English to Spanish Bus/Financial Finance (general) goes long recent winners and shorts recent losers

Me encuentro con estos términos en el siguiente contexto:

The model can generate positive correlations between price changes and expected returns implying that firms with recent
stock price declines are also those firms with lower expected returns going forward. A momentum strategy that goes long recent winners and shorts recent losers among distressed firms may therefore generate a large spread in expected returns

Aguardo su ayuda.

Desde ya muchas gracias.
