Stock Splits: Evidence from Mutual Funds

Mutual fund splits occur in high-priced funds after unusually high returns. Split factors are related to the deviation of a fund's price from the mean of all fund prices. Post-split prices are below the mean of other funds' prices. Post-split numbers of shareholders and assets do not increase compared with funds having similar rates of asset growth. However, I find evidence that mutual fund splits bring per account shareholdings back up to normal levels. I argue that signaling, liquidity, and tick size theories do not apply to mutual fund splits.     

Underreaction to Self-Selected News Events: The Case of Stock Splits

An emerging literature looking at self-selected, corporate newsevents concludes that markets appear to underreact to news.Recent theoretical articles have explored why or how underreactionmight occur. However, the notion of underreaction is contentious.We revisit this issue by focusing on one of the most simpleof corporate transactions, the stock split. Prior studies thatreport abnormal return drifts subsequent to splits do not appearto be spurious, nor a consequence of misspecified benchmarks.Using recent cases, we report a drift of 9% in the year followinga split announcement. We consider fundamental operating performanceas a source of the underreaction and find that splitting firmshave an unusually low propensity to experience a contractionin future earnings. Further, analysts' earnings forecasts arecomparatively low at the time of the split announcement andrevise sluggishly over time. Together these results are consistentwith the notion of market underreaction to the information incorporate news events.     

Stock Splits: Prior and Subsequent Price Relationships

Although it has long been recognized that a stock split merely changes the packaging of an investor's claim to earnings, there is widespread belief in the financial community that the split confers some substantive benefits on stockholders. This paper describes an empirical investigation of the effect of split action on stock price. The split action was found to have an insignificant effect, even at a 10% level, on changes in market price over the 12 month period surrounding the split.     

Stock Splits and Stock Dividends: Why,Who, and When

This study investigates empirically why firms split their stock or distribute stock dividends and why the market reacts favorably to these distributions. The findings suggest that stock splits are mainly aimed at restoring stock prices to a “normal range.” Some support can also be found for the oft-mentioned signalling motive of stock splits. Stock dividends are altogether different from stock splits, and they appear to be a decreasing phenomenon. The clue to stock dividend distributions may lie in their perceived substitution for relatively low cash dividends.     

Rationality of Stock Splits: The Target-Price Habit Hypothesis

The question of why firms exercise stock splits has inspired research for some time. Signalling and optimal trading range hypotheses are possible explanations for stock splits. This paper considers the sociological aspects of maintaining a stable target-price habit. It argues that one of the principal reasons for stock splits is to conform to the market norm, which is established by mutual reinforcement among financial analysts, managers, and investors. Models based on economic reasons alone do not fully explain the rationality of stock splits.     

REIT Stock Splits and Liquidity Changes

This study examines the motive of stock splits made by REITs. We find that REIT liquidity increases after the split announcement. However, the increase in liquidity is limited to days around the split announcement. After the ex-date, the liquidity tends to revert back to the pre-split level. We find that the positive market reaction around the announcement date is positively related to the change in short-term liquidity but not to the change in long-term liquidity. The announcement effect is also not correlated with future changes in operating performance. Overall, our results suggest that REITs split their share to attract investors’ attention rather than to signal or to improve trading liquidity in the long run.     

REIT Stock Splits and Market Efficiency

An analysis of real estate investment trust (REIT) stock splits is presented. Evaluation of the initial reaction to split REITs supports efficient market pricing where REITs generate statistically significant positive announcement date returns, no statistically significant record date returns, and muted ex-date returns. In the long-term, split REITs do not consistently out perform benchmark portfolios over one-year, two-year, and three-year periods. REITs split subsequent to a substantial run up in stock price and to improve the position of their post split stock price relative to the stock price of the typical REIT.     

The Performance of Long-run Stock Returns Following Issues of Public and Private Debt

This study uses a balance sheet-based method to identify both public and private debt issues. This feature is important because there have been no studies of the information content of private debt issues, while private debt is substantially more prevalent than public debt. We find no abnormal returns following straight debt issues. However, convertible debt issuers under-perform the market on the order of 50 to 70 percent in the following five years. In pursuit of explanations, we find that convertible debt issues signal a deterioration of future profitability, which accounts for at least part of the stock price underperformance.     

Stock Splits, Tick Size, and Sponsorship

A traditional explanation for stock splits is that they increase the number of small shareholders who own the stock. A possible reason for the increase is that the minimum bid-ask spread is wider after a split and brokers have more incentive to promote a stock. I document a large number of small buy orders following Nasdaq and NYSE/AMEX splits during 1993 to 1994. I also find strong evidence that trading costs increase, and weak evidence that costs of market making decline following splits. This is consistent with splits acting as an incentive to brokers to promote stocks.     

