Each year a small clothing company produces a new sweater design. The sales of each design have been shown to be independent random variables. Owing to changes in fashion, the company produces each design for three years. Assume that the value of the firm depends on its sales and that we can write the value at time tt as follows: V_t = S_t + S_{t-1} +S_{t-2}Vt​=St​+St−1​+St−2​ where S_tSt​ equals sales at time tt. Which of the following will be true of the firm’s value? More than one may be true.
