Around the end of lock-ups expiration, investors are concerned about disposal of largest shareholder`s ownership. Prior studies analyzed the relation between lock-ups and IPO stock prices, using the lock-ups expiration of ex-ante disclosure data. This study examines the market reaction and ownership change, using the lock-ups expiration of disclosure data and share restoration data. The analysis shows that there exist time gap of around 3 months on average between lock-up expiration and share restoration. Therefore, it is important to study the market reaction around the date of share restoration. Prior studies did not analyze the lock-ups, using actual share-restoration data and ownership data. Using actual lock-ups data, we investigate the impact of lock up on Korean capital market about IPO stock price behavior, ownership changes and investor`s reaction. The main results of this study are as follows. First, we did not find that significant decline of the largest shareholder`s CAR around the end of lock-ups expiration date and actual share-restoration date. However, we observed that the ownership of VC and institutional CAR continues to decline after the initial high returns. Second, we did not find that reduction of largest shareholder`s ownership around the end of lock-ups expiration date and actual share-restoration date. Thus the market reaction around lock-ups expiration may be recognized as unnecessary social costs associated with an information asymmetry. |
