The statement describes that each stock's return in a year equals its dividend yield plus its capital gains yield, and that a weighted average of these returns is computed using each stock’s total market value to indicate the market's return.
Option 1: True — This is correct. The total return of a stock is the sum of its dividend yield and its capital gains yield. When you take a weighted average of all stocks’ total returns, weighting by each stock’s market value (market capitalization), you obtain a market-wide measure that reflects the performance of the overall market (i.e., the return on the market). This is the standard approach used in finance to derive a value-weighted market return, as opposed to a simple unweighted average, because larger companies exert more influence on the market’s overall performance.
Option 2: False — This would be incorrect because the statement is not asserting an unweighted average or an alternative method; it explicitly states a weighted average by each stock’s total market value. The description matches the conventional, value-weighted calculation used to represent the market return. The only potential caveat is that in practice, some indices use free-float adjustments or other refinements, but the core idea of a market-return measure being a weighted average of individual total returns remains true.
