The impact of mandatory IFRS reporting on institutional trading costs: Evidence from Australia

This study examines the impact of mandatory International Financial Reporting Standards (IFRS) on the market quality of the Australian Securities Exchange (ASX) 200 constituent stocks. Using traditional metrics that are consistent with prior literature (i.e., bid‐ask spreads), the first stage analysis confirms that stock liquidity has improved. However, when the analysis is extended to consider the trading costs incurred by market participants (i.e., execution shortfall), results suggest liquidity has not changed significantly. The paper utilizes rich unique datasets that contain detailed trade information, and findings are robust after controlling for trade difficulty and market conditions. In the era of High Frequency Trading (HFT) and occurrences of ‘fleeting’ liquidity, this paper provides some evidence that while IFRS may have enhanced ‘visible’ bid‐ask spreads, tangible liquidity for market participants, particularly global institutional investors, has not improved significantly.     

OPEN MARKET STOCK REPURCHASE PROGRAMS AND LIQUIDITY

In this paper I examine the behavior of bid and ask spreads and depths around announcements of open market stock repurchase programs. For a sample of 195 announcements from 1988 to 1990, I find statistically significant evidence of a small decline in spreads and no evidence of a shift in depths following the announcement date. Results are similar for a subsample of firms experiencing post-announcement declines in the number of shares outstanding. I conclude that open market repurchase programs as used recently do not adversely affect market liquidity.     

NUMBER OF TRANSACTIONS AND VOLATILITY: AN EMPIRICAL STUDY USING HIGH‐FREQUENCY DATA FROM NASDAQ STOCKS

Our empirical evidence based on transactions data of a sample of Nasdaq stocks indicates that trades of large firms are related to the proxies of marketwide and firm‐specific information. For large firms, an increase in the number of trades seems to have a beneficial effect on liquidity as measured by bid‐ask spreads. On the other hand, trades of small and medium firms are associated with firm‐specific information and are not related to marketwide information. For small and medium firms, the frequency of trades is positively associated with bid‐ask spreads, apparently because of the adverse information content of trades.

Intraday Patterns in the Cross‐section of Stock Returns

Motivated by the literature on investment flows and optimal trading, we examine intraday predictability in the cross‐section of stock returns. We find a striking pattern of return continuation at half‐hour intervals that are exact multiples of a trading day, and this effect lasts for at least 40 trading days. Volume, order imbalance, volatility, and bid‐ask spreads exhibit similar patterns, but do not explain the return patterns. We also show that short‐term return reversal is driven by temporary liquidity imbalances lasting less than an hour and bid‐ask bounce. Timing trades can reduce execution costs by the equivalent of the effective spread.     

Stock Splits and Liquidity: The Case of the Nasdaq-100 Index Tracking Stock

In an attempt to disentangle the signaling effect from the liquidity effect of stock splits, I examine the liquidity changes following the two‐for‐one split of the Nasdaq‐100 Index Tracking Stock. Since there can be no signaling with an index stock split, any difference between pre‐ and postsplit trading may be driven by liquidity but not signaling effects. I find that though the postsplit relative bid‐ask spread is higher and daily turnover is unchanged, the frequency, share volume, and dollar‐volume of small trades all increased after the split, indicating that the split improved liquidity for small trade‐sizes.     

Decimals And Liquidity: A Study Of The Nyse

Using a carefully constructed matched sample of control (nondecimal) stocks, we isolate the effects of decimalization for a sample of NYSE‐listed common stocks trading in decimals. We find that the quoted depth as well as the quoted and effective bid‐ask spreads declined significantly following decimalization. Additionally, both the number of trades and trading volume declined significantly. Stock return volatilities display an initial increase but a decline over the longer term, probably as traders become more comfortable in their new milieu.     

Mandatory Disclosure,Voluntary Disclosure,and Stock Market Liquidity: Evidence from the EU Bank Stress Tests

We use the EU stress tests and the Eurozone sovereign debt crisis to study the consequences of supervisory disclosure of banks’ sovereign risk exposures. We test the idea that a mandatory one‐time disclosure induces an increase in voluntary disclosures about sovereign risk in the following periods and, through the shift in the voluntary disclosure equilibrium, increases the liquidity of banks’ shares. First, we find that the timing and content of different mandatory disclosure events helps explain the levels of stress‐test banks’ voluntary disclosures about sovereign risk. Second, although the bid‐ask spreads of stress test participants generally increased after the mandatory stress test in 2011, our results suggest that the decrease in market liquidity is entirely attributable to those stress‐test participants that did not commit to voluntarily maintaining the disclosures of sovereign risk exposure.     

