

“Investment banking” means the private side³

In English usage the term is narrow: the corporate finance businesses that advise companies - M&A, restructuring and the raising of equity and debt. German usage often folds the trading floor in as well, which is where much of the confusion about what investment bankers do comes from. Investing money is not a bank function at all; it is the buy side, which banks serve.

Bankers advise the users of capital; markets serves its providers⁴

The markets division - sales, trading, structuring and research - looks after institutional investors and trades existing securities in the secondary market. Investment bankers almost always advise companies that need capital, and ECM and DCM are the primary market where new shares and bonds are born, which the trading floor later trades.

Inside information is why the wall exists³

Bankers on a deal hold information about their client that nobody outside has, and securities law in every major market forbids trading on it. So the private side is separated from the trading floor by information barriers - "Chinese walls" - and bankers may not share what they know with colleagues on the other side.

Research was walled off by settlement^5,6

In April 2003 ten large US firms settled with the SEC and other regulators for about $1.4bn over research skewed to win banking business, and agreed to physically separate research from investment banking and stop tying analysts' pay to banking revenue. The SEC ended those undertakings on 5 December 2025, on the view that FINRA Rule 2241 now manages the same conflicts.

Coverage pitches, product executes, and both do both^1,2

A coverage banker knows the sector and the client and builds the operating model; a product banker knows one transaction type across every sector and its mechanics cold. Mandates reach product groups more often because the client asks; coverage groups spend more time pitching. On a live deal the work is split by who has capacity, not by a rulebook.

The line is blurrier than the org chart¹

The notion that industry groups are all marketing and product groups all execution is wrong: coverage groups originate and advise, and product bankers pitch. What differs is where the specialist knowledge sits, not who does the work.

FIG is a separate language¹

The financial institutions group values banks and insurers, whose balance sheets are the business, so the models and the valuation methods differ from every other sector. That specialisation is what makes moving from FIG to a generalist role harder later.

Natural resources and real estate have their own maths¹

Oil and gas, mining and power models carry depletion, reserve probabilities and replacement rates; real estate is valued on different metrics from ordinary companies. Both suit someone heading for a fund in the same sector, where that specialism is the qualification.

Technology and healthcare lead to the corporate exits¹

A technology or healthcare group is an advantage for corporate development and venture capital in the same sector, because the buyer side of those industries hires for sector knowledge as much as for deal skills.

The financial sponsors group covers private equity firms¹

The sponsors group builds relationships with private equity firms, pitches ideas to them and works with their portfolio companies. It models less than leveraged finance, so it is a less direct route into private equity than the name suggests, but it does teach how the funds think.

Do not choose a group for its hours or pay¹

At analyst and associate level the differences in hours and pay between groups are small, and choosing on those grounds is described as borderline insane. The bank's name carries further than the group's, and a busy team teaches more than a prestigious one.

Choose the sector you can stay interested in¹

If a sector genuinely interests you, that is the strongest reason to pick its group: two years of long weeks are easier on work you find interesting. For business school applications later, the bank's reputation matters more than the group.

Ask where the analysts actually went¹

If private equity is the goal, ask the analysts in a group where their predecessors went. That is more accurate than any general ranking of groups, including the ones on this page.
