Impact of Future Derivatives on Stock Market Volatility
Derivatives has been the talk of the financial world after it was accussed as the primary reason for such a deep financial crisis that affecetd the global economy in 2007. Thus, the modelling of asset returns and judging the volatility of stock market and whether the derivatives have a substantial effect on stock market volatility, is still the key task for every finance professional as it provides much needed on risk patterns involved in investment process. The Finance Gurus propose that stock market normally exhibit high levels of price volatility and cause concerns to the investor regarding unpredicatble outcomes, however with launch of derivatives in the nineties in the major financial hubs, the volatility of stock market has become more complicated with derivatives offering new areas and scope of hedging and speculation. Thus, it is important to examine the impact of derivatives on stock market volatility. (O'Connor)
At time of introduction of derivatives, it was said that it is being launched with the twin objective of increasing liquidity and mitigation of risk. However, the finance world is still figuring it out whether these objectives have been materialized or not as it carries both theoretical and practical importance with it. Thus, with the help of stress testing models like GARCH and other models we will be looking on the impact of future derivatives on stock market volatility.
Introduction:
The completeness feature of the market has generated the need for introducing innovative financial instruments with the objective of creating efficient portfolios along with security from price fluctuations. Thus, with futures and other derivative instruments offeri...

...micians, this method was developed by Boolersleva nd Taylor. GARCH modles have the ability to allow conditional variance to depend on its previosu lags. Thus, this method allows interpretation of the current variance fiited in the model as weighted function of previous period volatility and fitted variance of previous period. Condluded to beter than ARCH Model, although GARCH(1,1) can be further generalized with GARCH(p,q) model but since GARCH(1,1) captues sufficient volatility most of the practioners avoid GARCH(p,q) model.
GARCH(1,1) is expressed as:

Equity markets have become much more volatile. The Chicago Board Options Exchange (CBOE) Volatility Index (VIX) is a “key measure of market expectations of near-term volatility conveyed by S&P 500 stock index option prices. Since its introduction in 1993, VIX has been considered by many to be the world's premier barometer of investor sentiment and market volatility.” When the last M&A Outlook was written, the VIX was at 11.57. At the start of November 2007, the VIX had increased to 23.21.
Stock is one of the greatest tools ever invented for building wealth. But parallel to the possibility of gaining, there is a great possibility of loosing. The only thing that can protect one from loosing is knowledge about movements in stock prices. Unfortunately, there is no clean equation that can tell us exactly how a stock price will behave, but we can try to find some factors that cause stock prices go up or down.

A generation ago, it was generally believed that security markets were efficient in adjusting information about individual stocks and stock market as a whole (Malkiel, (2003)). However, we cannot deny the efficient market hypothesis has several paradoxes.
The expanding global market has created both staggering wealth for some and the promise of it for others. Business is more competitive than ever before, and every business, financial or product-based, regardless of size or international presence is obligated to operate as efficiently as possible. A major factor in that efficient operation is to take advantage of every opportunity to maximize profits. Many multinational organizations have used derivatives for years in financial risk management activities. These same actions that can protect multinational organizations against interest rate futures and currency fluctuations can be used to create profits for those same organizations.
In this paper I will discuss the growth and development of the Capital Asset pricing Model (CAPM).I will also identify and analyze the different applications to the CAPM. I will try and illustrate how the model can be used to form expected return and valuation measures. These illustrations will be informed by examples from stock options and restricted stock. Finally I will conduct a comparative analysis of the potential outcomes associated and comparative benefits and risks for using the CAPM versus the Arbitrage pricing theory (APT).
Stock market prediction is the method of predicting the price of a company’s stock. It is believed that stock price is lead by random walk hypothesis. Random walk hypothesis states that stock market price matures randomly and hence can’t be predicted. Pesaran (2003) states that it is often argued that if stock markets are efficient then it should not be possible to predict stock returns. In fact, it is easily seen that stock market returns will be non-predictable only if market efficiency is combined with risk neutrality. On the other hand it is also been concluded that using variance ratio tests long horizon stock market returns can be predicted....

After the financial crisis of the late 1990s, the demands for risk management tools have increased. The investors have been effectively utilizing such products as KOSPI 200 futures and options, 3-Year KTB futures and USD futures to meet their hedging needs.
The importance of the topic is including a reduction in the risk and losses. Hedging effectiveness improved portfolio risk/return. Hedging is one of the main functions provided by future market and also the reason for existence of future markets. The main purpose and benefit of hedging on the futures markets is to minimize possible revenue losses associated with the adverse cash price changes. The risk of price variability of an asset can be managed by mechanism of
A derivative is a security with a price that is dependent upon or derived from one or more underlying assets. The derivative itself is a contract between two or more parties based upon the asset or assets. Its value is determined by fluctuations in the underlying asset. The most common underlying assets include stocks, bonds, commodities, currencies, interest rates and market indexes. Derivative products like futures and options are important instruments of price discovery, portfolio diversification and risk hedging. The current scenario shows that the volatility spillover between spot
Bond and stock both belong to negotiable securities, although both have their own characteristics. Bond and stock as a member of the securities system, which is a fictitious capital, they are no actual value, but they are the representatives of the real capital. Holding bond and stock are likely to obtain revenues. Also, bond and stock are the means of financing, compared with indirect financing such as bank loans, issuance of bonds and stock financing are large, long-term, low-cost, and not subject to the conditions of the lending bank. But, the mutual effect of yield from a single bond and stock, their yields are often differences and sometimes there such a big gap. However, if the market is effective, the average interest rate of the bond and the average return rate of the stock will generally remain relatively stable relationship, the difference reflects the degree of risk difference between the two. Looking with dynamic, the rate of return of the stock and prices and bond’s interest rates and prices are affect each other, often in the securities market with the movement in the same direction, for example, when the stock goes up then the bond will be going up too, but not exactly same range. These are the relationship between stock and
Using the Modern Portfolio Theory, overtime risk assets will provide a higher expected rate of return, as compensation to the investors for accepting a high risk. The high risk will eventually lower collecting asset classes to the portfolio, thus reducing the volatile risk, and increasing the expected rates of return. Furthermore the purpose of this theory is to develop the most optimal investments portfolio which would yield the highest rate of return while ascertaining the risk for the individual or corporate investor.
