Information costs and liquidity effects from changes in the FTSE 100 list

Abstract

In this paper we examine the stock price effect of changes in the composition of the FTSE 100 over the time period of 1984–2001. Like the S&P 500 listing studies, we find that the price and trading volume of newly listed firms increases. The evidence is consistent with the information cost/liquidity explanation. This is because investors hold stocks with more available information, implying that they have lower trading costs. This explains the increase in the stock price and trading volume of newly listed stocks to the FTSE 100 List. We find the reverse effect for the deletions from the FTSE 100.     

Price and earnings momentum: An explanation using return decomposition

We explain price and earnings momentum by investigating dynamics of cash flow (CF) news and discount rate (DR) news. We find that before the holding period, winners experience higher DR news than losers, which makes winners display lower ex-ante expected returns than losers. Momentum returns come from the persistently higher CF news for winners as compared to losers both before and during the holding periods. The evidence favors a behavioral explanation that the market incorporates cash flow information too slowly, which drives momentum returns. In addition, we find that the DR news, in particular that of the momentum losers, drives the time-series profitability of momentum strategies. Furthermore, by comparing price momentum with earnings momentum, we show that the relative load on past CF news as compared to past DR news affects long-run portfolio performance.     

News‐Specific Price Discovery in Credit Default Swap Markets

We examine the lead and lag relation between equity and credit default swap (CDS) markets. We find that price discovery in equity markets only leads CDS markets following aggregate positive news and not so following other news. While difficult to reconcile with standard asset pricing theories, asymmetric price adjustment is common in goods markets, arising from intermediary power. We provide an explanation for this asymmetry based on dealers exploiting informational advantages vis‐à‐vis investors with hedging motives. Consistent with this explanation, we find that the patterns we document are related to firm‐level proxies for hedging demand, as well as economy‐wide measures of information asymmetries.     

The Impact of Mispricing and Asymmetric Information on the Price Discount of Private Placements of Common Stock

The price discount on privately placed stock is large and can vary substantially among firms. While earlier studies attribute price discounts on privately placed stock to illiquidity and costs of gathering information, we offer a more complete explanation. We find that firms exhibiting higher overvaluation have significantly larger price discounts in private stock sales. We also find that higher levels of asymmetric information about the issuing firm and about the stock market environment at the time of the private placement cause more pronounced discounts in the offer price. Our analysis also shows that post-issue abnormal returns following private placements are higher when discounts are less pronounced.     

Price‐matching guarantees

Are price‐matching guarantees anticompetitive? We examine the incentives for price‐matching guarantees in markets where information about prices is costly. The conventional explanation of price matching as facilitating cartel pricing finds some theoretical support, but our model provides an additional explanation. A price‐matching guarantee may be a credible and easily understood means of communicating to uninformed consumers that a firm is low priced. The credibility of the signal is assured by the behavior of informed consumers. We contrast the testable implications of our model with those arising from two theories of price matching as anticompetitive, and show that available evidence supports the signalling theory.     

Do managers intentionally use repurchase tender offers to signal private information? Evidence from firm financial reporting behavior

Signaling is the most commonly cited explanation for stock repurchases in the academic literature. Yet, there is little evidence on whether managers intentionally use repurchases as signaling devices. Using a firm's financial reporting behavior to infer managerial intent, we find evidence suggesting that managers intentionally use fixed-price repurchase tender offers to signal undervaluation. In contrast, we find no evidence that managers use Dutch-auction tender offers to signal undervaluation. Instead, firms engaging in Dutch-auction repurchases act as if they are trying to deflate their earnings prior to the repurchases to further reduce the repurchasing price.     

Evidence of oil market price clustering during the COVID-19 pandemic

We use hourly data on opening price, closing price, opening ask price, opening bid price, closing ask price and closing bid price to show that while oil prices are characterized by price clustering behavior, prices tend to cluster on numbers closer to zero than to one. Comparing the pre-COVID-19 sample with the COVID-19 sample, we find that evidence of price clustering is 8% more in the COVID-19 sample. We test the determinants of price clustering and find that as much as 30% of the price clustering behavior can be attributed to the COVID-19 pandemic. Finally, using a simple technical trading strategy, we do not find any evidence that the oil market is profitable in the COVID-19 period.     

