The premature jubilation that came with the news that Cuban President Fidel Castro was ailing breathed new life into a fund that invests in companies related to the island nation. Investment News reports that the Herzfeld Caribean Basin Fund saw its share price jump last week to a record $9.60 from about $7 before the news broke. By law, under the U.S. embargo, American companies are not permitted to invest directly in Cuba, but in companies that could benefit the country, such as Florida East Coast Industries, which is involved in real estate, railway and materials. Portfolio manager Thomas Herzfeld told IN that his firm has been “careful… never to do anything that would help Castro.” Herzfeld adds that whatever the future brings, in terms of leadership, the impact on portfolio countries will not be seen for some time as “there are U.S. laws that need to be reconciled,” John Kavulich of the U.S.-Cuba Trade and Economic Council said in an IN interview.
