MARKET REACTION TO NYSE LISTINGS: TESTS OF THE MARKETABILITY GAINS HYPOTHESIS

This study examines the market reaction to listing on the New York Stock Exchange (NYSE). The marketability gains hypothesis states that investors expect liquidity gains for the less liquid over-the-counter (OTC) stocks but not for their liquid counterparts after their listing on the NYSE. The hypothesis is supported even after accounting for other firm-specific news releases. Stocks with low liquidity on the OTC exhibit a positive reaction, whereas stocks with high liquidity show a non-positive market reaction around the announcement of the listing application. The findings imply that the two different marketplaces, NYSE and OTC, are suitable for stocks with different liquidity characteristics.     

Herd behavior and equity market liquidity: Evidence from major markets

This paper provides new evidence on the relation between herd behavior and equity market liquidity, an issue that has been neglected when it comes to studying herd behavior towards the consensus. We use equity price data for the G5 markets, and initially find no evidence of herding. When, however, we condition on the liquidity of stocks we find significant evidence of herd behavior for high liquidity stocks, for most countries, a result robust to different definitions of the crisis period and different measures of liquidity. The only exception is Germany for which there is weaker evidence of herding in high liquidity stocks. Variance decomposition tests indicate that the variance of the average equity market liquidity is affected by return clustering, especially during the crisis and post-crisis period an effect that is more pronounced for the US market.     

OTC MARKET SWITCHING AND STOCK RETURNS: SOME EMPIRICAL EVIDENCE

In this study the effect on the common stock returns of 278 firms that switched OTC market segments from 1982 to 1987 is examined. It is hypothesized that abnormally positive returns are associated with news of the move from the NASDAQ to the NASDAQ National Market System (NMS) and that the market responds more favorably during pre-NMS inclusion for stocks with low versus high liquidity before switching. Using event study methodology, results support these hypotheses. Unlike post-listing studies, the evidence reveals no anomalous return behavior during the post-NMS inclusion period studied.     

我国社保基金持股偏好研究

社保基金在证券市场上的投资表现会直接影响其运行的稳定性,由于其资金来源的特殊性,社保基金对于选择投资对象有没有明显的偏好呢？本文利用2008—2018年我国A股上市公司的数据,研究社保基金的持股偏好。研究表明,社保基金在进行投资时对于经营业绩好、风险性低、股权集中度高、估值偏低的股票具有明显的偏好。进一步研究发现,与保险公司偏好股权集中度低的股票、公募基金偏好流动性高的股票相比,社保基金更偏好股权集中度高的股票,而对于流动性高的股票并没有明显的偏好。     

Sources of liquidity for NYSE-listed non-US stocks

We examine the components of displayed (quoted) liquidity and the amount of non-displayed liquidity on the NYSE for a sample of non-US stocks. Consistently with prior work, non-US stocks have less displayed liquidity than similar US stocks. Extending prior research, we find that this is true both in the limit order book and on the floor. As Domowitz et al. [Domowitz, I., Glen, J., Madhavan, A., 1998. International cross-listing and order flow migration: Evidence from and emerging market. Journal of Finance 53, 2001–2027] posit, non-US stocks from transparent/linked home markets have more displayed NYSE liquidity when the home market is open but non-US stocks from opaque/non-linked home markets have more NYSE displayed liquidity when the home market is closed. Non-US and US stocks have similar supplies of non-displayed liquidity, consistent with the idea that the conditional nature of non-displayed liquidity allows NYSE traders to mitigate adverse selection problems inherent in trading non-US stocks. Our results imply that non-US stocks have less total (displayed plus non-displayed) liquidity than US stocks.     

Higher-Order Systematic Comoments and Asset Pricing: New Evidence

We provide evidence supporting Rubinstein's (1973) model that if returns are not normal, measuring risk requires more than just measuring covariance. Higher-order systematic comoments should be important to risk-averse investors who are concerned about the extreme outcomes of their investments. Our paper shows that the Fama-French factors [SMB (return on small stocks less the return on big stocks), HML (return on high book-to-market stocks less the return on low book-to-market stocks)] as well as the momentum and market liquidity factors can be explained by the higher-order systematic comoments, and it lends support to the traditional covariance risk-based theory without having to resort to behavior assumptions.     

How do designated market makers create value for small-caps?

