Total return is usu- ally expressed as a percentage of the beginning price. Figure 1.19 is a histogram of the distribution of the annual combined returns for all stocks listed on the S&P 500 from 1928 to 2018 (91 years).24uli SPRET woh (a) Describe the overall shape of the distribution of rairh monthly returns. ib uoy bluow s ni (b) What is the approximate center of this distribu- ubong o tion? (For now, take the center to be the value with 1ed eroughly half the years having lower returns and half u having higher returns.) (c) Approximately what were the smallest and largest annual returns? (This is one way to describe the vari- ability of the distribution.) (d) A return less than zero means that stocks lost value in that year.
