The effect of reference point prices on mergers and acquisitions

Prior stock price peaks of targets affect several aspects of merger and acquisition activity. Offer prices are biased toward recent peak prices although they are economically unremarkable. An offer's probability of acceptance jumps discontinuously when it exceeds a peak price. Conversely, bidder shareholders react more negatively as the offer price is influenced upward toward a peak. Merger waves occur when high returns on the market and likely targets make it easier for bidders to offer a peak price. Parties thus appear to use recent peaks as reference points or anchors to simplify the complex tasks of valuation and negotiation.     

From boom ‘til bust: How loss aversion affects asset prices

This article studies the impact of heterogeneous loss averse investors on asset prices. In very good states loss averse investors become gradually less risk averse as wealth rises above their reference point, pushing up equity prices. When wealth drops below the reference point the investors become risk seeking and demand for stocks increases drastically, eventually leading to a forced sell-off and stock market bust in bad states. Heterogeneity in reference points and initial wealth of the loss averse investors does not change the salient features of the equilibrium price process, such as a relatively high equity premium, high volatility and counter-cyclical changes in the equity premium.     

New empirical evidence on the investment success of momentum strategies based on relative stock prices

This paper provides significant extensions and tests of momentum trading strategies based on relative prices that were first explored by George and Hwang (2004). We develop new momentum strategies based on the ratio of the current stock price to each of five different reference points in past prices: 52-week high, 52-week median, 52-week low, half-year high, and 2-year high. We measure their investment performance on the basis of the Fama and French 3-Factor and Momentum Model (Carhart four-factor model), and further employ the technique of nested trading strategies to measure incremental performance. The strategy based on the ratio of current stock price to its 52-week high price is the most profitable, and its performance is robust when tested over a wide range of financial and economic factors. Our results provide strong new evidence of the investment merits of a momentum trading strategy based on the 52-week high price ratio, and add new weight to challenges to the hypothesis that the stock market is efficient in the semi-strong sense.     

Social connections,reference point and acquisition premium

This paper examines the impact of acquirer-target social connections along with the target 52-week high (Baker et al., 2012) on acquisition premiums. We show that acquisition premium is more sensitive to first-degree connection than the reference point, suggesting that information is the main driving force for determining acquisition premiums. The findings also indicate that connected directors are more likely to favour firms where they hold higher positions and negotiate favourable premiums. Acquirers pay lower premiums when target directors are retained in the new entity. Connected acquirers are also more likely to finance their deals with equity. Overall, this paper provides support to the information flow hypothesis that acquirers with social connections have better access to target information and enhanced bargaining power in negotiations.     

The Moving Average Ratio and Momentum

I show the ratio of the short‐term moving average to the long‐term moving average (moving average ratio, MAR) has significant predictive power for future returns. The MAR combined with nearness to the 52‐week high explains most of the intermediate‐term momentum profits. This suggests that an anchoring bias, in which investors use moving averages or the 52‐week high as reference points for estimating fundamental values, is the primary source of momentum effects. Momentum caused by the anchoring bias do not disappear in the long‐run even when there are return reversals, confirming that intermediate‐term momentum and long‐term reversals are separate phenomena.     

SECURITIES PRICE EFFECTS OF UNIONIZATION LEGISLATION

Prior studies document that firms experience negative stock price effects in response to unionization. We study the economic effects of a radical change in unionization legislation in New Zealand and hypothesize that the stock price effect of unionization is a function of prior unionization status of firms. We provide evidence that legislative events that increase the likelihood of introducing more stringent legislation do not affect stock prices of high‐unionized firms, whereas low‐unionized firms are affected negatively and significantly. Legislative events that signal less stringent unionization legislation result in significant stock price increases for all firms.     

DO INSTITUTIONS PREFER HIGH‐VALUE ACQUIRERS? AN ANALYSIS OF TRADING IN STOCK‐FINANCED ACQUISITIONS

If owners of target shares in a stock‐for‐stock merger perceive the acquirer as overvalued, they should sell their holdings more aggressively to profit before such overvaluation dissipates. We study institutional owners of targets and find that slightly more than half liquidate their shares in stock mergers, consistent with high institutional‐share turnover rates found in the prior literature. However, share retention is higher when valuation measures suggest greater acquirer overvaluation, regardless of whether institutional owners generally prefer growth or value stock. Institutions that prefer large‐cap, growth stock are most enthusiastic about bids from large, high‐valuation acquirers, and substantially increase their stakes in such deals.     

Firm-specific information and the efficiency of investment

In the three-year period following stock market liberalizations, the growth rate of the typical firm's capital stock exceeds its pre-liberalization mean by an average of 4.1 percentage points. Cross-sectional changes in investment are significantly correlated with the signals about fundamentals embedded in the stock price changes that occur upon liberalization. Panel-data estimations show that a 10-percentage point increase in a firm's expected future sales growth predicts a 2.9- to 3.5-percentage point increase in the growth rate of its capital stock. Country-specific changes in the cost of capital drive changes in investment but firm-specific changes in the cost of capital do not.     

