In this paper, we examined if the Black and Scholes model is a good descriptor of option pricing in the Indian context. We use data for Standard Poor CRISIL NSE Index 50 (S&P CNX Nifty index) options from 1st January, 2004 to 31st December, 2005. We operationalise the Black and Scholes model using two alternative measures of Historical volatility and Weighted implied volatility. Employing the historical volatility measure, we find that both call and put options are fairly priced in India subject to the trading asymmetry condition in the spot market. However, weighted implied volatility measure grossly underestimates option values resulting in large and positive pricing errors. Thus, option pricing in India seems to be conditionally efficient and historical volatility does a good job...
For futures contracts, option-pricing models provide a significant source of information on the market consensus regarding price movements until expiry. Given the quantity of price information available through option price data the results of viewing future price predictions included in basic option pricing models seem well worth the effort. The breakeven prices are those that will permit a trader who uses a delta-neutral trade, using the delta slope (hedge ratio) to determine how many call options to buy in hedging a short sale of one futures contract. It is easy to see the relationship of the upper and lower breakeven prices with volatility measures. Traders in the option market make predictions on future price movements as they estimate the chances of profits or losses on various co...

Intangible assets facilitate insurers' capacity to retain existing business and attract new clients. In this study we analyze how the incentives to protect intangible assets affect asset risk-taking behavior of property and liability insurers. The result supports the view that insurers' incentives to protect their intangible assets lead to an inverse relation between intangible assets and asset risk. Consistent with the view that highly levered firms may go for broke, asset risk of highly levered insurers is less elastic to intangible assets than that of lower-levered insurers. An additional notable finding of our article is that tangible factors like firm size and capitalization increase insurers' appetites for asset risk taking.

One option spread strategy that requires a trader to estimate relevant high and low strike prices between the trade date and expiration is the short option strangle. Future price ranges may be estimated based on charts of past price movements or by various forms of fundamental analysis. Another method is the LLP (log-log parabola) option-pricing model. This method is compatible with the Black-Scholes option-pricing model that is the basis for most valuations in the option market. The regression equation computed by the LLP model generates predicted call prices that closely match current market prices. Since the early 1970s, option markets have been priced by the Black-Scholes model or similar logarithm-based models. LLP call and put price calculations reflect market pricing and compute ...

Using the framework of econometric models, this paper investigates three research questions and finds positive answers. First, is the volatility of Small Cap 600 predictable? Second, does the volatility of Small Cap 600 exhibit the same empirical regularities reported in the literature about the behavior of other stock prices? Finally, can Small Cap 600 pass a test of market efficiency? These research results will benefit the following entities: (1) economic agents investing in Small Cap 600, (2) business professors interested in Small Cap 600 for teaching and research, (3) policy makers who are watching the stock market volatilities because the volatilities of the stock markets dampen investors' incentive to invest, among other consequences.
