Who moves stock prices? Monthly evidence
Existing evidence using US data shows a simultaneous covariability between a stock's price and quarterly flows into and out of the stock by institutional investors. In this paper we use date on monthly changes in holdings by all investor groups at the Oslo Stock Exchange to shown that the quarterly effects in US data is concentrated within a month. We see a clear positive relation between monthly net flows into a stock by institutions and foreigners and the stock's return. We find no evidence of any effects the next month, providing evidence against the hypothesis that the US quarterly results are due to within-quarter feedback. Such feedback effects must be of less than one month duration. We show that offsetting net inflows by mutual funds and foreigners are net outflows by individual and nonfinancial investors. The interesting question is which of these groups are active in pushing prices. While we can not empirically distinguish which of the various investor groups is reacting, we argue that the most reasonable story is that institutions and foreign investors are the active parties, since the prices move in the direction of these groups' trades. The lack of next-month feedback (price reversals) is consistent with prices moving toward fundamentals.Asset Prices; Investor Groups; Mutual Funds; Herding; Feedback.
The (implicit) cost of equity trading at the Oslo Stock Exchange. What does the data tell us?
We empirically investigate the costs of trading equity at the Oslo Stock Exchange in the period 1980--2008. We show the time series evolution of different measures of (implicit) trading costs: bid/ask spreads, the Roll(1984) measure and the Lesmond et al (1999) measure. We find a clear time variation in these measures, with estimated trading costs much lower in the late eighties and nineties than in the early nineties and just after 2000. The cost of trading has sunk in recent years, but not dramatically compared to earlier periods.Market Microstructure; Trading costs
The diversification cost of large, concentrated equity stakes. How big is it? Is it justified?
While the hypothesis that ownership concentration can affect the value of a company has seen a lot of empirical study, little light has been shed on a complementary problem, that these concentrated owners have a cost of their position due to an undiversified portfolio. Using a unique data set of the actual diversification of all Norwegian equity owners, we show that the largest owners of a corporation in fact have very undiversified equity portfolios, and that such owners have significant costs to their concentrated portfolios. At the level of risk of a benchmark portfolio, if they were to move from their present portfolio composition in risky assets to a well diversified portfolio, their returns would have increased by about 13 percentage points in annual terms. We ask whether this cost can be explained by estimated benefits of ownership concentration (private benefits), and show that extant estimates of private benefits are too low to offset our cost estimates.Portfolio diversification; Large equity owners; Costs and benefits of equity ownership concentration; Private benefits.
Liquidity and Asset Pricing: Evidence on the Role of Investor Holding Period
We use data on actual holding periods for all investors in a stock market over a 10-year period to investigate the links between holding periods, liquidity, and asset returns. Microstructure measures of liquidity are shown to be important determinants of the holding period decision of individual investors. Average holding periods differ across different investor types. Turnover is an imperfect proxy for holding period. While both turnover and spread are related to stock returns, holding period is not.Market microstructure; Holding period; duration
The information content of market liquidity: An empirical analysis of liquidity at the Oslo Stock Exchange
We investigate the information content of aggregate stock market liquidity and ask whether it may be a useful realtime indicator, both for financial stress, and real economic activity in Norway. We describe the development in a set of liquidity proxies at the Oslo Stock Exchange (OSE) for the period 1980-2008, with particular focus on crisis period 2007 through 2008, showing how market liquidity and trading activity changed for the whole market as well as for individual industry sectors. We also evaluate the predictive power of market liquidity for economic growth both in-sample and out-of-sample.Liquidity; Business Cycles; Financial crisis; Economic Activity
Patterns of Corporate Ownership: Insights from a unique data set
Using a data base which is exceptionally rich and accurate by international standards, this paper quantifies a wide range of ownership structure characteristics for all Oslo Stock Exchange firms in the period 1989–1997. Overall, we find that their ownership structures differ remarkably from those of other European firms. We speculate that a socialdemocratic rule and strong legal protection of stockholder rights may explain why the personal investment in Norwegian listed firms is so limited (low direct ownership), why the largest owner is so small (low concentration), and why the other major owners are so large (flat power structure). Our findings raise two questions about the viability of corporate governance systems in general. The first is whether delegated monitoring carried out by state bureaucrats and corporate managers is an effective disciplining mechanism. The second question is whether low ownership concentration produces strong managers and weak owners or whether the flat power structure facilitates joint monitoring by owners who are individually weak, but collectively strong.
Empirical Tests of Models of Catastrophe Insurance Futures
The authors empirically investigate models of insurance futures derivatives contracts. In the fall of 1993 the Chicago Board of Trade (CBOT) started trading a contract designed to scrutinize catastrophic risk, which is currently done in the reinsurance markets. There are obvious advantages to trading on organized exchanges (standardization, liquidity, much reduced credit risk, etc.) as opposed to OTC markets. There has so far been little academic on these contracts. In this paper we look at the price history for the first two years within the context of a pricing model of Aase [1995]. This paper was presented at the Financial Institutions Center's May 1996 conference on "
The ownership structure of repurchasing firms
This paper provides an examination of the ownership structure in Norwegian firms that announced repurchase plans during the period 1999 through 2001, as well as for groups of these firms conditional on whether they actually executed repurchases or not. By using detailed information on various ownership variables that can be related to corporate governance mechanisms, the paper also examines whether the propensity for firms to announce a repurchase program depends on the ownership composition. Some interesting patterns are found which are consistent with models where firms with potentially the highest agency problems use repurchases to mitigate agency costs. However, a high insider ownership in these firms may also suggest that asymmetric information, shareholder expropriation and entrenchment may also be motivations for why firms repurchase shares.Stock repurchases, ownership structure, corporate governance
What factors affect the Oslo Stock Exchange?
This paper analyzes return patterns and determinants at the Oslo Stock Exchange (OSE) in the period 1980--2006. We find that a three-factor model containing the market, a size factor and a liquidity factor provides a reasonable fit for the cross-section of Norwegian stock returns. As expected, oil prices significantly affect cash flows of most industry sectors at the OSE. Oil is, however, not a priced risk factor in the Norwegian stock market. As the case in many other countries, we find that macroeconomic variables affect stock prices, but since we find only weak evidence of these variables being priced in the market, the most reasonable channel for these effects is through company cash flows.Stock Market Valuation; Asset Pricing; Factor Models; Generalized Method of Moments
