Takeover vulnerability and the credibility of signaling: The case of open-market share repurchases

There is debate in the literature focuses on whether open market repurchases can be taken as a signal of stock undervaluation. This research argues that takeover pressures before a repurchase announcement can be a credible signal of undervaluation. The empirical results indicate that repurchasing firms with a higher probability of takeover experience greater announcement effects, improvements in operating performance and long-run abnormal return, positive forecast revisions by financial analysts, and enhanced agreement between management and shareholders. These findings suggest that takeover probability and open-market share repurchases appear to constitute a double-signal for conveying stock undervaluation to the market.     

REIT Open-Market Stock Repurchases and Profitability

This study examines whether the announcement of real estate investment trust (REIT) open-market stock repurchase programs contain information content about future operating performance over the period 1990–2001. We find no evidence that REIT stock buybacks are positively related to the operating performance. In fact, the operating performance of our sample REIT firms peak at the repurchase announcement year and deteriorate in the years following the announcement of share repurchases. Nevertheless, the sample REITs show higher levels of post-repurchase operating performance when compared to those of the pre-repurchase period. Additionally, our regression analysis shows that changes in future operating performance can explain the positive announcement effect.     

What do insiders know? Evidence from insider trading around share repurchases and SEOs

We examine the nature of information contained in insider trades prior to corporate events. Insiders' net buying increases before open market share repurchase announcements and decreases before seasoned equity offers. Higher insider net buying is associated with better post-event operating performance, a reduction in undervaluation, and, for repurchases, lower post-event cost of capital. Insider trading also predicts announcement returns and long-term abnormal returns following events. Overall, our results suggest that insider trades before corporate events contain information about changes both in fundamentals and in investor sentiment.     

The Optimal Timing of Open Market Stock Repurchases

Using a continuous-time real options approach we determine the conditions under which a value-maximizing company would conduct an open market stock repurchase to exploit the undervaluation of shares. We find the optimal timing of such repurchases as well as the optimal amount a company should repurchase and analyze how it depends on market parameters. Obtaining the announcement returns from the authorization of stock repurchases from our model allows us to derive testable empirical implications.     

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.     

Is the market underreacting or overreacting to open market share repurchases? A UK perspective

Using UK open market repurchases, we reject the market underreaction hypothesis and the market overreaction hypothesis proposed by Ikenberry et al. (1995) and Peyer and Vermaelen (2009), respectively. The evidence suggests that the UK market reacts slowly to actual repurchases made by value firms. UK repurchases on average do not suffer from share undervaluation prior to the announcement. Value firms perform just as well as glamour firms during the authorisation period but outperform glamour firms significantly 2 years following the announcement. It turns out that value firms repurchase over 6% more shares than glamour firms during the authorisation period.     

Information content of repurchase signals: Tangible or intangible information?

The outperformance of repurchasing firms with a high book-to-market (B/M) ratio is usually explained by investors’ undervaluation of the firm’s past performance. However, several studies suggest that the underestimation of future intangible value may explain the high return associated with the share repurchase. To better understand the actual information content of repurchases, I decompose the B/M ratio into past tangible information and future intangible information and find that repurchase signals an undervaluation of the intangible return. In addition, I investigate several potential proxies for intangible information—R&D expenses, intangible assets, and future operating performance. My results show that intangible information signals the undervaluation of future operating performance.     

Insider Trading and Firm Performance Following Open Market Share Repurchase Announcements

The long‐run performance of equity securities subsequent to announcements of open market repurchases (OMR) remains a contentious topic. In this paper we propose the “dichotomous expectations hypothesis” which posits that insider trading following share repurchase announcements reveals private information concerning the future operating performance of announcing firms. In particular, insider abnormal purchases (abnormal sales) should predict an improvement (decline) in operating performance that leads to higher (lower) long‐run stock returns. Our hypothesis offers a credible economic link between insider trading and subsequent long‐run stock performance through the intervening variable of operating performance. The empirical results show consistency with this linkage.     

Insider trading and share repurchases: Do insiders and firms trade in the same direction?

