Lecture 1: Investor Attention in Financial Markets
Lecture 2: Trading and Investments in Financial Markets
Fractional trading (FT)——the ability to trade less than a full share——allows low-budget retail investors to trade high-priced stocks. This paper quantifies FT’s impact on retail ownership and trading of high-priced stocks by exploiting its sequential introduction at four brokerage firms since November 2019. While small individually, fractional trades can work collectively to generate price pressures and reversals among high-priced stocks if coordinated during attention-grabbing events (such as being featured in Robinhood’s Top Mover list or stock split announcements). Post-FT, stock splits depend less on nominal share prices but generate more transitory, positive price pressures that facilitate insider selling.
文献二：Do Hedge Funds Strategically Misreport Their Holdings? Evidence from 13F Restatements
Hedge funds can subsequently amend their originally reported 13F quarterly holdings using restatements. We conduct the first systematic analysis of such filings, which are as common as confidential filings (used by funds to delay holdings disclosures), but affect three times as many stocks. Restated holdings are associated with significant abnormal returns, suggesting that some original holdings are strategically misreported to hide funds’ trading intentions. We construct a return gap measure to gauge the value added by such restatements and find that it predicts future fund performance. Finally, commonly used databases such as Thomson Reuters do not fully adjust for restatements.
