What does a trader do: Answer Guide 2027

A trader buys and sells securities to profit from price movements and to provide liquidity to clients — quoting prices, managing risk, and staying within limits all day. In a what trader does interview, distinguish market-making (earning the bid-ask spread for clients) from proprietary-style risk-taking, and stress risk management: a trader's real job is managing positions, not predicting markets.

What This Tests in a What trader does interview Question

• Whether you understand the day-to-day: pricing, quoting, executing, and managing inventory risk — not just 'buying low and selling high'.
• Whether you know the market-maker versus risk-taker distinction and how each gets paid.
• Whether you grasp that risk limits and discipline define the job more than market calls.

How to Answer a What trader does interview Question

• Describe the core loop: take client flow or express a view, quote and execute, manage the resulting position against risk limits.
• Distinguish roles: market-makers earn spreads by standing ready to buy and sell; directional traders profit from price views.
• Emphasize risk: position limits, stop discipline, and hedging are what keep a trader employed; P&L is the scoreboard, not the strategy.

Example phrasing: "A trader provides liquidity by quoting buy and sell prices, then manages the risk of the resulting positions within strict limits. Market-makers earn the spread on client flow; others take directional views — but in both cases the job is really risk management, because undisciplined risk ends careers."

Common Mistakes in a What trader does interview Question

• Describing trading as gambling or pure speculation — it signals you do not understand institutional markets.
• Forgetting clients entirely; much of sell-side trading exists to serve client flow.
• Ignoring risk management, which interviewers consider the heart of the answer.

Markets interviewers ask this to check whether you romanticize trading or understand it. Candidates who lead with liquidity provision and risk management sound like future colleagues; those who lead with 'making big bets' sound like tourists.
