Differential shareholder wealth and volume effects surrounding private equity placements in New Zealand

Private equity placements in New Zealand exhibit a strong positive relationship between abnormal announcement returns and the price at which shares are placed. The relationship suggests that placement price conveys important information regarding firm quality and value. This is significant as the New Zealand market has different regulations governing private equity placements compared to other countries. For example, private placement purchasers in New Zealand can buy shares at substantial discounts and immediately sell on-market without disclosing these trades to the market for a period of at least 5 days. Private placements issued at a premium exhibit a permanent positive impact on firm value. In contrast, those placed at a discount experience negative announcement returns and show a significant run-down in returns following the announcement. Private placements spark a large increase in trading activity in the 5 days following an announcement and the increase is particularly strong for those placed at a discount. We also find that companies that privately place equity in New Zealand are typically low book to market, thinly traded stocks. Therefore, the immediate returns available to purchasers of discounted shares may reflect fair compensation for these risks.     

Asymmetric information consolidation and price discovery: Inferring bad news from insider sales

Due to the paucity of sources of negative firm‐specific information, US capital markets have more difficulty identifying and incorporating bad news into stock prices than they do good news. Even though insider selling is a potentially important proxy for undisclosed bad news, researchers have difficulty ex ante identifying information‐based sales due to an inability to separate liquidity‐motivated from information‐based insider trades. We hypothesize that when insiders in multiple firms sell shares of one firm in which they are insiders and at the same time buy shares of other insider portfolio firms, the sale is more likely to be information‐based, since the proceeds are reinvested. Conversely, when an insider sells one firm without purchasing others or sells multiple insider firms the sale is likely liquidity‐motivated. We find that insider sales identified as information‐based using this algorithm are followed by significant negative abnormal returns. Information‐based sales are also more likely to be associated with delistings, earnings declines and earnings restatements. Analysts are also more likely to revise their earnings forecasts downwards for these firms. It is thus possible to ex ante identify insider sales with information content. Our results will be of interest to investors and also to regulators designing insider trading rules.     

Overnight block trades in the Korean stock market

We examine the characteristics of overnight block trades in the Korean stock market from 2004 to 2015. We find that the discount on the offering price is negatively related to the number and return volatility of shares, the offering price is higher for firm-commitment contracts than for best-effort contracts, the discount level is lower for larger deal values under best-effort contracts, commission fee rates and fees are more pronounced under firm-commitment contracts, and a deal's uncertainty is related to the firm's contract choice. The incentives of sellers and investment banks are aligned unless sellers face an informational disadvantage.     

Impacts of trades in an error-correction model of quote prices

In this paper we analyze and interpret the quote price dynamics of 100 NYSE stocks stratified by trade frequency. We specify an error-correction model for the log difference of the bid and the ask price with the spread acting as the error-correction term, and include as regressors the characteristics of the trades occurring between quote observations, if any. From this model we are also able to extract the implied model for the spread and the mid-quote. We find that short duration and medium volume trades have the largest impacts on quote prices for all one hundred stocks. Further, we find that buys have a greater impact on the ask price than on the bid price, while sells have a greater impact on the bid price than on the ask price. Both buys and sells increase spreads in the short run, but in the absence of further trades, the spreads mean revert. Trades have a greater impact on quotes for the infrequently traded stocks than for the more actively traded stocks.     

What Drives Shareholder Reaction and Wealth Effect in Block Trades? Evidence from the Warsaw Stock Exchange

The main objective of this article is to present the determinants of shareholder reaction to block trades and their wealth effect on the Warsaw Stock Exchange. The positive abnormal returns obtained for the entire sample indicate that block trades create shareholder value. Shareholders reacted positively to block trades without a control transfer in the Polish market, and their reaction was stronger than in the US market. Abnormal returns of block trades concluded at a discount were twice as high as those for the entire sample. Moreover, cross-border block trades had a negative impact on shareholder value creation, as did financial investors as an acquirer. However, cumulative average abnormal returns (CAARs) were driven up by the relative power of minority shareholders (ocean) prior to the transaction. The absolute size of the block acquired by an investor was also observed to have a positive impact on price rises and abnormal returns.     

Permanent trading impacts and bond yields

We analyse four years of transaction data for euro-area sovereign bonds traded on the MTS electronic platforms. In order to measure the informational content of trading activity, we estimate the permanent price response to trades. We not only find strong evidence of information asymmetry in sovereign bond markets, but also show the relevance of information asymmetry in explaining the cross-sectional variations of bond yields across a wide range of bond maturities and countries. Our results confirm that trades of more recently issued bonds and longer maturity bonds have a greater permanent effect on prices. We compare the price impact of trades for bonds across different maturity categories and find that trades of French and German bonds have the highest long-term price impact in the short maturity class, whereas trades of German bonds have the highest permanent price impact in the long maturity class. More importantly, we study the cross-section of bond yields and find that after controlling for conventional factors, investors demand higher yields for bonds with larger permanent trading impact. Interestingly, when investors face increased market uncertainty, they require even higher compensation for information asymmetry.     

