1980 Mathematics Subject Classification: Primary 60G40.It is demonstrated that for each n \ge 2 there exists a universal constant, c_n, such that for any sequence of independent random variables {X_r, r \ge 1} with finite variances, E[max_{1\le i\le n} X_i] - sup_T EX_T \le c_n\sqrt{n - 1} max_{1\le i\le n}\sqrt{Var (X_i)}, where the supremum is over all stopping times T, 1\le T \le n. Furthermore, c_n\le 1/2 and lim inf_{n\to\infty} c_n 0:439485 ....NSF grant DMS 92-0958
