We document that announcement-period abnormal returns of sovereign wealth fund (SWF) equity investments in publicly traded firms are positive but lower than those of comparable private investments. Further, SWF investment targets suffer from declining return on assets and sales growth over the following three years. Our results are robust to controls for target and deal characteristics and are not driven by SWF target selection criteria. Larger discounts are associated with SWFs taking seats on boards of directors and with SWFs under strict government control acquiring greater stakes, supporting the hypothesis that political influence negatively affects firm value and performance.

We provide evidence that higher-quality disclosure standards are associated with stock returns that are less sensitive to noise driven by investors' moods. We identify return-mood sensitivity (RMS) based on the association between index returns and urban cloudiness, a source of short-term variation in mood. Based on a stylized model, we predict and find evidence consistent with higher-quality disclosure standards reducing RMS by tilting susceptible investors' trades toward information and by facilitating sophisticated investors' arbitrage. Our findings suggest that disclosure standards play an important role in enhancing price efficiency by reducing noise in returns, particularly noise related to investors' short-term moods.