Analyst Coverage,Market Liquidity and Disclosure Quality: A Study of Fair-value Disclosures by European Real Estate Companies Under IAS 40 and IFRS 13

Disclosures in notes have been criticized by practitioners for being unwieldy and contributing little to the quality of the financial information. This study presents evidence on the association between disclosure quality, analyst following and liquidity in the real estate sector. More specifically, we study the disclosure of the methods and significant assumptions applied in determining fair values of investment properties under IAS 40 and IFRS 13. We find that disclosure quality is significantly higher under IFRS 13. Furthermore, we show that the quality is associated with analyst following and bid-ask spreads. However, the improved disclosures following the adoption of IFRS 13 are not associated with any significant positive economic consequences. This result indicates that the revised disclosure requirements in IFRS 13 did not solve any market imperfections.     

Executive Network Centrality and Stock Liquidity

We examine the relationship between stock market liquidity and the network centrality of firm executives. We find that firms whose executive officers are more central in the network of executives have narrower bid‐ask spreads. We use an exogenous network centrality shock of executive turnover and report that liquidity improves after firms hire executives with greater centrality. We present evidence that improved liquidity is attributable to efficient information flows around executives in more advantageous network positions.     

Market liquidity and institutional trading during the 2007–8 financial crisis

This paper shows that institutional sell-side herding increased bid–ask spreads and liquidity risk during the 2007–8 financial crisis. Such an impact on liquidity is most pronounced in firms with large numbers of institutions that sold the same stocks, that is, have correlated trades. For the same reason, we find institutional investors with a dedicated, buy-and-hold, investment style to be the least likely to herd; their trading activity did not affect stock market liquidity during the crisis. Our results are robust to alternative explanations, different test specifications and consistent with recent theories highlighting the negative impact of institutional trading activity on market liquidity during a crisis.     

The Volatility of Bid‐Ask Spreads

This study tests whether the volatility of bid‐ask spreads is positively related to expected returns. After controlling for market‐risk factors, we find that the average risk‐adjusted excess return for stocks in the highest spread volatility quintile is around 50 basis points per month. In a variety of multivariate tests, we find robust evidence of a return premium associated with spread volatility that is both statistically significant and economically meaningful. Our results are robust to controls for a variety of stock characteristics, different tick‐size regimes, and other measures of liquidity volatility.     

Eliminating the 20-F reconciliation from IFRS to U.S. GAAP: Short-term and long-term liquidity effects

This paper examines the effects of the SEC’s 2008 decision to no longer require foreign private issuers using IFRS and trading on U.S. exchanges to reconcile their financial statements to U.S. GAAP. Extant research has found conflicting results using short event windows, while studies using longer event windows have found limited capital market impact from eliminating the reconciliation. Motivated by the SEC’s interest in understanding how disclosure rules impact market liquidity, we examine changes in effective bid-ask spreads, the price impact of trades, and quoted depth around 20-F filing dates for a sample of foreign private issuers. We find that effective spreads increase more around 20-F filing dates for filers using IFRS than for filers using U.S. GAAP, suggesting the 20-F report is more informative for filers using IFRS. We then find, in a subsample of filers using IFRS, that the increase in effective spreads for IFRS firms around 20-F filing dates is directly related to the magnitude of differences in book values between IFRS and U.S. GAAP. In sum, our results suggest a loss of useful information after the SEC’s rule change.     

Market behaviour around bankruptcy announcements: evidence from the Australian Stock Exchange

The corporate distress literature to date has largely focused on the predictive power of accounting variables ( Altman, 2001 ). Following previous literature, this study examines the relevance of abnormal stock returns in discriminating between failed and non‐failed firms (e.g. Clark and Weinstein, 1983; Shumway, 2001). Our results confirm the findings of previous literature that investors in failed firms typically incur substantial negative stock returns leading up to failure announcements. However, in contrast to prior research we do not find evidence of an announcement effect (i.e. negative stock returns on the event day itself or the day preceding). We also document evidence that the bid‐ask spreads of failed firms widen substantially up to 7 months prior to failure, indicating the likelihood of significant information asymmetries across investors in failed firms.     

Transparency,Liquidity, and Valuation: International Evidence on When Transparency Matters Most

We examine the relation between firm‐level transparency, stock market liquidity, and valuation across countries, focusing on whether the relation varies with a firm's characteristics and economic environment. We document lower transaction costs and greater liquidity (as measured by lower bid‐ask spreads and fewer zero‐return days) for firms with greater transparency (as measured by less evidence of earnings management, better accounting standards, higher quality auditors, more analyst following, and more accurate analyst forecasts). The relation between transparency and liquidity is more pronounced in periods of high volatility, when investor protection, disclosure requirements, and media penetration are poor, and when ownership is more concentrated, suggesting that firm‐level transparency matters more when overall investor uncertainty is greater. Increased liquidity is associated with lower implied cost of capital and with higher valuation as measured by Tobin's Q. Finally, a mediation analysis suggests that liquidity is a significant channel through which transparency affects firm valuation and equity cost of capital.     

