Stock repurchases and treasury share sales: Do they stabilize price and enhance liquidity?

Can companies reduce the volatility and increase the liquidity of their stocks by trading them? In the context of the Italian stock market, where companies have far more leeway to sell as well as buy their own stocks than in the U.S., the answer is yes. We examine the effects of trading (open-market share repurchases and treasury shares sales) on liquidity (bid-ask spread) and volatility (return variance). Further, we examine the impact of shareholder approvals of repurchase programs on liquidity and volatility. We find clear evidence that trading increases liquidity and reduces volatility. These results are consistent with our analysis of the motives Italian companies give for making share repurchases.     

Actual Share Reacquisitions in Open-Market Repurchase Programs

Unlike Dutch auction repurchases and tender offers, open-market repurchase programs do not precommit firms to acquire a specified number of shares. In a sample of 450 programs from 1981 to 1990, firms on average acquire 74 to 82 percent of the shares announced as repurchase targets within three years of the repurchase announcement. We find that share repurchases are negatively related to prior stock price performance, suggesting that firms increase their purchasing depending on its degree of perceived undervaluation. In addition, repurchases are positively related to levels of cash flow, which is consistent with liquidity arguments.     

Flexibility in share repurchases: Evidence from UK

Although firms cite flexibility as important when repurchasing shares, we know little about how or why firms vary repurchases. We use an extensive sample of daily repurchase transactions from the United Kingdom to investigate how the number of repurchase days and volumes of shares repurchased change based on several known motivations. We find that stock price changes, liquidity, leverage, takeover activity and earnings per share targets impact share repurchasing patterns. Further, we compare actual repurchases to alternative share accumulation strategies and find that firms utilize flexibility without paying higher costs.     

The effects of ownership and stock liquidity on the timing of repurchase transactions

We analyze detailed monthly data on U.S. open market stock repurchases (OMRs) that recently became available following stricter disclosure requirements. We find evidence that OMRs are timed to benefit non-selling shareholders. We present evidence that the profits to companies from timing repurchases are significantly related to ownership structure. Institutional ownership reduces companies' opportunities to repurchase stock at bargain prices. At low levels, insider ownership increases timing profits and at high levels it reduces them. Stock liquidity increases profits from timing OMRs.     

Economic conditions and the motives for multiple open-market share buybacks

We examine the impact of business conditions on the frequency of share repurchases. The results generally indicate that share repurchase programs are positive and statistically significant in HIGH economic states relative to the other economic states. Segmenting the data into frequency of repurchases, we find evidence suggesting different economic states exert influence on frequent and infrequent but not occasional repurchase programs. Further, we show that firms that institute frequent share repurchasing programs experience stronger returns across different business cycles compared to infrequent and occasional share repurchasers.     

Stock repurchasing and corporate social responsibility

Stock repurchases are controversial. Researchers often view the positive association between free cash flow and the volume of the stock repurchases to be in the shareholders’ interest and the positive association between executive options and stock repurchases to be in the managers’ interest. Using firms’ corporate social responsibility (CSR) ratings as a measure of ethical culture—one that increases the cost of self-serving behavior for managers— we examine whether a firm’s CSR rating is related to its stock repurchase decisions. Although the baseline regression shows a positive association between CSR and repurchases, we find that CSR amplifies the positive association between free cash flow and stock repurchases and lessens the positive association between executive options and stock repurchases. These results indicate that ethical culture might play a role in repurchase decisions: it may encourage repurchases aligned with shareholders’ interests and discourage those primarily in managers’ interest. Furthermore, we also find that high CSR firms are associated with a greater completion rate of announced repurchase programs and receive more favorable stock market reaction to their repurchase announcements.     

Share repurchases and institutional supply

Consistent with the predictions of Brennan and Thakor's (1990) model of shareholder preferences, we find that, on average, institutional shareholders are net sellers during share repurchases. After controlling for liquidity provision and characteristics investing, we find that a one standard deviation increase in share repurchases during a given quarter is associated with a 0.11 standard deviation decrease in institutional investor demand. We estimate that 37% of the inverse relation is attributed to institutional investors executing liquidity provision strategies, 8% is explained by institutions reacting to the investment characteristics signaled by a repurchasing firm. We attribute the majority, 55%, to the information asymmetry between institutions and individual investors. This work is one of the first to exploit the SEC mandate requiring firms to report the actual number of shares they repurchase each quarter, beginning in 2004. Using actual number of shares repurchased, we find evidence of institutional investors increasing their selling as firms increase their repurchasing. This finding is robust to models of endogeneity and autocorrelation in share repurchases and institutional investor trading.     

