What Does an Investment Banking Analyst Actually Do All Day? A Task-by-Task Breakdown

In the eyes of outsiders, a day in the Investment Banking Division (IBD) is surrounded by billion-dollar deals, and socializing with business elites over drinks. However, the real investment banking life, especially for junior analysts and associates, is composed of endless meetings, intricate Excel models, PowerPoints, and immense pressure.

Early Morning: Waking Up to the Markets and Emails

For those in the IBD, regardless of what time they get to the office, the first thing after turning on the computer is always dealing with the mountain of accumulated emails. A Vice President (VP) or Managing Director (MD) might have sent comments on a valuation model at 2 AM. After a quick breakfast and coffee, junior bankers need to quickly organize their to-do lists and prepare the day's market update briefings, using Bloomberg terminals to gather key news.

Late Morning to Noon: Models, Calls, and Internal Coordination

For analysts, the morning is usually spent processing feedback received late the previous night or early that morning. This could mean repeatedly fixing a DCF (Discounted Cash Flow) model, updating assumptions, or re-running sensitivity analysis tables. Simultaneously, they need to handle "urgent requests" from associates, such as putting a comparable company analysis (Comps).

Lunch is typically compressed to under 30 minutes, with most people eating at their desks. Occasionally, an associate or VP might use lunch for an informal "coffee chat" with an analyst. This isn't just for relaxation; it's an important way to build internal networks and evaluate team members within the bank.

Afternoon: Client Communication and Due Diligence

The afternoon is the peak time for client activities and team collaboration. The types of meetings vary, ranging from due diligence calls with potential investors or discussions with clients about revisions to management presentation materials.

Between 3 and 5 PM is often time for internal review and coordination. Associates need to consolidate the day's transaction activity data, check all deliverables from the deal team, and prepare documents for the client for the next phase. During this process, the work products of junior staff, whether PowerPoints or Excel models are reviewed layer by layer.

Evening to Late Night: Revisions, Waiting, and the Long Slog

As other departments start wrapping up around 6 PM, the night is just beginning in the IBD. Although meetings decrease, this is the time to focus on the "big tasks" that require quiet concentration. Analysts need to complete the core work they didn't have time for during the day, such as building a complex financial model from scratch or drafting key sections of a Confidential Information Memorandum (CIM).

Dinner is usually between 7 and 8 PM, still eaten at the desk while staring at the screen. Around 10 PM, as VPs and MDs prepare to head home, they pass along their final revision comments and new tasks for the day to the junior staff. Analysts need to incorporate these comments such as adjusting PowerPoint layouts, fixing chart formats, updating data, and send them back to the associate for review; the associate may come back with further revisions, until everyone is satisfied.

A typical analyst's workday usually ends between 1 AM and 2 AM. During peak project periods, pushing through until 3-4 AM or even pulling all-nighters is not uncommon.

 Is the Investment Banking Grind Worth It?

A day in the Investment Banking Division is essentially a marathon of physical endurance, intellectual rigor, and emotional management. It's far from the hedonistic portrayal in movies like The Wolf of Wall Street, it's more about the monotony and perseverance of staring at a screen in a late night office, revising a PowerPoint for the 20^th time.

As one seasoned banker put it, the greatest satisfaction of this job comes from witnessing the moment your client's company rings the bell at their IPO.

For young people considering entering this industry, the key isn't whether you can endure 16-hour workdays, but whether you can maintain sensitivity to detail, a pursuit of professionalism, and a belief in long-term value under such high pressure. If you're ready for it, a day in the IBD will become one of the most valuable lessons of your career.
