This study examines changes in stock liquidity, as measured by the bid/ask spread, when a stock is added to the S&P 500 Index. The paper presents evidence of a significant decrease in the bid/ask spread upon S&P 500 addition, however, this effect is limited to only those stocks that were not trading listed options. Further, the decrease in the bid/ask spread for nonoptioned stocks is accompanied by a significant and permanent increase in share price and trading volume. While optioned stocks experience a permanent increase in trading volume, they experience only a temporary increase in share price. The findings for optioned stocks support the hypothesis that the price and volume effects associated with S&P 500 addition derive from temporary price pressure. Findings pertaining to the nonoptioned stocks indicate that the price and volume effects associated with S&P addition reflect enhanced stock liquidity. The decrease in the bid/ask spread for nonoptioned stocks is attributed to informational efficiencies achieved via index arbitrage trading, and it is argued that this effect is mitigated for optioned stocks due to the pre-existence of arbitrage trading between the option and the underlying stock. 相似文献

This paper investigates market behaviors (such as volatility, depth, and volume) and order-flow decomposition in a pure limit order futures market, the Taiwan Futures Exchange. The results are different from those in equity markets due to relatively high adverse selection costs in futures markets. We show that a volatility (depth) increase is followed by a depth (volatility) decrease; a market order increase (decrease) subsequently induces higher (lower) volatility; and a limit order increase (decrease) results in more (less) market orders and limit orders. When the upside (downside) volatility rises, buyers decrease (increase) subsequent limit bid orders, and sellers increase (decrease) limit ask orders. 相似文献

We compare the liquidity providing behavior of NASDAQ market makers in 2010 to their behavior in 2004. We examine how frequently market makers are at the inside quote, what market and stock specific factors influence market makers’ behavior, and the relation between market maker participation and intraday bid‐ask spread patterns. We observe a decrease in the percent of the trading day dealers’ quote at the inside, a decline in the number of market makers, and a decrease in the influence market makers have on intraday spread patterns. The results suggest that the role of NASDAQ market makers declines over time. 相似文献

Spirited disagreement exists among online auction participants over the ethics of sniping: delaying one's bid until the closing seconds of an online auction. Through analysis of the structural features of online auctions and by deploying Rawls's (1955) distinction between justifying an action under a practice and justifying the practice itself, I argue that: (i) the disagreement is better conceived as one over the ethics of online auction hosting (and therefore, over business ethics) than over the ethics of online auction participation; (ii) so conceived, the argument against sniping is nonetheless implausible; and (iii) the disagreement remains interesting not on the merits, but for the curious fact that it is bidders who complain about sniping. 相似文献

招商引资在促进经济发展的过程中起到了举足轻重的作用。本文首先在深入分析青海省情的基础上,认为招商引资具有优越的客观条件和良好的宏观、中观及微观环境。其次运用协整理论,结合西部大开发以来青海省实际招商引资的经验数据,研究了招商引资与经济增长的协整关系。结果表明,招商引资到位资金每增长1个百分点,对青海经济增长会起到1.02%拉动作用,且近年来招商成效有加速势头,预测显示:2015年招商引资到位资金将达到484亿元左右。最后提出了进一步做好招商引资工作、服务好当地经济发展的政策建议。 相似文献