IPO Trading without Market Makers or Underwriter Price Support

We investigate the trading behavior and liquidity supply of Chinese initial public offerings (IPOs) that trade in an order‐driven market system with pure limit order books where no market makers or price support is allowed. We find large trades and quoted depths dominate the first day of trading, but this pattern quickly reverses as small trades and quoted depths are more prevalent on subsequent trading days. Quoted depths are positively related to the number of shares offered in the IPO and trade size, but are negatively related to underpricing. Trade size and transaction immediacy are positively related, and large and positive (negative) order imbalance is associated with more aggressive buys (sells). Finally, long‐run performance is not related to initial order imbalance. Overall, our results suggest that despite underwriters not participating in the IPO aftermarket, liquidity provision evolves very quickly and price discovery is immediately reflected in prices.     

Trade size clustering and the cost of trading at the London Stock Exchange

For the London Stock Exchange, this paper investigates differences in trading costs between market maker (off-book) and order book trades, in the context of clustering in trade sizes and prices. We report several substantial findings. Even after controlling for differences in trade size, the realised spread measure is lower for off-book trades. For the order book, trade size clustering is not associated with differences in transaction costs nor with differences in the information content of trades. For the off-book market, trades in clustered (popular) sizes carry significantly more information than non-clustered trades. Despite the significant differences in the price impact estimates between the order book and off-book, we show that traders placing large orders off-book are still better off than trading via the order book as they benefit from a large discount from the current midpoint price. Additionally, we highlight that price and size clustering tend to occur simultaneously rather than being substitutes in this market setting.     

Portfolio Disclosures and Year-End Price Shifts

Commercial paper sells at an extra discount if it matures in the next calendar year but Treasury bills do not. The discount is apparent in downward price shifts before the year-end, and upward price shifts at the turn of the year that are significantly correlated with the simultaneous returns to small stocks, and that cannot reflect tax-loss selling. Cross-sectional and time-series tests on prices, as well as low of funds evidence on trades by institutional investors, indicate that both the debt and equity patterns reflect agency problems related to portfolio disclosures.     

Competition among Trading Venues: Information and Trading on Electronic Communications Networks

This paper explores the competition between two trading venues, Electronic Communication Networks (ECNs) and Nasdaq market makers. ECNs offer the advantages of anonymity and speed of execution, which attract informed traders. Thus, trades are more likely to occur on ECNs when information asymmetry is greater and when trading volume and stock‐return volatility are high. ECN trades have greater permanent price impacts and more private information is revealed through ECN trades than though market‐maker trades. However, ECN trades have higher ex ante trading costs because market makers can preference or internalize the less informed trades and offer them better executions.     

The Price Impacts of Open Market Repurchase Trades

Abstract:  This paper analyzes a database of 60,000+ individual repurchase trades from the Toronto Stock Exchange. The average intraday price impact of repurchase trades is negative, since, because of execution rules, 60% are seller-initiated. Prices fall less following repurchase than matched non-repurchase trades—there is an abnormal price impact. We find evidence consistent with two hypotheses: repurchases provide price support, and the market learns that the shares are undervalued. Consistent with the latter, we find that repurchasing companies have superior timing. Share prices show abnormal losses (gains) before (after) the repurchase trades. We find no significant market reaction to the mandatory public disclosure of the trade details.     

Information shares in the US Treasury market

This paper highlights the previously neglected role of the futures markets in US Treasury price discovery. The estimates of 5- and 10-year GovPX spot market information shares typically fail to reach 50% from 1999 on. The GovPX information shares for the 2-year contract are higher than those of the 5- and 10-year maturities but also decline after 1998. Relative bid-ask spreads, number of trades, and realized volatility are statistically significant and explain up to 21% of daily information shares. In roughly 1/4 of cases when public information is released, the futures market gains information share, but macroeconomic announcements rarely explain information shares independently of liquidity.     

Earnings Announcements, Asymmetric Information, Trades and Quotes

This paper empirically analyses trades and quotes around the times of 37 earnings announcements in the Paris Bourse. We find that trading volume is larger on announcement days, spreads are wider after announcements, and the permanent positive (resp. negative) price impact of purchases (sales) is greater around announcements. While the findings pertaining to the spread and the permanent impact of trades are consistent with the view that earnings announcements correspond to an increase in information asymmetries, the result that trading volume is larger suggests that other effects are at work.     

