The risk in holding securities is generally associated with the possibility that realised returns will The stock's beta is computed with respect to the S&P 500 index when using daily data, there was no significant relation between stock returns and risk factors. “if a stock has a beta of 1.5 and the market rises by 1%, the stock would be This method of estimation makes the important assumption that the independent. Shorter periods can be affected more easily by significant firm-specific event that Noise is created by stocks not trading and biases all betas towards one. Portfolio beta describes relative volatilityof an individual securities portfolio, taken as a whole, as measured by the individual stock betas of the securities making Each beta is then multiplied by the percentage of your total portfolio that stock economic significance of these pricing differences is the “bid-ask spread” for

INTRODUCTION. The volatility or beta coeffi cient is an important unconditional distribution other than vola- tility (mean, skewness, and kurtosis), cor- relation with other stocks, the market or beta risk and its relative importance, Capital Asset Pricing Model (CAPM) is an extension of the Markowitz's Modern Portfolio Theory. This model was developed by the independent works of William

### 30 Aug 2017 stocks are significant and robust. The zero-cost portfolio that longs low-beta stocks and shorts high-beta stocks delivers monthly four-factor

First off before we even get into what is Beta more important question is why Stocks that have a higher volatility will have a higher beta so they may have a index and the stock, and how to run a regression to determine the beta regression coefficient is 0.7560 and has a t-statistic of 4.31 and is significant at the Beta. Risk is an important consideration in holding any portfolio. The risk in holding securities is generally associated with the possibility that realised returns will The stock's beta is computed with respect to the S&P 500 index when using daily data, there was no significant relation between stock returns and risk factors. “if a stock has a beta of 1.5 and the market rises by 1%, the stock would be This method of estimation makes the important assumption that the independent.

### A positive beta does not mean that a stock is going up in price. In fact, a stock that has a positive beta while the market is falling is more than likely falling at a higher percentage rate than the market. Likewise, a negative beta does not mean that a stock is going down in price.

In finance, the beta of an investment is a measure of the risk arising from exposure to general Beta can also be negative, meaning the stock's returns tend to move in the opposite direction of the market's returns. A stock with a beta of −3

## Alpha is the excess return on an investment relative to the return on a benchmark index. Beta is the measure of relative volatility. Alpha and beta are both risk ratios that calculate, compare

Beta can also be negative, meaning the stock's returns tend to move in the opposite direction of the market's returns. A stock with a beta of −3 would see its return decline 9% (on average) when the market's return goes up 3%, and would see its return climb 9% (on average) if the market's return falls by 3%. Definition: Stock beta, represented by the beta coefficient, is an investment metric that assesses the risk and associated volatility of a certain investment in relation to the market.In laymen’s terms, it’s an estimate of the stock’s risk or volatility in comparison to what the market reflects as the average risk. The beta (β) of an investment security (i.e. a stock) is a measurement of its volatility of returns relative to the entire market. It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPM). A company with a higher beta has greater risk and also greater expected returns. The beta is the number that tells the investor how that stock acts compared to all other stocks, or at least in comparison to the stocks that comprise a relevant index. Beta is a measure of a stock’s systematic, or market, risk, and offers investors a good indication of an issue’s volatility relative to the overall stock market. The market beta is set at 1.00, and a stock’s beta is calculated by Value Line, based on past stock-price volatility. If an equity has a beta of 1.00, it will probably move in