The TIPS‐Treasury Bond Puzzle

We show that the price of a Treasury bond and an inflation‐swapped Treasury Inflation‐Protected Securities (TIPS) issue exactly replicating the cash flows of the Treasury bond can differ by more than $20 per $100 notional. Treasury bonds are almost always overvalued relative to TIPS. Total TIPS‐Treasury mispricing has exceeded $56 billion, representing nearly 8% of the total amount of TIPS outstanding. We find direct evidence that the mispricing narrows as additional capital flows into the markets. This provides strong support for the slow‐moving‐capital explanation of arbitrage persistence.     

Initiating coverage,broker reputation and management earnings forecasts in Australia

We examine more than 5000 recommendations made by Australian brokers in the period 1996–2001. We find evidence that initiating recommendations produce greater share price responses than continuing recommendations, particularly for hold, underperform and sell recommendations. We also find evidence that initiating recommendations made by higher‐reputation brokers and those made in the absence of a management earnings forecast attract different share price responses. Finally, we find that share price responses to initiating recommendations, conditional on the market consensus recommendation, are significantly different to continuing recommendations.     

Accruals and price crashes

I investigate the relation between accruals and firm-level price crashes, representing extreme price decreases in weekly returns. I find that high accruals predict a higher price crash probability than low accruals. This finding can be explained by managers’ use of income-increasing accrual estimates to hoard bad news. Once accumulated bad news crosses a tipping point, it is released all at once and results in a price crash. Consistent with this explanation, I find the observed relation to be the strongest for operating assets (the least reliable accrual components). Cross-sectional analyses further support the bad news hoarding explanation.     

On the origin of power-law tails in price fluctuations

We analyse large stock price changes of more than five standard deviations for (i) TAQ data for the year 1997 and (ii) order book data from the Island ECN for the year 2002. We argue that a large trading volume alone is not a sufficient explanation for large price changes. Instead, we find that a low density of limit orders in the order book, i.e. a small liquidity, is a necessary prerequisite for the occurrence of extreme price fluctuations. Taking into account both order flow and liquidity, large stock price fluctuations can be explained quantitatively.     

Capital Structure Theory and REIT Security Offerings

In this paper, we examine the stock price reactions to announcements of new security offerings by Real Estate Investment Trusts (REITs). REITs offer a unique setting in which to study these events because they do not pay taxes at the firm level. Theory suggests that the net tax gain to corporate borrowing is unambiguously negative for a REIT. Contrary to some recent studies, however, we find a positive stock price reaction to debt offerings, while the negative equity-issuance effect is preserved. Further empirical evidence lends support to signalling as the explanation for the positive significant debt-issuance effect.     

Informed trading before analyst downgrades: Evidence from short sellers

This paper studies short-selling prior to the release of analyst downgrades in a sample of 670 downgrades of Nasdaq stocks between 2000 and 2001. We find abnormal levels of short-selling in the three days before downgrades are publicly announced. Further, we show that this pre-announcement abnormal short-selling is significantly related to the subsequent share price reaction to the downgrade, and especially so for downgrades that prompt the most substantial price declines. Our findings are robust to various controls that might also affect short-selling such as pre-announcement momentum, three-day pre-announcement returns, and announcement-day share price. In addition, the results are independent of scheduled earnings announcements, analyst herding, and non-routine events near downgrades. Further evidence suggests that tipping is more consistent with the data than the prediction explanation which posits that short sellers successfully predict downgrades on the basis of public information about firms’ financial health. Finally, we present evidence that downgraded stocks with high abnormal short-selling perform poorly over the subsequent six months by comparison with those with low abnormal short-selling. Overall, our results support the hypothesis that short sellers are informed traders and exploit profitable opportunities provided by downgrade announcements.     

