AUM Scaling Constraints

This question tests whether candidates understand the link between fund size, market impact, and opportunity set. As a fund gets larger, it must deploy more capital without letting its own trades distort prices or crowd itself out of the best ideas, especially in less liquid parts of the market. Interviewers ask this because it shows whether you understand that returns are not only about picking good investments, but also about whether a strategy can be scaled efficiently in real markets.

The problem also reinforces why different parts of the equity market behave differently. Smaller companies and less liquid names can offer more pricing inefficiencies, but they are harder to buy and sell in size. Larger, more heavily followed companies are easier to trade, yet they tend to be more efficiently priced, so there may be fewer mispricings to exploit. A strong candidate should be able to explain this tradeoff clearly and connect it to fund capacity, liquidity, and alpha generation.