Signaling undervaluation is often considered a primary motive for repurchasing stock, but insider trading activity by repurchasing firms is not always consistent with undervaluation. Net insider buying and selling are both more frequent in quarters when firms are repurchasing non-trivial amounts of stock, with the odds of observing a repurchase the highest in quarters with net insider selling. In multinomial logit models, share repurchases associated with net insider selling are positively related to illiquidity, option exercises by insiders, and pre-repurchase returns and negatively correlated with industry-adjusted book to market ratios when compared to other repurchases. Hence, repurchases when insiders are selling stock are more likely done to support share prices or avoid dilution and are less likely undervaluation signals. We find that insider trades either validate or mitigate the undervaluation signal of the repurchase. Abnormal returns of repurchasing firms with net insider buying versus net insider selling in a given quarter are significantly higher for the quarter immediately after the repurchase and the three subsequent years. For repurchases accompanied by net insider selling, abnormal returns are negligible after only one year.     

Capital structure,equity mispricing,and stock repurchases

We evaluate motives for share repurchases using a unified framework where a firm has a target capital structure and has equity that can be mispriced. We document that capital structure adjustments are a value-increasing motive for repurchases and that the extent to which adjusting capital structure through a repurchase creates value depends on the undervaluation of the firm. Underlevered and undervalued firms enjoy the greatest economic gains from a repurchase, as evidenced by the stock price reaction to the repurchase announcement, and these firms are more likely to announce a share repurchase program.     

Share price performance following actual share repurchases

Using unique actual daily share repurchase data from Hong Kong, this paper investigates share price performance surrounding and following actual share repurchases. It is found that repurchasing firms buy back shares following price drops, suggesting that they behave opportunistically when implementing actual share repurchases. On average, the initial 3-day market response to actual repurchases is about 0.43%. Repurchasing firms do not seem to exhibit superior abnormal performance over long horizons when they make actual share repurchases. However, the price performance of repurchasing firms varies across firm size and market–book value ratios, and shows a clear and consistent pattern. The market responds the most favorably to repurchases that are made by small and value (high book-to-market value) firms. Over a long horizon, there is some evidence that repurchases made by value firms show superior performance. The three-year buy-and-hold abnormal return, which is measured against a portfolio of control firms that are matched by size and book-to-market value ratios, is over 20%. At least, repurchases made by high book-to-market value firms, for which undervaluation is more likely to occur, can benefit long-term shareholders.     

The Relative Signalling Power of Dutch-Auction and Fixed-Price Self-Tender Offers and Open-Market Share Repurchases

We compare three forms of common stock repurchases. Dutch-auction self-tender offers and open-market share repurchase programs are weaker signals of stock undervaluation than fixed-price self-tender offers. The price increase from buyback announcements is greater when insider wealth is at risk, greater following negative net-of-market stock returns, and unrelated to prior market returns. Buyback announcement returns are also increasing in the fraction of shares sought, which is consistent with both signalling and an upward-sloping supply curve for stock.     

A comprehensive examination of the wealth effects of recent stock repurchase announcements

The main purpose of this paper is to examine the wealth effect of stock repurchase announcements using a sample of 11,862 repurchase programs announced during 1994–2007. The results of several recent industry surveys indicate that managerial motivations for repurchasing shares may have changed in recent years. To better understand the reasons for repurchasing shares we classify our sample in various ways—by year, by the method used for repurchasing shares, and by the stated purpose of the program. We find that the median size of firms repurchasing shares has increased dramatically recently, and concomitantly, the announcement returns have declined. Signaling undervaluation of share prices appears to become less important than previously assumed. While smaller firms signal undervaluation using open market repurchases, tender offers are chosen to enhance shareholder values by other means.     

Stock repurchases with legal restrictions. Evidence from Spain

This paper analyses the consequences of legal restrictions on the volume of shares firms can repurchase. Results suggest that the imposition of a limit on the volume of common stock favours the use of open market repurchases (OMRs) compared to other methods of repurchase such as tender offer repurchases (TORs) and Dutch auctions (DAs). The positive share abnormal returns around both announcements of open market buybacks and sellbacks in the full sample suggest that they are basically used to change the ownership structure of the firm in a consistent way with the convergence of interest hypothesis. The positive abnormal stock returns around open market repurchases, which are significantly different to the negative ones around sellbacks, when there are no changes in ownership structure also indicates the existence of a signalling and free cash flow effects.     