Stock Returns following Large One-Day Declines: Evidence on Short-Term Reversals and Longer-Term Performance

We examine stock returns following large one-day price declines and find that the bid-ask bounce and the degree of market liquidity explain short-term price reversals. Further, we do not find evidence consistent with the overreaction hypothesis. We observe that securities with large one-day price declines perform poorly over an extended time horizon.     

Order flow,dealer profitability,and price formation

We analyze the dynamics of the S&P 500 futures price, finding both short- and long-run effects of order flow on price. While price moves strongly with the order flow in the short-run, the long-run impact is slightly negative, attributable to costly slippage from a hedging propensity in futures markets. We find strong evidence of a state dependence in the relation between price and order flow, using both volume and floor trader income measures as states. We also find that both the long- and short-run impacts of order flow are greater when dealer income is higher.     

What Drives the S&P 500 Inclusion Effect? An Analytical Survey

We present an analytical survey of the explanations—price pressure, downward-sloping demand curves, improved liquidity, improved operating performance, and increased investor awareness—for the increase in stock value associated with inclusion in the S&P 500 Index. We find that increased investor awareness is the primary factor behind the cross-section of abnormal announcement returns. We also find some evidence of temporary price pressure around the inclusion date. We find no evidence that long-run downward-sloping demand curves for stocks, anticipated improvements in operating performance, or increased liquidity are related to the cross-section of announcement or inclusion returns.     

Do the prices of stock index futures in Asia overreact to U.S. market returns?

We extend the overreaction study to interaction of international markets and find that intraday price reversals exist in Asian index futures markets following extreme movement in U.S. market. Profitable opportunities exist after considering transaction cost. We show that the reversal cannot be explained by rational arguments such as risk, liquidity and bid-ask spread. We further observe that a magnitude effect exists. Overreaction is more prominent in the latter period than in the initial period. After calm-down periods, overreaction is greatly reduced. These observations support the explanation that the source of price reversals lies in behavioral biases.     

Some evidence on Ross' resolution irrelevancy hypothesis

This research attempts to discriminate empirically between the predictable events and resolution irrelevancy hypotheses as both pertain to abnormal stock price performance around regular and special proxy statement mailing dates and the related shareholder meeting dates. We find no evidence that these events result in the positive wealth effects suggested by the predictable events hypothesis. We do find evidence of increased idiosyncratic stock price volatility or information flow around special meeting proxy statement mailing dates and special meeting dates. Thus, our evidence supports the resolution irrelevancy hypothesis.     

Price adjustment and exchange rate pass-through

This paper develops a simple theoretical model that can be used to account for the determinants of exchange rate pass-through to consumer prices. While recent evidence has found low estimates of pass-through in many countries, there is little consensus on an explanation for this. Our paper argues that sticky prices represent a key determinant of exchange rate pass-through. We make this argument in two stages. First, holding the frequency of price change constant, we show that our model calibrated to data from low-inflation countries can reproduce the estimates of very low pass-through for these countries. The principal determinant of low pass-through in this case is the slow adjustment of prices. We then extend the model to allow the frequency of price change to be endogenous. Calibrating to a wider set of countries, including both low-inflation and high-inflation countries, we show that our model implies that exchange rate pass-through is increasing in average inflation, but at a declining rate. Performing the identical exercise on the data, we find a striking correspondence between the predictions of the model and those of the data.     

Do mandatory risk factor disclosures reduce stock price crash risk?

We test whether voluntary or mandatory risk factor disclosures (RFDs) in 10-K filings is associated with a reduction in stock price crash risk. We find that the level of mandatory RFDs in 10-K filings is associated with a reduction in stock price crash risk but find no similar relationship for voluntary RFDs. We exploit two exogenous shocks to mitigate endogeneity concerns that remain to be addressed in the literature. We investigate the moderators for this relationship and find the reduction is magnified among firms with higher information asymmetry, higher litigation risk, or better corporate governance. Overall, our findings identify a potential avenue to mitigate stock price crash risk and provide evidence that mandated RFDs contain useful information content and benefit investors.
