興櫃流動性及波動性與IPO初期績效之關聯性

The Relationship of Liquidity and Volatility with IPO Initial Performances in Emerging Stock Market

指導教授 : 王朝仕

摘要


興櫃市場是一個集合未上市、上櫃公司的交易平台,就資訊的流動性、公開性來說較不夠透明,且交易方便性較低,在投資者相對較少下,而存在著成交量偏低,流動性不足的問題。 公開發行公司登錄成為興櫃市場股票,沒有資本額、獲利標準,股權分散等條件規定,故興櫃市場以中小型類股居多,公司股權結構較集中,投資風險相對較高,若遇景氣衰退,投資需求減少時,將產生流動性不足的情形,嚴重影響投資人權益,此凸顯流動性風險對興櫃市場的重要性。流動性不足容易產生買賣價差擴大、錯價及買賣無法成交的情形,且成交價格容易偏離真實的市場價值。 本研究以2005年3月至2014年6月,興櫃市場IPO的公司家數共500個樣本,最後取得有效樣本數為415個,研究公司股價與IPO初期績效之關聯性,並探討興櫃交易流動性(liquidity)、波動性(volatility)與IPO初期績效是否有顯著關係。實證結果顯示:公司股票流動性(交易量)越高,代表籌碼面不虞匱乏,使價格機能充份發揮,相對的也讓股價提前反應股票的市場價值,IPO的初期績效越小。波動性(股價波動)越大,表示股性活潑,投資人對其股價看法分歧,投資風險較大,IPO的初期績效也越大。

The emerging stock market in Taiwan provides a transaction platform for public companies not listed on Taiwan Stock Exchange and Taipei Exchange. However, the information circulation and publicity are not transparent and transactions are inconvenient in the emerging stock market, as compared with other stock exchange markets. Therefore, when the number of investor de-creases, there exists a problem of stock liquidity in this market. Because of no registration regulations about capital, profit and stock dispersion, most of the companies are the small-and-medium ones in the emerging market. In this situation, business recession will seriously reduce stock liquidity and thereby incur huge losses to investors. This indicates the especial importance of liquidity in the emerging stock market. Using the data of 500 IPO companies from 2005/3 to 2014/6, finally, to obtain a valid sample number is 415. this study explores the correlation of stock price with liquidity and volatility in the emerging market. The experi-mental result shows: 1. Higher stock liquidity indicates market mechanism is more functional, thus the initial performances of IPO companies are worse. 2. Higher stock volatility indicates more divergence of stock price among in-vestors, thus the initial performances of IPO companies are better.