On the Timing and Execution of Open Market Repurchases

Little is known about the timing and execution of open marketrepurchases. U.S. firms are under no obligation to disclosewhen they are trading, and generally report only quarterly changesin shares outstanding. We use 64 firms' supplementally disclosedrepurchase trading data to provide the first examination ofrepurchase timing and execution. Across the days reported inour sample, firms adopted a variety of execution styles rangingfrom immediate intense repurchasing to delayed and smoothedrepurchasing. We find no clear evidence that repurchases aretimed to coincide with, precede, or follow, days on which informationis released. We benchmark the costs and value of a given repurchaseprogram against naive accumulation strategies achieving thesame terminal portfolio. While there is considerable variationacross the firms, NYSE firms on average beat their benchmarks,whereas NASDAQ firms do not. Finally, we document the liquidityimpact of open market repurchases. We find that repurchasingcontributes to market liquidity by narrowing bid-ask spreadsand attenuating the price impact of order imbalances on dayswhen repurchase trades are completed.     

Accelerated share repurchases

Accelerated share repurchases (ASRs) are credible commitments by firms to repurchase shares immediately. Including an ASR in a repurchase program reduces the flexibility that firms have to alter an announced program in response to subsequent changes in the price and liquidity of its shares, unexpected shocks to cash flow and/or investment, etc. Thus, we investigate whether firms' decisions to include ASRs in their repurchase programs are associated with factors expected to influence the costs of lost flexibility and the benefits of enhanced credibility and immediacy. We find robust evidence consistent with the costs of lost flexibility and the benefits of credibility and immediacy being important determinants of ASR adoption. Additionally, we find that ASR announcements are associated with positive average abnormal stock returns.     

Investment opportunities and share repurchases

We examine the over-investment motivation for share repurchases using a sample of 139 Real Estate Investment Trusts (REITs) between 1996 and 2010. By combining a REIT's property portfolio data with project ROAs from the underlying real estate market, we are able to create a unique measure of the firm's investment opportunity set. Controlling for other possible buyback rationales, we find that poor investment opportunities are related to higher levels of share repurchases. Conditioning on investment opportunities, we find that the level of cash is positively related to repurchases only for low investment opportunity set firms. We also find a negative relationship between share repurchase announcement returns and investment opportunities.     

Cash holdings and share repurchases: International evidence

In this study, we examine the patterns and determinants of share repurchases using firm-level data from seven major countries—Australia, Canada, France, Germany, Japan, the U.K., and the U.S.—over the period 1998–2006. We find that while non-U.S. firms do not repurchase shares as much as U.S. firms do, both U.S. and non-U.S. firms display a common set of share repurchase behaviors. For example, across countries, firms use share repurchases as a flexible means of distributing cash. More importantly, large cash holdings are significantly associated with the amount of share repurchases in all countries. There is evidence that large cash holdings held by repurchasing firms represent excess cash. Firms tend to experience substantial increases in cash holdings prior to share repurchase as a result of reductions in capital expenditures. Overall, our evidence lends support to two hypotheses: (i) firms discharge excess capital to reduce agency conflicts and (ii) firms use repurchases to distribute temporary cash flows.     

Buyback behavior of initial public offering firms

We examine the motives behind the share repurchase decisions of initial public offering (IPO) firms by studying the stock and operating performance after the IPO date. We find that IPO firms that announce repurchases within 3 years of IPO dates exhibit poorer long-run abnormal operating performance than other IPO firms. These IPO firms also experience poorer stock return performance and downward analyst forecast revisions. Moreover, these firms show intensive insider selling transactions after the IPO date. These results for IPO announcing repurchase firms are consistent with the misleading hypothesis, which suggests that these IPO firms mislead investors by announcing repurchases as false signals.     

Controlling shareholders’ opportunistic use of share repurchases

This study examines how share repurchase and dividend policies are influenced by controlling shareholders in an emerging market. We maintain that the controlling shareholders can utilize share repurchase opportunistically, particularly when they exercise voting rights in excess of cash-flow rights. The evidence of Korean firms suggests that the wedge between the voting rights and cash-flow rights positively affects share repurchases but negatively affects cash dividends. We also find that share repurchases are not always supported by operating performances. The results indicate that firms may utilize share repurchases as a means to pursue private benefits of the controlling shareholders. We also document that share repurchases do not substitute for cash dividends, suggesting that share repurchases are not genuine distributions. Furthermore, we find that the wedge of share repurchases reduces firm value. Overall, our results indicate that the controlling shareholders of Korean firms use share repurchases opportunistically rather than strategically.     

