6. Discussion
Some researchers have pointed to the precautionary benefits of cash (Opler et al., 1999; Mikkelson & Partch, 2003), whereas others have emphasized the adaptive benefits of cash (e.g., Denis & Sibilkov, 2010; Brown & Petersen, 2011). Research that draws attention to the downside of cash holding has found detrimental effects on market performance only at very high level of cash holdings (e.g., N89% of assets; Kim & Bettis, 2014). We found that the benefits and costs of cash holdings are exacerbated during a recession. As presented in Fig. 1, we find a much more pronounced inverse-U shaped relationship between cash and market performance during a recession compared to the diminishing returns curve for before-recession. There are higher benefits to cash holdings at low levels during a recession (from 0 up to 0.4), but the penalty for holding cash starts much earlier (0.4) than in pre-recession period (0.9).
