US investment bank JP Morgan Chase, which acquired struggling bank Bear Stearns in a cut price deal backed by the US Federal Reserve in March, will only offer jobs to a fraction of Bear Stearns Asset Management's staff.

Only 60 of Bear Stearns Asset Management's 450 staff in will stay at JP Morgan, and 40 of them work at risk analysis subsidiary Bear Measurisk, according to an anonymous headhunter cited by US publication Pensions & Investments.