A poor liquidity level and a high liquidity risk significantly raise the required return for small-cap stocks. Euronext allows these firms to hire designated market makers (DMMs) who guarantee a minimum liquidity supply for a lump sum annual fee. In an event study based on 74 DMM stocks, we find that the contract improves liquidity level, reduces liquidity risk, and generates an average abnormal return of 3.5%. DMMs participate in more trades and incur a trading loss on high quoted-spread days (days when their constraint is likely to bind). Finally, DMMs reduce the size of pricing errors.     

UNLISTED TRADING PRIVILEGES,LIQUIDITY, AND STOCK RETURNS

In this study we examine the effect of dual trading through unlisted trading privileges (UTPs) on liquidity and stock returns. Stocks with UTPs trade in a different market structure than stocks listed and traded only on the AMEX and NYSE. Differences in market structure may affect stock returns through liquidity services provided by the competing markets. The sample comprises 852 AMEX and NYSE firms that began unlisted trading on the Philadelphia, Pacific, Midwest, or Cincinnati exchanges between 1984 and 1988. The results show significantly positive abnormal returns around the SEC's announcement of a regional exchange's filing for UTPs. The results also suggest that increased competition improves trading liquidity. Only stocks with low liquidity before UTPs announcements experience significantly improved liquidity and positive stock returns.     

隐性杠杆约束、流动性风险和投资者情绪

本文以2003—2019年间开放式主动管理型的股票型和偏股型基金为样本,以持仓占比为权重估算基金投组中A股的总市场风险暴露,检验结果表明,该序列上升反映了基金面临的隐性杠杆约束收紧,刻画了市场的弱流动性。内在逻辑在于,流动性收紧时,投资者难以通过融资直接增加杠杆,更倾向于重仓持有高市场风险头寸的股票而间接实现杠杆。本文发现隐性杠杆约束所刻画的风险在股票或基金收益截面上的无条件定价基本失效,而条件定价则依赖于低市场情绪与弱流动性。分解基金持股的敞口,进一步发现,因中小盘基金在流动性收紧时具有更强的流动性偏好,其持股的市场风险头寸能够更敏锐地捕捉到弱流动性风险。     

Order-to-trade ratios and market liquidity

We study the impact on market liquidity of the introduction of a penalty for high order-to-trade ratios (OTRs), implemented by the Italian Stock Exchange to curtail high-frequency quote submission. We find that the fee is associated with a collapse in the quoted depth of the stocks that make up the bulk of trading in Italian equities and with an increase in price impacts of trading across the treated stocks. Spreads do not change, however. Stocks from a pan-European control sample show no such liquidity changes. Thus, the Italian OTR fee had the effect of making Italian stocks markets more shallow and less resilient. Large stocks are more severely affected than midcaps. We also find evidence of a limited decrease in turnover. Consolidated liquidity, constructed by aggregating across all electronic trading venues for these stocks, decreases just like that on the main exchange. Thus, liquidity was not simply diverted from the main exchange, it was reduced in aggregate.     

Analyst Disagreement,Mispricing, and Liquidity*

This paper documents a close link between mispricing and liquidity by investigating stocks with high analyst disagreement. Previous research finds that these stocks tend to be overpriced, but that prices correct downwards as uncertainty about earnings is resolved. Our analysis suggests that one reason mispricing has persisted through the years is that analyst disagreement coincides with high trading costs. We also show that in the cross‐section, the less liquid stocks tend to be more severely overpriced. Additionally, increases in aggregate market liquidity accelerate the convergence of prices to fundamentals. As a result, returns of the initially overpriced stocks are negatively correlated with the time series of innovations in aggregate market liquidity.     

Liquidity and Stock Exchange Listing

This study examines the pattern of stock price behavior for a sample of 71 firms that moved from NASDAQ and NASDAQ/NMS to the American Stock Exchange (AMEX) between 1982 and 1987. The study tests the liquidity gains hypothesis, which states that investors expect liquidity gains for the less liquid over-the-counter stocks but not for their more liquid counterparts after their listing on the AMEX. The results support the hypothesis by showing a significant difference between the two groups of stocks on the day the AMEX announced approval of the listing. Thus, companies with low liquidity are the largest beneficiaries of listing. The evidence provides little support for the anomalous negative pattern of returns during the post-listing period reported in previous studies.     

