Canadian firms have different roots (e.g., more concentrated ownership and smaller size) than U.S. firms and Canadian regulatory enforcement follows a different route (principle- versus rule-based) that embodies the underlying intent of Sarbanes–Oxley (SOX). Financial restatements are more likely when Canadian firms have lower blockholder or management ownerships, lower proportions of unrelated directors, no financial savvy audit committee members and are not audited by prestigious auditing firms. To signal that they are dealing with the impact of agency problems on cash flow uncertainties, restating firms exhibit significantly higher turnovers of CEOs, CFOs and external auditors post-restatement, and they converge towards control-group governance post-restatement by making changes to the identified determinants of financial restatement likelihood. Consistent with prior results for U.S. firms, SOX had a small (extraterritorial) impact on the likelihood of post-restatement turnovers of management and other corporate overseers for Canadian restating firms.

We examine if an existing asset pricing model in an unconditional or conditional setting can explain the investment growth anomaly, as represented by higher returns on stocks of the firms with lower growth in capital expenditures. Our results indicate that the conditional Fama–French 3-factor model that allows factor loadings to be time-varying and further linked to firm-level characteristics and the business cycle can explain the anomaly.

We find a strong tendency for positive returns during the overnight period followed by reversals during the trading day. This behavior is driven by an opening price that is high relative to intraday prices. It is concentrated among stocks that have recently attracted the attention of retail investors, it is more pronounced for stocks that are difficult to value and costly to arbitrage, and it is greater during periods of high overall retail investor sentiment. The additional implicit transaction costs for retail traders who buy high-attention stocks near the open frequently exceed the effective half spread.