Insider trading,future earnings,and post-earnings announcement drift

This paper examines the association between insider trading prior to quarterly earnings announcements and the magnitude of the post-earnings announcement drift (PEAD). We conjecture and find that insider trades reflect insiders’ private information about the persistence of earnings news. Thus, insider trades can help investors better understand and incorporate the time-series properties of quarterly earnings into stock prices in a timely and unbiased manner, thereby mitigating PEAD. As predicted, PEAD is significantly lower when earnings announcements are preceded by insider trading. The reduction in PEAD is driven by contradictory insider trades (i.e., net buys before large negative earnings news or net sells before large positive earnings news) and is more pronounced in the presence of more sophisticated market participants. Consistent with investors extracting and trading on insiders’ private information, pre-announcement insider trading is associated with smaller market reactions to future earnings news in each of the four subsequent quarters. Overall, our findings indicate insider trading contributes to stock price efficiency by conveying insiders’ private information about future earnings and especially the persistence of earnings news.     

The Value of Control and the Costs of Illiquidity

We develop a search model of block trades that values the illiquidity of controlling stakes. The model considers several dimensions of illiquidity. First, following a liquidity shock, the controlling blockholder is forced to sell, possibly to a less efficient acquirer. Second, this sale may occur at a fire sale price. Third, absent a liquidity shock, a trade occurs only if a potential buyer arrives. Using a structural estimation approach and U.S. data on trades of controlling blocks of public corporations, we estimate the value of control, blockholders' marketability discount, and dispersed shareholders' illiquidity‐spillover discount.     

Asymmetry in Stock Returns Following Block Trades on the Australian Stock Exchange: A Note

A number of recent US. studies have examined the price impact of large (block) trades using intraday data. A major finding is that the price movement following block trades continues upwards following purchases but reverses following sales. This asymmetry in price behaviour, which suggests that block sellers pay a liquidity premium while block buyers do not, has been described as 'intriguing' and a 'key puzzle'. The purpose of this note is to determine whether the phenomenon exists on the Australian Stock Exchange. Evidence consistent with the 'puzzling' asymmetry is shown to exist when returns are measured from the block trade until the close of trade. Contrary to US. findings, which have shown that prices appear to reverse following both block purchases and sales in transaction time analysis, the asymmetry in price behaviour is also demonstrated to exist in transaction returns for the ASX. All results are found to be robust to a number of research design innovations and data partitions.     

Daily institutional trades and stock price volatility in a retail investor dominated emerging market

We examine the short-run dynamic relation between daily institutional trading and stock price volatility in a retail investor-dominated emerging market. We find a significantly negative relation between volatility and institutional net trading that is mainly due to the unexpected institutional trading. The price volatility–institutional trade relation differs for institutional buys and institutional sells, and for small and large stocks. Institutional investors herd-trade in large stocks, but do not systematically engage in positive-feedback trading. We argue that the net impact of informational and noninformational institutional trades determines the relation between volatility and institutional trading, and that the relation is negative when informational trading by institutions prevails.     

Predictable behavior, profits, and attention

Stocks in the Shanghai market that hit upper price limits typically exhibit three characteristics: high returns, high volumes, and news coverage. We show that these price limit events attract investors' attention. Attention-grabbing events lead active individual investors to buy stocks they have not previously owned. Consistent with lowering investor search costs, events that affect a few (many) stocks lead to increased (decreased) buying. Upper price limit events coincide with initial price increases followed by statistically significant price mean reversion over the following week. Rational traders (statistical arbitrageurs) profit in response to attention-based buying. Smart traders accumulate shares on date t, sell shares on date t + 1, and earn a daily average profit of 1.16%. We show the amount they invest predicts the degree of attention-based buying by individual investors. We end by decomposing individual investor trades in order to estimate losses attributable to behavioral biases.     

Price impact of block trades: the curious case of downstairs trading in the EU emissions futures market

Using high-frequency data from the European Climate Exchange (ECX), we examine the determinants of price impact of €21 billion worth of block trades during 2008–2011 in the European carbon market. We find that wider bid-ask spreads and volatility are characterised by a smaller price impact. Larger levels of price impact are more likely to occur during the middle of the trading day, specifically the four-hour period between 11 a.m. and 3 p.m., than during the first or final hours. Purchase block trades induce a relatively smaller price impact on price run-up, while sell block trades exhibit a larger price impact on price run-up. We conclude that block trades on the ECX induce less price impact than in equity or conventional futures markets, and that a significant proportion of the effects contradict findings on block trades in those markets; thus, we provide the first evidence of the curious bent to block trading in the European Union emissions trading scheme.     

Block versus nonblock trading patterns

We investigate the relationship between the number of block (20,000 shares) and nonblock (<5,000 shares) trades over the trading day and across exchanges. In general, for each day of the week, the ratio increases from the first to the second period, declines through the period ending at 3:30 p.m., and increases for the last 30-minute period. Periods with increased small trading activity experience a more than proportionate increase in block trades. Differences across exchanges in the intraday pattern of block trades in relation to smaller trades are reported.