The Impact of the Reduction in Tick Increments in Major U.S. Markets on Spreads,Depth, and Volatility

This study presents an analysis of the impact of the introduction of quotes in sixteenths of a dollar on the AMEX, Nasdaq, and NYSE in mid-1997 on select market characteristics such as spreads, effective spreads, quoted depth, and volume. The findings of the study document reductions in the bid-ask spread, effective spread, and a statistically significant increase in the number of quotes. Interestingly, we find that liquidity, as measured by the total depth at the bid and ask, declines significantly on the AMEX and NYSE, but increases on the Nasdaq. Trading volume increases on the NYSE, but remains unchanged for the AMEX and Nasdaq. We also find that the proportion of even-increment quotes is a relevant factor affecting percentage spreads for Nasdaq both before and after and for the NYSE only after the change in quoting increments.     

Does good corporate governance reduce information asymmetry around quarterly earnings announcements?

We examine the relationship between the quality of corporate governance and information asymmetry in the equity market around quarterly earnings announcements. We use the change in market liquidity (i.e., bid–ask spreads and depths) around the announcements as a proxy for information asymmetry. We use principal components analysis to identify three factors, board independence, board structure and board activity, that capture the information in the eight individual corporate governance variables we examine. We then use ordinary least squares and two-stage least squares to estimate the relations between market liquidity changes and the following four explanatory variables: directors’ and officers’ percentage stock holdings, board independence, board structure, and board activity. Our results indicate that changes in bid–ask spreads at the time of earnings announcements are significantly negatively related to board independence, board activity, and the percentage stock holdings of directors and officers. We also find that depth changes are significantly positively related to board structure, board activity, and directors’ and officers’ percentage stock holdings. Our results are consistent with the hypothesis that firms with higher levels of corporate governance have lower information asymmetry around quarterly earnings announcements.     

Subsidizing Liquidity: The Impact of Make/Take Fees on Market Quality

Facing increased competition over the last decade, many stock exchanges changed their trading fees to maker‐taker pricing, an incentive scheme that rewards liquidity suppliers and charges liquidity demanders. Using a change in trading fees on the Toronto Stock Exchange, we study whether and why the breakdown of trading fees between liquidity demanders and suppliers matters. Posted quotes adjust after the change in fee composition, but the transaction costs for liquidity demanders remain unaffected once fees are taken into account. However, as posted bid‐ask spreads decline, traders (particularly retail) use aggressive orders more frequently, and adverse selection costs decrease.     

Liquidity, analysts, and institutional ownership

In this paper, we investigate the empirical relationship between institutional ownership, number of analysts following and stock market liquidity. We find that firms with larger number of financial analysts following have wider spreads, lower market quality index, and larger price impact of trades. However, we find that firms with higher institutional ownership have narrower spreads, higher market quality index, and smaller price impact of trades. In addition, we show that changes in our liquidity measures are significantly related to changes in institutional ownership over time. These results suggest that firms may alleviate information asymmetry and improve stock market liquidity by increasing institutional ownership. Our results are remarkably robust to different measures of liquidity and measures of information asymmetry.     

Impact of MiFID II tick-size regime on equity markets—Evidence from the LSE

This study investigates the impact of MiFID II on the London Stock Exchange. We find that a tick-size reduction leads to lower bid–ask spreads, lower trade values, reduced cost of trading at and beyond the best bid-offer, an acceleration of quote updates, an increase in aggressive trades and a reduction in price impact. Increased tick size widens spreads and increases trading costs. Step functions reveal that liquidity adjusts opposite to the tick change. To determine if impacts are proportional, we identify potential functions that predict cost changes with tick updates, implying that traders adjust their trade sizes according to the new tick levels.     

The determinants of the price impact of block trades: further evidence

This article extends previous literature which examines the determinants of the price impact of block trades on the Australian Stock Exchange. As previous literature suggests that liquidity exhibits intraday patterns, we introduce time of day dummy variables to explore time dependencies in price impact. Following theoretical developments in previous literature, the explanatory power of the bid–ask spread, a lagged cumulative stock return variable and a refined measure of market returns are also examined. The model estimated explains approximately 29 per cent of the variation in price impact. Block trades executed in the first hour of trading experience the greatest price impact, while market conditions, lagged stock returns and bid–ask spreads are positively related to price impact. The bid–ask spread provides most of the explanatory power. This suggests that liquidity is the main driver of price impact.
