SMB stands for "Small [market capitalization] Minus Big" and HML for "High [book-to-market ratio] Minus Low"; they measure the historic excess returns of small caps over big caps and of value stocks over growth stocks.
There are different ways how market efficiency can be achieved. The most famous include: However, it has been shown that letting the market to work on its own does not always lead to desirable outcomes. Efficiency and equilibrium in competitive markets Market efficiency can be achieved in competitive market by using demand and supply curve.
The intersection of the demand and supply curve is the point where market equilibrium occurs.
This situation implies that marginal benefit equals marginal cost, what is a necessary circumstance for economic efficiency. Pareto efficiency Another way how to judge the extent of government intervention is provided by Pareto efficiency.
Marginal social benefit represents only one particular change that induces a gain to society, while the marginal social costs stands for the cost of the change.
Consequently, there is a market efficiency because if any change occurs it does not induce any net gain. There are three main core conditions for Pareto efficiency which are also useful for analysis of economic efficiency: Exchange efficiency[ edit ] All the produced goods ought to be distributed to the individuals for whom they are most valuable.
Consequently, there does not occur a situation where trade or exchange could make two individuals better off. Trade is feasible when marginal rate of substitution of two individuals differs. However, in the case of exchange efficiency, the same marginal rate of substitution for all individuals is required.
For competitive markets to reach exchange efficiency, each individual is supposed to always face the same price. To analyze production efficiency of any economy, there are usually used isocost and isoquants lines. Production efficiency is reached in competitive markets when firms face the same price.
Market Cap is the sum of the market value of each company assigned to the applicable GICS sector or industry. Market value or capitalization is calculated by multiplying the number of common shares outstanding by the market price per share at the end of each trading day. the future performance of stocks, the ERP incorporates expectations of future stock market returns, which are not directly observable. At the end of the day, any model of the ERP is a model of investor. STOCK MARKET VOLATILITY: AN EVALUATION Their research tells us that higher volatility corresponds to a higher probability of a declining market. Lower volatility corresponds to a higher probability of a rising market. The VIX is used as a of stock returns peaked at over 20 percent in Other developed countries experienced similar.
Thus, for market to be efficient, we need to take into account individuals' preferences and what is technically possible. Analysis is feasible using the production possibilities schedule which should lead to the highest level of utility.
Utility can be achieved when the indifference curve and the production possibilities schedule are tangent.
In the case of product mix efficiency it is expected that marginal rate of substitution is equal to the marginal rate of transformation where the marginal rate of transformation expresses the slope of the production possibilities schedule.
It is common for competitive market to have product mix efficiency.OptionMetrics research data is used in studies by academia and practitioners. See a list of academic papers using OptionMetrics data for volatility metrics.
the implied volatilities of call and put options on individual equities has strong predictive power for aggregate stock market returns. This predictability is inconsistent with a. Stock market uncertainty and the relation between stock and bond returns 1 Introduction It is well known that stock-market volatility exhibits substantial variation over time.
In this paper, we seek to demonstrate the predictability of stock market returns and explain the nature of this return predictability. To this end, we introduce investors with different investment horizons into the news-driven, analytic, agent-based market model developed in Gusev et al.
[Algo. Finance, , 4, 5–51]. This heterogeneous framework enables us to capture dynamics at multiple.

With their ability to discover patterns in nonlinear and chaotic systems, neural networks offer the ability to. performance of the banks. This paper looks at an empirical analysis of the entire universe of 39 listed banks (comprising 24 PSU Banks and 15 PrSB) and attempts to find correlation between NPA levels and stock market performance of listed banks III.
