Special Purpose Acquisition Companies (SPACs) are shells initiated with the sole intent of acquiring a single privately held company. SPAC shareholders vote on this acquisition, and in this paper we identify the factors that affect approval probability. Surprisingly, the data indicate more experienced managers and boards do not enhance the probability of deal approval. Similarly, glamor underwriters and larger underwriter syndicates are less likely to be associated with successful SPACs. Further, we find a negative relation between the presence of active investor (hedge funds and private equity funds) shareholdings in a SPAC and approval probability.

Portfolio optimization using private equity is typically based on one of three indices: listed private equity, transaction-based private equity, or appraisal value-based private equity indices. However, we show that none of these indices is fully suitable for portfolio optimization. We introduce here a new benchmark index for venture capital and buyouts, which is updated monthly, adjusted for autocorrelation (de-smoothing), and available contemporaneously. We illustrate how our benchmark enables superior quantitative portfolio optimization.
