We investigate whether access to information prior to an IPO generates a trading advantage after the IPO. We find that limited partners (LPs) of venture capital funds obtain high returns when they invest in newly listed stocks backed by their funds. These returns are not explained by LPs'...

We find strong evidence that net insider selling is positively associated with future stock return volatility, consistent with insider selling increasing outside investors' uncertainty. The positive effect of net insider selling is significantly stronger when the volatility is measured around...

We find significant impact of insider trading activity on the long-run performance of IPOs. We show that, at the aggregate, insiders are net sellers in IPOs that generate positive long-run returns, while they are net buyers in those that underperform. When we analyse individual trades, we find...

Asset turnover, an inside component of profitability in the Dupont analysis, has an ability to predict average stock returns. In the portfolio sort, firms with high asset turnover earn high expected returns, which is unexplained by risk-adjusted asset pricing models. In the cross-section, asset...
