Financial ratios and stock return predictability pdf

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.

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. The bubble subsequently crashed before the end of the experiment.

While many studies of market data have shown a rather minimal trend effect, the work of Caginalp and DeSantis [32] on large scale data adjusts for changes in valuation, thereby illuminating a strong role for trend, and providing the empirical justification for the modeling.

The asset flow equations have been used to study the formation of bubbles from a different standpoint in [33] where it was shown that a stable equilibrium could become unstable with the influx of additional cash or the change to a shorter time scale on the part of the momentum investors.

Others take the view that there is a "fundamental value" to an assetand that bubbles represent a rise Financial ratios and stock return predictability pdf that fundamental value, which must eventually return to that fundamental value.

Second, they assumed that the available cash and asset are finite as they are in the laboratory. This opens up the possibility of comparison between experiments and world markets.

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".

Unsourced material may be challenged and removed. First, they assumed that supply and demand of an asset depended not only on valuation, but on factors such as the price trend. 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.

Experimental and mathematical economics[ edit ] Bubbles in financial markets have been studied not only through historical evidence, but also through experimentsmathematical and statistical works. Overbidding on certain assets will at some point result in uneconomic rates of return for investors; only then the asset price deflation will begin.

While many studies of market data have shown a rather minimal trend effect, the work of Caginalp and DeSantis [32] on large scale data adjusts for changes in valuation, thereby illuminating a strong role for trend, and providing the empirical justification for the modeling.

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.

Much of the puzzle has been resolved through mathematical modeling and additional experiments. When price collars were used to keep prices low in the initial time periods, the bubble became larger.

Stages of an economic bubble[ edit ] According to the economist Charles P. 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.

Kindleberger, the basic structure of a speculative bubble can be divided into 5 phases: 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".

For example, the flow of savings from Asia to the U. 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.

In particular, starting inGunduz Caginalp and collaborators [22] [31] modeled the trading with two concepts that are generally missing in classical economics and finance.

Since the parameters can be calibrated with either market, one can compare the lab data with the world market data. Kindleberger, the basic structure of a speculative bubble can be divided into 5 phases: A moral hazard can occur when this relationship is interfered with, often via government policy.

For example, in the housing bubble of the s, the housing prices were unusually high relative to income.

This laboratory bubble has been repeated hundreds of times in many economics laboratories in the world, with similar results. Stages of an economic bubble[ edit ] According to the economist Charles P.

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. Taking a conservative or contrarian position as a bubble builds results in performance unfavorable to peers.

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. Rationalizing borrowing, lending and purchase decisions based on expected future price increases rather than the ability of the borrower to repay.

Economic bubble

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.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. The Low Beta Anomaly: A Decomposition into Micro and Macro Effects Malcolm Baker* Brendan Bradley Ryan Taliaferro September 13, Abstract Low beta stocks have offered a combination of low risk and high returns.

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.