Reference point formation by market investors

The disposition effect [Shefrin, H., Statman M., 1985, The disposition to sell winners too early and ride losers too long. Journal of Finance, 40, 777–790], investors’ tendency to sell gaining assets and hold on to loosing assets, relies on the notion of a reference point distinguishing between losses and gains. While literature using aggregated market data documented the existence of such a reference point affecting investors’ decisions, it had not pinpointed it. The main goal of our work is to shed light on the mechanism of reference point formation. We hypothesize that salient events taking place during a stock’s holding period influence investors’ perceptions and make them update the stock’s reference point. Using analysts’ earnings forecasts, stock price data, and firms’ quarterly earnings announcements, we document that company-specific events indeed affect the reference points. We discover that the earnings announcements played a role in reference point formation when they were not anticipated, i.e., when (i) analysts’ earnings forecasts failed to provide accurate predictions; and (ii) the earnings announcements were followed by market price reactions. Moreover, the reference points were affected more profoundly for low market capitalization, high beta firms, pointing that the reference point updating process is more reactive to events when information flow is low and prices are sensitive to market fluctuations. Our results also corroborate the attention hypothesis, i.e., the observation that agents facing numerous alternatives may consider primarily those that have caught their attention.     

Systematic liquidity risk and stock price reaction to shocks

This study examines the relationship between systematic liquidity risk and stock price reaction to large 1‐day price changes (or shocks). We base our analysis on a yearly updated constituents list of the FTSE All share index. Our overall results are consistent with the price continuation hypothesis, which suggests that positive (negative) shocks will be followed by positive (negative) abnormal returns. However, further analysis indicates that stocks with low systematic liquidity risk react efficiently to both positive and negative shocks, whereas stocks with high systematic liquidity risk underreact to both positive and negative shocks. Our results are valid irrespective of various robustness tests such as size of the shock, size of the firm, month‐of‐the‐year and day‐of‐the‐week effects. We conclude that trading on price patterns following shocks may not be profitable, as it involves taking substantial liquidity exposure.     

ARE COMMON STOCKS A HEDGE AGAINST INFLATION?

We test whether U.K. common stocks hedge against inflation using a framework of the tax‐augmented Fisher hypothesis. Aggregate and disaggregate (seven industry groups) monthly data covering 48 years are used. All pairs of stock and retail price indexes are cointegrated. Tests in most cases reveal significant shifts in the cointegrating vectors, and accounting for these shifts improves the precision of the estimates. The point estimates of goods price elasticity are significantly above unity in all but two cases. These findings, though in sharp contrast to most existing findings that report price elasticity of below unity, appear theoretically more plausible because nominal stock returns must exceed the inflation rate to insulate tax‐paying investors.     

Price Performance Following Share‐Repurchase Announcements by Closed‐End Funds

We investigate the price performance of closed‐end funds that announce share‐repurchase programs. Closed‐end funds experience positive average stock‐price reactions to the announcements. The long‐run buy‐and‐hold abnormal returns of repurchasing funds over the subsequent three years are significantly higher than a nonrepurchasing control sample matched by size, type, investment style and geographic diversification. Funds with larger discounts, international funds, equity funds, and funds that announce larger repurchases or frequently announce repurchases, experience more positive stock‐price reactions. Except for larger repurchases, the same characteristics are associated with more positive long‐run buy‐and‐hold returns.     

Does Investment Horizon Matter? Disentangling the Effect of Institutional Herding on Stock Prices

This study finds that, over short horizons, herding by short‐term institutions promotes price discovery. In contrast, herding by long‐term institutions drives stock prices away from fundamentals over the same periods. Furthermore, while the positive predictability of short‐term institutional herding for stock prices is more pronounced for small stocks and stocks with high growth opportunities, the negative association between long‐term institutional herding and stock prices is stronger for stocks whose valuations are highly uncertain and subjective. Finally, we show that the destabilizing effect of institutional herding persistence documented in the recent literature is entirely driven by persistent herding by long‐term institutions.     

Bought deals: The value of underwriter certification in seasoned equity offerings

The bought deal is the predominant method of underwriting SEOs in Canada. Offer prices are set and underwriters commit to purchase offerings several days earlier for bought deals than for firm commitment issues, implying stronger underwriter certification for bought deal issues. Consistent with the certification hypothesis, this study finds a significantly smaller negative stock price reaction around the announcement of bought deals compared to firm commitment issues. Bought deals are further shown to have smaller offer price discounts and smaller underwriting fees, implying superior pricing and thus, higher quality offerings. These findings suggest that investment banks’ underwriting method of choice is informative of issue quality.     

What Does the Corporate Bond Market Know?

