Morgan Stanley's James Gorman rates himself an A-minus CEO but says he doesn't want to be the boss anymore

• Outgoing Morgan Stanley boss James Gorman gave himself an A- grade as CEO of the investment bank.
• Gorman became Morgan Stanley's CEO in 2010 and grew the company.
• He said he's done being CEO after 14 years in the job and looks forward to more teaching.

Outgoing Morgan Stanley CEO James Gorman gave himself an A- grade for his time at the investment bank.

"We did well, objectively. The stock has basically tripled," the 65-year-old executive told in a wide-ranging interview with the Financial Times published over the weekend.

The 65-year-old justified the grade by saying it would be immodest to give himself a higher grade but "false modesty" to mark himself lower.