The Differences Between Stock Splits and Stock Dividends: Evidence on the Retained Earnings Hypothesis

Abstract:  This paper investigates stock dividends and stock splits on the Copenhagen Stock Exchange (CSE), which is of interest because several of the more recent explanations for a stock market reaction can be ruled out. The main findings are that the announcement effect of stock dividends as well as stock splits is closely related to changes in a firm's payout policy, but that the relationship differs for the two types of events. A stock dividend implies an increase in nominal share capital and hence a decrease in retained earnings. Firms announcing stock dividends finance growth entirely by debt (explaining the need for an increase in nominal share capital) and retained earnings. Basically all firms announcing a stock dividend with a split factor of less than two can also afford to increase their total cash dividends permanently, at least proportionally to the increase in share capital, leading to a significant announcement effect of 4.23%. Firms announcing a stock dividend with a split factor of two or more also increase total cash dividends permanently, but less than proportionally to the increase in share capital. This leads to an insignificant announcement effect of 0.08%. These findings support a retained earnings/signaling hypothesis. For stock splits, no separate announcement effect was found when a firm's payout policy was controlled for. This lends support to the idea that a stock split per se is a cosmetic event on the CSE and is also consistent with the fact that making a stock split on the CSE is virtually cost free.     

Picking Your Tick: Toward a New Theory of Stock Splits

Thanks to stock splits, the average nominal share price has been amazingly stable in the United States. The average NYSE share price has fluctuated within the $30 to $40 range since the late 1930s—a period in which most consumer prices have increased by a factor of 10 and the S&P index has risen over 1,500%. Why has this nominal price been so stable when every other price has increased so much? And why do typical stock prices vary so greatly among different countries? For example, the median nominal stock price ranges from about $2 in Hong Kong and $7 in the U.K., to $103 in France and over $600 in Switzerland. The author's recent research suggests that typical stock prices vary across countries in ways that reflect primarily differences in how markets in each country set their “tick” rules—the rules governing the minimum price variation that can occur in a stock (in the U.S., for example, the tick was recently reduced from $1/8 to $1/16). Companies, on average, appear to respond to the resulting differences in tick size by adjusting the number of their shares outstanding so that the tick size relative to the nominal share price remains relatively constant. In fact, a tick size equal to about 25 basis points of the median share price “appears to be a universal norm” across global markets. This article explores how and why a company might wish to affect the relative tick size for its stock by splitting—and, in so doing, it suggests a “new theory” of stock splits. The theory also suggests that the optimal tick size for any given company will vary according to its size, visibility, and riskiness.     

Stock Splits as a Manipulation Tool: Evidence from Mergers and Acquisitions

We document that acquiring firms are more likely than nonacquiring firms to split their stocks before making acquisition announcements, especially when acquisitions are financed by stock and when the deals are large. Our findings support the hypothesis that some acquiring firms use stock splits to manipulate their equity values prior to acquisition announcements. Using earnings quality as a proxy for firms' intention to manipulate, we find that acquirers with low earnings quality (i.e., acquirers that are more likely to use stock splits to manipulate their stock values) have lower long‐run stock returns compared with their benchmarks, especially when the deals are financed with stock. In contrast, acquirers with high earnings quality do not show that pattern. Our evidence complements and extends the findings in the literature that some acquirers manipulate their stock prices before stock‐swap acquisitions. This study suggests that target shareholders should use information such as earnings quality and stock splits to discriminate among acquirers and ensure that exchanges are conducted on fair terms.     

Reverse Stock Splits,Institutional Holdings,and Share Value

We show that both the number of institutional investors and the percentage of shares that are held by institutional investors increase significantly after reverse splits with a presplit price lower than $5 and a target price higher than $5. This effect is larger than for other comparable reverse splits. These results suggest institutional holdings are affected by the prudent‐person rule and reverse splits are used by firms to alleviate this constraint. We also show that an increase in institutional holdings that results from reverse splits is associated with an increase in share price.     

Tick Size,Share Prices,and Stock Splits

Minimum price variation rules help explain why stock prices vary substantially across countries, and other curiosities of share prices. Companies tend to split their stock so that the institutionally mandated minimum tick size is optimal relative to the stock price. A large relative tick size provides an incentive for dealers to make markets and for investors to provide liquidity by placing limit orders, despite its placing a high floor on the quoted bid-ask spread. A simple model suggests that idiosyncratic risk, firm size, and visibility of the firm affect the optimal relative tick size and thus the share price.
