The present study proposes to investigate the influence of the covid-19, on the adjusted closing price of the digital currency based on energy consumption during the process of mining. The study employed the secondary data analysis of top ten market capitalization of cryptocurrencies with the combination of high energy consume mechanism (proof of work) and low energy consume mechanism (proof of stake). Statistical tools like Descriptive analysis,Augmented Dickey-Fuller (ADF) test, ARCH, and GARCH models were used in the study. The present study finds that the prices of cryptocurrencies were highly volatile. This study could assist investors towards better understanding of the dynamics of the cryptocurrency market based on energy consumption which helps them to make more effective decisions, on investing cryptocurrencies with a scientific approach.

The aim of the study was to investigate the presence of volatility among the Energy Indices of Asia Pacific Stock Markets. To test the volatility among the daily returns of Energy Indices of Asia Pacific Stock Markets, the study selected five sample Asian Pacific stock markets’ Energy Indices on the basis of availability of data. The findings of descriptive statistics and the ADF Test revealed, that the daily returns of the sample energy indices of Asian Pacific stock markets were not normally distributed and achieved stationarity at level difference, over the research period. Hence the data may be used for additional analysis. The data were then analysed, by using the GARCH (1,1) model to assess the considerable volatility of daily returns of sample energy indices and the study, which revealed that during the study period, all of the sample energy indices were volatile.

The purpose of this research was to examine the dynamics of volatility spillover between energy and environmental, social, and sustainable indices. COVID19 prompted the research to select April 2019 to March 2022 as a sample period, and the respective data (Daily Prices) of the Nifty Energy and Nifty ESG indices were obtained from the National Stock Exchange of India Limited. The outcomes of the study confirmed that the daily returns of Nifty Energy and Nifty 100 ESG indices were not normally distributed and reached stationarity at level difference. Further, the study employed GARCH Models such as ARCH, GARCH (1,1), and GARCH-M to determine conditional volatility, and it validated the ARCH influence on the daily returns of the Nifty Energy and Nifty 100 ESG, during the study period

The research intends to assess the efficiency of NSE Energy Index-listed firms throughout the COVID-19 before and post pandemic phases, which run from 2019 to 2021. The primary goal of this article was to examine the price movement of corporations in the petroleum, gas, and electricity sectors by employing statistical methods such as descriptive statistics, ADF, and the GARCH (1,1) model, during the period of study. When comparing the post-COVID-19 pandemic era to the pre-COVID-19 pandemic period, certain firms experienced excessive volatility. The energy market's investor sentiment was significantly higher on the tail events, suggesting that anxious investors raced to put options and paid an exorbitant premium to shield them against unprecedented danger in the energy market.

Risk, diversification, features of investment avenues, and tax benefit are the factors considered by the investors in their decision making. The convenience of investing in small proportions and tax benefits attracts the investors towards mutual fund investments. The studies prove that market timing ability of fund managers drives the mutual fund scheme performance. This assessment of the above factors would help to the investors in their choice of mutual funds. 36 Indian Mutual Funds Schemes were assessed using the Sharpe, Treynor, Jensen’s measure from January to June 2019. L&T Liquid Fund –Direct (Growth), L&T Low Duration Fund-Growth and Edelweiss Large Cap Fund - Direct (Growth) performed well.

The information about changes in economic policies in a country may influence its stock market. The demonetisation has its impact on various segments of the economy. Thus the study aims to analyse the price movement of Indian sectoral indices around the demonetisation announcements. The daily price returns were tested using GARCH (1, 1) Model and it found that low volatility was found in the post announcement period compared to the pre-announcement period. Thus the present study confirmed that Indian sectoral indices were influenced by the demonetization announcement. Therefore, investors should be aware of economic events while investing in the stock market.

Changes in an index are a regular phenomenon and they take place due to the inclusion and exclusion of stocks from the index. The inclusion or exclusion of stocks creates great impact on the value of the firm. However, these changes are simply a short-lived event with no permanent valuation effect. The present research study analyzed the impact of the inclusion into and exclusion of certain stocks from National Stock Exchange (NSE) S&P CNX Nifty index with Indian perspective. The study provides evidence on whether the announcements of Nifty index maintenance committee have any information content. This will also demonstrate the efficiency of Indian stock market with particular reference to NSE. The study revealed that on an average, no permanent effects were observed on stock prices. It is also found from the study that the NSE reacted unfavourably to the inclusion and exclusion of stocks and it is impossible to earn any excess returns where the particular stocks are included or excluded from the index.

An efficient and integrated financial market is an important infrastructure that facilitates savings, investments and consequent economic growth. The financial markets include money market and capital market. Capital market is the market for trading long-term securities whereas; money market is for short-term securities. It is a universally accepted fact that the financial system and the capital market in particular act as the barometer of the health of an economy. Free and efficient capital markets ensure that the resources are allocated wisely and faster. The event study is an important research tool in economics and finance. The goal of an event study is to measure the effects of an economic event on the value of firms. Event study methods exploit the fact that given rationality in the marketplace, the effects of an event will be reflected immediately in security prices. Thus, the impact can be measured by examining security prices surrounding the event. There are various types of events like Mergers&Acquisitions, Quarterly Earnings, Dividend Issue, Bonus Issue, Stock Split, Buyback of Share, etc. that has a reaction over the prices of securities in the capital market. Bonus shares are free shares of stock given to current shareholders, based upon the number of shares that a shareholder owns. While this stock action increases the number of shares owned, it does not increase the total value. This is due to the fact that since the total number of shares increases, the ratio of number of shares held to the number of shares outstanding remains constant.