Legal Institutions,Ownership Concentration,and Stock Repurchases Around the World: Signal Mimicking?

One of the central puzzles of signaling theory is how to assess signal quality, in particular the potential for signal mimicking. Our study provides evidence of signal mimicking in the context of stock repurchases. Employing an ex-ante proxy for the likelihood of mimicking stock repurchases and data on open market stock repurchases from 30 countries, we find that long-term operating and market performance following stock repurchases improve less for suspected mimicking firms. This finding contradicts the conventional characterization that managers use stock repurchases to signal undervaluation and enhanced future performance. We find that mimicking firms have smaller capital investments, need greater external financing, buy back fewer shares, and issue more new shares (and/or resell more treasury shares) in the year of the repurchase. Our analysis further shows that mimicking is more likely in countries with weak investor protections and in firms with higher ownership concentration. Further, mimicking associated with concentrated ownership is mitigated in countries with stronger investor protections and by the adoption of International Financial Reporting Standards (IFRS). Altogether, our findings provide evidence of signal mimicking in stock repurchases in international data that is influenced by market, ownership, legal, and financial reporting characteristics of countries.     

Stock price behavior surrounding stock repurchase announcements: Evidence from Japan

This paper examines stock price behavior surrounding announcements of stock repurchases made by Japanese firms from 1995 to 1998. Our analysis shows that, much as in the case of the U.S. markets, stock prices in Japan go up in response to stock repurchase announcements. We also find that there is no significant difference between the market reaction to the announcement for intention of repurchase execution and the market reaction to the announcement of an article alteration to allow stock repurchases. On the other hand, there is a significant difference in the pre-announcement period returns motivating these two announcements. While a large decline in stock price will motivate a firm to execute a stock repurchase, a smaller price decline will motivate a firm to merely alter its articles of association to allow future repurchases.     

Open-Market Stock Repurchase and Stock Price Behavior When Management Values Real Investment

This paper provides a simple explanation of open‐market stock repurchases and the stock price behavior surrounding them. There is ex ante asymmetry of information with regard to the private benefits that corporate managers can attain from real investments. In our model, open‐market repurchase announcements reveal information about the managers' private benefits when real investment opportunities are unprofitable in terms of firm values. This study differs from previous studies in that we show that announcements of open‐market repurchase programs can be believable without the restriction that the announcements are commitments. Empirically, the model simultaneously predicts that a stock price will drop prior to an open‐market repurchase announcement and will rise in response to the announcement. These predictions are consistent with stylized facts.     

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.     

OPEN MARKET REPURCHASES: THE VALUE FROM BUYING SHARES AT A DISCOUNT

This article shows that share repurchase announcements create value for shareholders when the shares of the industrial firm sell at a discount from the value of the underlying assets, even when shareholders and managers share full information about the firm's prospects and the firm's operating performance is not expected to improve. The value created by capturing the discount on the repurchased shares is a function of only two variables: the percentage discount prior to the announcement and the proportion of shares to be repurchased.
For a sample of 100 companies selling below net asset value, the authors report that the excess stock returns surrounding their announcements of open market repurchases are (significantly) positively associated with the authors' estimates of the value captured from buying shares at a discount. Moreover, the stock market's response to repurchase announcements by companies that are selling at a discount is considerably more positive than to announcements by firms selling at a premium.     

THE INTRA-INDUSTRY EFFECTS OF OPEN MARKET SHARE REPURCHASES: CONTAGION OR COMPETITIVE?

We examine the extent to which announcements of open market share repurchase programs affect the valuation of competing firms in the same industry. On average, although firms announcing open market share repurchase programs experience a significantly positive stock price reaction at announcement, portfolios of rival firms in the same industry experience a significant and contemporaneous negative stock price reaction. This suggests that perceived changes in the competitive positions of the repurchasing firms occur at the expense of rival firms and dominate any signals of favorable industry conditions. Thus, the competitive intra-industry effects of open market repurchases outweigh any contagion effects. In addition, cross-sectional tests indicate that these competitive effects are more pronounced in industries characterized by a lower degree of competition and less correlation between the stock returns of the repurchasing firm and its rivals.
