Sponsored While the surge in blank-check companies worries some investors, Mark Yusko of Morgan Creek Capital Management sees a good entry point for an actively managed exchange-traded fund to sort through the frenzy — and bet on innovation. The Morgan Creek – Exos SPAC Originated ETF, which began trading this week, will own between 50 and 100 special purpose acquisition companies, Yusko, Morgan Creek’s chief executive officer and chief investment officer, said in a phone interview. About one-third of the SPACS held by the ETF won’t have announced a merger, he said, with the balance having already agreed to a business combination.
