Major Equity Indices

This question practices core market knowledge that comes up often in capital markets and sales and trading interviews. You need to know how the S and P 500, the Dow Jones Industrial Average, and the Nasdaq 100 differ in terms of constituent selection, weighting methodology, and index return measurement, including the distinction between price return and total return indices. It also tests whether you understand why index construction matters, since changes in weighting, float adjustment, and divisor mechanics can materially affect how an index behaves and how to interpret its moves. Interviewers ask this kind of question to see if candidates can speak fluently about benchmark indices, explain what drives index levels, and show they understand the practical market significance of index design.
