This study examines the relation between securitization and loan performance using a comprehensive dataset from a major national mortgage lender. Loans remaining on the bank's balance sheet ex post incurred higher delinquency rates than sold loans, contrasting the negative relation between screening efforts and ex ante probability of loan sale explored by prior studies. Moreover, the performance gap between sold and retained loans was wider among the subsample of loans that were perceived as easier to resell. The investors' seeming advantage over the originating bank can mostly be explained by information revealed during the time between loan origination and sale.
