BOSTON/NEW YORK, April 23 (Reuters) - U.S. money managers Janus Capital Group Inc (JNS.N: Quote, Profile, Research) and Invesco Ltd (IVZ.N: Quote, Profile, Research) reported surprisingly weak quarterly profits on Thursday as stock market declines and investment losses carved into revenue.

Federated Investors Inc (FII.N: Quote, Profile, Research), relying on its stable of funds that appeal during turbulent markets, earned more during the quarter, but not enough to overshadow a $20.1 million charge that resulted in lower profit.
