Abstract

Special Purpose Acquisition Companies, or SPACs, have grown into one of the largest segments of the U.S. IPO market, raising more than $20 billion in gross proceeds since 2003. SPACs bear a strong resemblence to private equity funds, yet are largely free of the selection and survivorship biases that are often present in private equity datasets. I find that a portfolio of SPACs resembling "public LBOs" has a market beta near unity despite an average leverage multiple of nearly two, yielding new evidence regarding the systematic risk of leveraged buyouts. I also find that SPACs' highly predictable lifecycle yields highly predictable returns, with a monthly four-factor portfolio alpha of approximately 2% following the announcement of an acquisition and -2% after an acquisition has been completed. Finally, I provide evidence of a persistent discount in SPAC prices prior to the completion of an acquistion, which I attribute to fragmentation within SPACs' unique shareholder base.