Do related markets reflect new information simultaneously? For high‐yield bonds, a large abnormal price decline in a corporation's most liquid bond over a month is followed by an average abnormal stock price decline of ?1.42%. This effect is larger for stocks that have increased in value and for volatile stocks. It is also larger for bonds with high coupons and shorter maturities. These results support the view that high‐yield corporate bonds have an informational edge when news is negative and stock returns are noisy, and add to the growing literature on the substantial lags in price discovery between related markets.     

Why Do Price Limits Exist in Stock Markets? A Manipulation‐Based Explanation

Numerous stock market regulators around the world impose daily price limits on individual stock price movements. We derive a simple model that shows that price limits may deter stock market manipulators. Based on our model's implications, we predict that regulators impose price limit rules for markets where the likelihood of manipulation is high. We present empirical evidence consistent with this hypothesis. Our study is the first to formally propose a manipulation‐based rationale for the existence of price limits in stock markets.     

Acquisitions,Overconfident Managers and Self‐attribution Bias

We examine whether acquisitions by overconfident managers generate superior abnormal returns and whether managerial overconfidence stems from self‐attribution. Self‐attribution bias suggests that overconfidence plays a greater role in higher order acquisition deals predicting lower wealth effects for higher order acquisition deals. Using two alternative measures of overconfidence (1) high order acquisition deals and (2) insider dealings we find evidence supporting the view that average stock returns are related to managerial overconfidence. Overconfident bidders realise lower announcement returns than rational bidders and exhibit poor long‐term performance. Second, we find that managerial overconfidence stems from self‐attribution bias. Specifically, we find that high‐order acquisitions (five or more deals within a three‐year period) are associated with lower wealth effects than low‐order acquisitions (first deals). That is, managers tend to credit the initial success to their own ability and therefore become overconfident and engage in more deals. In our analysis we control for endogeneity of the decision to engage in high‐order acquisitions and find evidence that does not support the self‐selection of excessive acquisitive firms. Our analysis is robust to the influence of merger waves, industry shocks, and macroeconomic conditions.     

Stock price synchronicity and analyst coverage in emerging markets

This paper examines the relation between the stock price synchronicity and analyst activity in emerging markets. Contrary to the conventional wisdom that security analysts specialize in the production of firm-specific information, we find that securities which are covered by more analysts incorporate greater (lesser) market-wide (firm-specific) information. Using the R² statistics of the market model as a measure of synchronicity of stock price movement, we find that greater analyst coverage increases stock price synchronicity. Furthermore, after controlling for the influence of firm size on the lead–lag relation, we find that the returns of high analyst-following portfolio lead returns of low analyst-following portfolio more than vice versa. We also find that the aggregate change in the earnings forecasts in a high analyst-following portfolio affects the aggregate returns of the portfolio itself as well as those of the low analyst-following portfolio, whereas the aggregate change in the earnings forecasts of the low analyst-following portfolio have no predictive ability. Finally, when the forecast dispersion is high, the effect of analyst coverage on stock price synchronicity is reduced.     

The 52-week high momentum strategy in international stock markets

We study the 52-week high momentum strategy in international stock markets proposed by George and Hwang [George, T., Hwang, C.Y., 2004. The 52-week high and momentum investing. Journal of Finance 59, 2145-2176.]. This strategy produces profits in 18 of the 20 markets studied, and the profits are significant in 10 markets. The 52-week high momentum profits exist independently from the Jegadeesh and Titman [Jegadeesh, N., Titman, S., 1993. Returns to buying winners and selling losers: implications for market efficiency. Journal of Finance 48, 65-91.] individual stock and Moskowitz and Grinblatt [Moskowitz, T.J., Grinblatt, M., 1999. Do industries explain momentum? Journal of Finance 54, 1249-1290] industry momentum strategies. These profits do not show reversals in the long run. We find that the 52-week high is a better predictor of future returns than macroeconomic risk factors or the acquisition price. The individualism index, a proxy to the level of overconfidence, has no explanatory power to the variations of the 52-week high momentum profits across different markets. However, the profits are no longer significant in most markets once transaction costs are taken into account.     

Effects of Passive Intensity on Aggregate Price Dynamics

We find that passive intensity (PI), measured by the passive‐linked share of total stock market trading volume, is strongly related to the overall pattern of stock price movements. A one‐standard‐deviation increase in PI is associated with an 8% higher price synchronicity. We further investigate the channels through which this relation is established by separately analyzing its impact on aggregate systematic and idiosyncratic volatility of stock returns. PI has a positive effect on systematic volatility and a negative impact on firm‐specific volatility. Consistent with the effect of passive trading on price dynamics, we find evidence that PI is negatively associated with mutual funds alpha dissimilarity. After controlling for market and idiosyncratic volatility, a one‐standard‐deviation increase in PI corresponds to a 0.20% decrease in fund dissimilarity. Our findings are robust after controlling for various macro and corporate factors known to affect systematic or firm‐specific volatility.