Share Repurchases, the Clustering Problem, and the Free Cash Flow Hypothesis

We examine the market reaction to announcements of actual share repurchases, events that cluster both within and across firms. Using a multivariate regression model, we find that the market reacts positively to the events, indicating that these announcements provide additional information to that contained in the initial repurchase intention announcements. Further, the market response is especially favorable for firms with overinvestment problems as measured by Tobin's q , and is not related to signaling costs as measured by the size of the repurchase. Our findings generally support the hypothesis that share repurchases reduce the agency costs of excessive free cash flow .     

Stock repurchases as an earnings management device

We investigate whether firms use stock repurchases to meet or beat analysts’ earnings per share (EPS) forecasts. We identify conditions under which repurchases increase EPS and document the frequency of accretive repurchases from 1988 to 2001. We find a disproportionately large number of accretive stock repurchases among firms that would have missed analysts’ forecasts without the repurchase. The repurchase-induced component of earnings surprises appears to be discounted by the market, and this discount is larger when the repurchase seems motivated by EPS management, although using the repurchase to avoid missing analyst forecasts appears to mitigate some of the negative stock price response.     

An empirical analysis of European stock repurchases

In this paper, we examine the share price effects and determinants of share repurchase programs for French, German, Italian, and British firms. Like US firms, we find that German and Italian share repurchases are met with a positive and significant share price response. However, British repurchase announcements exhibit small positive abnormal returns, and abnormal returns for French share repurchases are insignificantly different from zero, both results being quite different from results found in studies of US firms. We also investigate the determinants of the size of the share repurchase program.Our results indicate support for the Undervaluation Hypothesis and the Takeover Deterrence Hypothesis, and provide partial support for the National Investment Opportunity Set Hypothesis. Our results from our analysis of cumulative abnormal returns are also consistent with the Undervaluation, Takeover Deterrence, and National Investment Opportunity Set Hypotheses. However, we do not find support for the Excess Capital Hypothesis, the Intangibility Hypothesis or the Optimal Leverage Ratio Hypothesis.     

The many facets of privately negotiated stock repurchases

We investigate the causes and consequences of 737 privately negotiated share repurchases in the years 1984–2001. In contrast to the negative announcement returns and positive repurchase premiums reported by past research, we find positive announcement returns and premiums that are not significantly different from zero. Only when we investigate the 60 greenmail events separately do we find results similar to past research. However, for this subsample, we find long-horizon excess returns that are comparable to the average 18% repurchase premium, challenging the widely accepted opinion that managers overpay in greenmail repurchases. Moreover, we find that our understanding of the event improves when we split the non-greenmail repurchases according to the price paid. Repurchases at a premium can be modeled as signals, while other repurchases are mere wealth transfers between the corporation and the selling stockholders, the extent of which is determined by the relative bargaining power of the seller and the repurchasing firm.     

Share repurchases,catering, and dividend substitution

We first extend Baker and Wurgler's (2004a) catering theory of dividends to share repurchases. Consistent with the notion that firms cater to investor demand for share repurchases, we report evidence that the market's time-varying repurchase premium positively affects firms' choice to repurchase shares. Next, we use the catering behavior as a novel framework for testing the dividend substitution hypothesis. Consistent with the notion that managers consider dividends and share repurchases to be substitute payout mechanisms, we find that the dividend premium negatively affects the repurchase choice, whereas the repurchase premium negatively affects the choice to pay dividends.     

Information and Long‐Term Stock Performance Following Open‐Market Share Repurchases

We find that firm managers have private information when they decide on open‐market share repurchases, and that this information is significantly correlated with announcement period and post‐announcement abnormal returns. We further find that long‐term post‐announcement abnormal returns are related to private information differently for firms that actually repurchase shares when compared to firms that announce a repurchase program but do not acquire shares. Our results indicate that managers’ private information is only ambiguously revealed by the repurchase announcement, and that the market waits for the firm's subsequent actions, such as actual repurchase, to further interpret the private information.     

The Takeover Deterrent Effect of Open Market Share Repurchases

This paper examines whether open market share repurchases deter takeovers. We model pre‐repurchase takeover probability as a latent variable and examine its impact on the firm's decision to repurchase shares. Given specification tests reject the Tobit model, we turn to the censored quantile regression method of Powell (1986, Journal of Econometrics 32, 143–155). We find a significantly positive relation between open market share repurchases and takeover probability, and we reconcile empirical findings in previous studies that contradict predictions. Repurchase activity is inversely related to firm size, consistent with smaller firms having greater information asymmetry, and is related to temporary, but not permanent, cash flows.
