The Power 50

Business has its ups and downs, and so, naturally, do women in business. (Bye-bye, Martha!) But the story of this list is one of achievement: The credentials of these women, including the 13 newcomers, are the strongest yet.

Zoe Cruz
16. Zoe Cruz
Co-President
Morgan Stanley (MS)
2006 rank:  19
Age: 52

She oversees institutional securities and global wealth management, which together account for more than 80% of the bank's $34 billion in revenues. Named co-president in early 2006, Cruz has tremendous pull within the company, where she has worked for 26 years. She reports directly to John Mack (who sometimes refers to her as the "Cruz missile") and is considered a possible successor.
