So, Anshu Jain's son works in fixed income at J.P. Morgan

Research by Facebook suggests that if your father works in 'business and finance,' you're likely to get a job in sales or the military. This does not appear to hold for Arjun Jain, son of Anshu. Anshu Jain being the ex-CEO of Deutsche Bank.

Arjun has followed his father into fixed income sales and trading. According to his FINRA broker report, the Princeton University and St. Paul's London educated Arjun has been quietly working for J.P. Morgan's US fixed income division since June 2014. Who knew?

The big question is why it was that Arjun went to work for J.P. Morgan instead of Deutsche - particularly as his father was still in control when he made his debut. Lloyd Blankfein's sons, Jonathan and Alex both trialed jobs at Goldman, during their dalliances with finance careers. (Jonathan is currently studying at Harvard and Alex hasn't been registered with FINRA since leaving Goldman in 2011.)

Citigroup is the leading global bank for fixed income trading according to the most recent market share figures from Greenwich Associates. Deutsche Bank and J.P. Morgan also rank in the top five, although Greenwich didn't break out their individual positions.

Fixed income revenues at Deutsche Bank rose 10% last year and fell 11% at J.P. Morgan. Maybe Arjun made the wrong choice?

It's not clear whether Jain junior went through the usual round of internships and spring weeks. At Princeton he seems to have busied himself with photography. He was also in a band called 'Divergence,' the (discontinued) website of which describes him as an "international man of mystery."