High-frequency trading and stock liquidity: An intraday analysis

This paper studies the impact of high-frequency trading (HFT) on intraday liquidity of CAC40 stocks listed on Euronext. Spreads display an intraday L-shaped pattern, while quoted depth follows an inverse pattern: low at the open and increasing towards the end of the trading day. When liquidity demand is particularly high, there is a high rate of order cancellations attributable to high-frequency traders who use frequent order cancellations to strategically manage their limit orders and close positions near the market close. Using the generalized method of moments estimator, we generate strong evidence that greater intensity of HFT is associated with lower spreads and higher depth. The positive effect of HFT on liquidity is due mainly to decreased adverse selection costs arising from asymmetric information among market participants.     

Cross-listing and liquidity in emerging market stocks

In this study, we analyze liquidity costs for stocks and ADRs from the four main Latin American markets. The results indicate that international investors are exposed to different trading costs in Latin America, with market location and firm size as important determinants. In the local market, stocks that cross-list internationally do not always present a liquidity cost advantage relative to non-cross-listed stocks. When the ADR and the local stock markets are compared, large firms present lower trading costs in the home market. The opposite occurs for small firms.     

The Cross-Section of Volatility and Expected Returns

We examine the pricing of aggregate volatility risk in the cross‐section of stock returns. Consistent with theory, we find that stocks with high sensitivities to innovations in aggregate volatility have low average returns. Stocks with high idiosyncratic volatility relative to the Fama and French (1993, Journal of Financial Economics 25, 2349) model have abysmally low average returns. This phenomenon cannot be explained by exposure to aggregate volatility risk. Size, book‐to‐market, momentum, and liquidity effects cannot account for either the low average returns earned by stocks with high exposure to systematic volatility risk or for the low average returns of stocks with high idiosyncratic volatility.     

Stock liquidity and the Taylor rule

This paper examines how stock market liquidity and commonality in liquidity are impacted by real-time output gap and inflation, as these macroeconomic variables have been shown to be the main drivers of monetary policy according to the Taylor rule. We show that an increase in the output gap and inflation lowers stock liquidity and increases commonality in liquidity, since it points to a contractionary monetary policy and is likely to lead to a decline in the liquidity providers' funding liquidity. This effect is larger for stocks with low market capitalization and low liquidity.     

LIQUIDITY AND QUOTE CLUSTERING IN A MARKET WITH MULTIPLE TICK SIZES

We analyze market liquidity (i.e., spreads and depths) and quote clustering using data from the Kuala Lumpur Stock Exchange (KLSE), where the tick size increases with share price in a stepwise fashion. We find that stocks that are subject to larger mandatory tick sizes have wider spreads and less quote clustering. We also find that liquidity providers on the KLSE do not always quote larger depths for stocks with larger tick sizes. Overall, our results suggest that larger tick sizes for higher priced stocks are detrimental to market liquidity, although the adverse effect of larger tick sizes is mitigated by lower negotiation costs (i.e., less quote clustering).     

Commonality in liquidity: Evidence from the Australian Stock Exchange

Several studies have reported strong evidence of commonality in liquidity in US markets. The present study uses the research design of Chordia et al. (2000) to examine commonality in liquidity for a broad sample of stocks listed on the Australian Stock Exchange (ASX). In contrast to previous research, there is some evidence of market‐wide commonality in liquidity for ASX stocks, but it is less significant and less pervasive than that observed in other markets. These results are consistent with explanations based on differences in market structure between the USA and Australia.     

Liquidity Dry-ups in equity markets

This paper examines how mutual fund investors’ demand for liquidity provision endogenously affects stock liquidity in the equity market. We find that actively managed funds in the US tend to hold less liquidity than their respective benchmarks, which leads them to rely on only a small fraction of liquid stocks when it comes to liquidity demand. Using mutual fund sell transactions, we further show that mutual funds tend to sell more liquid stocks in their holdings when experiencing outflows. Concentrated sales of liquid stocks, however, significantly reduce the liquidity of these stocks, resulting in liquidity deterioration or dry-up among highly liquid stocks in periods of high market-wide liquidity demand. Overall, the results indicate that mutual funds fail to predict the liquidity of the asset at purchase.     

Making a Market with Spreads and Depths

Abstract:   In this paper we study the quote revision behavior of NASDAQ market makers by analyzing inter‐temporal changes in their spread and depth quotes. Using individual dealer quote and trade data for a sample of 2,319 stocks, we find that NASDAQ dealers make more frequent revisions in depths than in spreads and the extent of liquidity management is greater for stocks of smaller companies, lower‐priced stocks, and stocks with larger trade sizes and fewer number of transactions. We show that intraday variation in the number of quote revisions follows the U‐shaped pattern, indicating that the extent of liquidity management is greater during the early and late hours of trading than during midday.
