This study investigates the relationship between the number of stock concepts and future returns, as well as the economic mechanisms underlying this association. Using novel collected data, we find that stocks with a greater number of concepts earn significantly higher returns in the subsequent month, generating a six-factor adjusted annualized alpha of approximately 9.6% for a long-short portfolio. Although these stocks exhibit higher turnover, return volatility, and investor attention - features commonly associated with speculative concept-driven trading - an analysis of cross-listed AH twin stocks reveals that concept counts do not widen the AH premium. Moreover, the return premium persists for up to 15 months without significant reversal, whereas firms that engage in opportunistic concept-chasing exhibit pronounced long-run reversals, suggesting that the positive concept-return relation is not driven by speculative motives. The higher returns are primarily attributable to strong industrial policy support and sustained above-expectation operating performance. Firms with more concepts are more likely to receive government subsidies and deliver positive earnings surprises, effects that are amplified when their core concepts receive stronger national policy backing. In contrast, firms that pursue concepts lacking substantive business relevance are significantly less likely to obtain government subsidies and fail to achieve above-expectation growth. Regarding investor composition, institutional ownership of high-concept stocks increases modestly, while ownership by government-guided funds rises substantially - particularly for stocks whose core concepts are strongly supported by national industrial policies. Conversely, concept-chasing behavior by listed firms significantly reduces the ownership ratio of government-guided funds. Overall, our findings indicate that concept stocks in China’s capital market are not purely speculative but signal underlying national policies.

While government support programs are often effective at helping firms achieve their objectives, these programs may have unintended consequences. Motivated by this, this study empirically examines the impacts of receiving investments from government-guided funds (GGFs) on executive-employee pay gaps in Chinese public firms. The results from difference-in-differences analyses show that GGFs investments lead to a significantly greater widening of the pay disparities between executives and employees in recipient firms than in other firms after funding is granted. This widening gap is driven by a larger increase in executive compensation relative to employee wages. The mechanism analysis suggests that increased cash holdings associated with receiving GGFs create financial slack that facilitates managerial opportunism, ultimately resulting in greater pay gaps. These findings reveal an unintended consequence of GGFs, highlighting an overlooked agency cost of government financial support programs.
