July 2 (Reuters) - Blue Owl Capital maintained a 5% quarterly withdrawal limit for two of its private credit funds as redemption requests remained substantially above the cap despite falling by a few percentage points in the second quarter, sending the asset manager's shares up 8%. In shareholder letters released on Thursday, the New York-based firm said investors sought to withdraw $4.7 billion from the two funds in the second quarter, compared with $5.4 billion in the prior quarter.
