Clifford Asness [25] Extrapolation is projecting historical data into the future on the same basis; if prices have risen at a certain rate in the past, they will continue to rise at that rate forever. The argument is that investors tend to extrapolate past extraordinary returns on investment of certain assets into the future, causing them to overbid those risky assets in order to attempt to continue to capture those same rates of return.

Overbidding on certain assets will at some point result in uneconomic rates of return for investors; only then the asset price deflation will begin.

When investors feel that they are no longer well compensated for holding those risky assets, they will start to demand higher rates of return on their investments.

Herding[ edit ] Another related explanation used in behavioral finance lies in herd behaviorthe fact that investors tend to buy or sell in the direction of the market trend.

Investment managers, such as stock mutual fund managers, are compensated and retained in part due to their performance relative to peers.

Journal of Financial Economics 81(1): Efficient Tests of Stock Return Predictability of Stambaugh (), Lewellen () finds some evidence for predictability with valuation ratios. A difficulty with understanding the rather large literature on predictability is the sheer. Despite extensive literature on stock return predictability, no definite conclusion has yet emerged as to whether stock returns are predictable with any financial macroeconomic variablesor Although.

Taking a conservative or contrarian Financial ratios and stock return predictability pdf as a bubble builds results in performance unfavorable to peers.

This may cause customers to go elsewhere and can affect the investment manager's own employment or compensation. The typical short-term focus of U.

In attempting to maximize returns for clients and maintain their employment, they may rationally participate in a bubble they believe to be forming, as the risks of not doing so outweigh the benefits. A person's belief that they are responsible for the consequences of their own actions is an essential aspect of rational behavior.

An investor must balance the possibility of making a return on their investment with the risk of making a loss — the risk-return relationship.

A moral hazard can occur when this relationship is interfered with, often via government policy. Bush on 3 October to provide a Government bailout for many financial and non-financial institutions who speculated in high-risk financial instruments during the housing boom condemned by a story in The Economist titled "The worldwide rise in house prices is the biggest bubble in history".

Other causes of perceived insulation from risk may derive from a given entity's predominance in a market relative to other players, and not from state intervention or market regulation. A firm — or several large firms acting in concert see carteloligopoly and collusion — with very large holdings and capital reserves could instigate a market bubble by investing heavily in a given asset, creating a relative scarcity which drives up that asset's price.

Because of the signaling power of the large firm or group of colluding firms, the firm's smaller competitors will follow suit, similarly investing in the asset due to its price gains.

When the large firm, cartel or de facto collusive body perceives a maximal peak has been reached in the traded asset's price, it can then proceed to rapidly sell or "dump" its holdings of this asset on the market, precipitating a price decline that forces its competitors into insolvency, bankruptcy or foreclosure.

The large firm or cartel — which has intentionally leveraged itself to withstand the price decline it engineered — can then acquire the capital of its failing or devalued competitors at a low price as well as capture a greater market share e. Other possible causes[ edit ] Some regard bubbles as related to inflation and thus believe that the causes of inflation are also the causes of bubbles.

Others take the view that there is a "fundamental value" to an assetand that bubbles represent a rise over that fundamental value, which must eventually return to that fundamental value.

There are chaotic theories of bubbles which assert that bubbles come from particular "critical" states in the market based on the communication of economic factors. Finally, others regard bubbles as necessary consequences of irrationally valuing assets solely based upon their returns in the recent past without resorting to a rigorous analysis based on their underlying "fundamentals".

Experimental and mathematical economics[ edit ] Bubbles in financial markets have been studied not only through historical evidence, but also through experimentsmathematical and statistical works.

Smith, Suchanek and Williams [7] designed a set of experiments in which an asset that gave a dividend with expected value 24 cents at the end of each of 15 periods and were subsequently worthless was traded through a computer network.

They found instead that prices started well below this fundamental value and rose far above the expected return in dividends. The bubble subsequently crashed before the end of the experiment. This laboratory bubble has been repeated hundreds of times in many economics laboratories in the world, with similar results.

The existence of bubbles and crashes in such a simple context was unsettling for the economics community that tried to resolve the paradox on various features of the experiments. To address these issues Porter and Smith [30] and others performed a series of experiments in which short selling, margin trading, professional traders all led to bubbles a fortiori.

Much of the puzzle has been resolved through mathematical modeling and additional experiments. In particular, starting inGunduz Caginalp and collaborators [22] [31] modeled the trading with two concepts that are generally missing in classical economics and finance.

First, they assumed that supply and demand of an asset depended not only on valuation, but on factors such as the price trend. Second, they assumed that the available cash and asset are finite as they are in the laboratory. Utilizing these assumptions together with differential equations, they predicted the following: An epistemological difference between most microeconomic modeling and these works is that the latter offer an opportunity to test implications of their theory in a quantitative manner.International Journal of Financial Studies (ISSN ) is an international, peer-reviewed, scholarly open access journal on financial market, instruments, policy, and management research published quarterly online by MDPI..

Analysis showed that financial ratios have significant power of predictability for forecasting returns of stock and they predict future stock return of Pakistani torosgazete.com sample 2 but a negative one in . An economic bubble or asset bubble (sometimes also referred to as a speculative bubble, a market bubble, a price bubble, a financial bubble, a speculative mania, or a balloon) is trade in an asset at a price or price range that strongly exceeds the asset's intrinsic value.

It could also be described as a situation in which asset prices appear to be based on implausible or inconsistent views. predictability, I examine the time-series relations among expected return, risk, and book-to- market. Consistent with rational pricing, book-to-market captures significant time-variation in.
