Markets Careers

The Buy Side

The buy-side is where the money that gets invested in the markets actually lives. Asset managers take capital from clients, pension funds, endowments, insurers, wealthy individuals and other institutions, and invest it across stocks, bonds and other assets in pursuit of returns.

Unlike investment banks, who mostly make money on the spread between buying and selling for other people, asset managers make money by owning assets themselves and growing their value over time, largely through management and performance fees charged to their clients. That means their incentives are directly tied to the returns they generate: if the fund does well, so do they.

Buy-side firms come in several flavours, each with a different approach to risk and return:

  • Traditional asset managers and mutual funds, who invest client money in relatively long-only portfolios across stocks, bonds and other assets
  • Hedge funds, who take more aggressive positions, often using leverage and short-selling, in pursuit of higher (and riskier) returns across any asset class
  • Pension funds and insurers, who manage vast long-term pools of capital and prioritise steady, reliable growth over decades
  • Sovereign wealth funds, who invest on behalf of entire nations, often across both public and private markets

Whatever type of firm you're at, the job is the same at its core: decide what to buy, what to sell, and when, in order to generate the best possible returns for the people who trusted you with their money.

Portfolio Manager

Portfolio managers decide what the fund actually owns.

What do they do?

As a portfolio manager, your job is to decide what assets the fund should hold, in what size, and for how long. You set the fund's overall view and strategy, research individual opportunities (or oversee analysts who do), and take ultimate responsibility for performance. At smaller or more specialised funds, PMs often do their own research and idea generation from scratch, while at larger funds they typically lead a team of analysts who bring them ideas to approve, size and manage.

The line between portfolio management and trading varies a lot by firm. At some funds, especially smaller or more systematic ones, portfolio managers execute their own trades directly, so ideation and execution sit with the same person. At larger, more traditional funds, PMs decide what to buy and leave the mechanics of getting the trade done to a dedicated trading desk.

A day in the life

A portfolio manager's day starts before the market opens, catching up on overnight news and how it affects existing positions. Most of the day is spent reviewing research, meeting analysts and company management, and deciding what changes to make to the portfolio. PMs check in with their traders throughout the day to track how orders are being filled.

You’ll be suited for this role if

  • You're comfortable making a call on limited information and living with being wrong
  • You want ownership over what the fund actually buys and sells, not just how it gets done
  • You're resilient: even the best PMs get it wrong a meaningful share of the time
  • You think in months and years rather than minutes, and you're happy to be judged on that timescale
