In financial markets, volatility modeling has been a strategy widely used because it reflects uncertainties about changes in asset prices. Incorporating peculiarities of financial series, this study estimated the volatility for the intraday index of the Brazilian stock market (Ibovespa) using ARIMA-APARCH models in different time frequencies with the aid of the wavelet MODWT decomposition technique. This work proposes an analysis of the impacts of the frequency components on the behavior of the volatility of intraday returns using the series of details wavelet in different time horizons, in an atypical period in the global financial markets, generated by the COVID-19 pandemic. The empirical results suggest low unconditional volatility and strong signs of persistence in all analyzed frequencies. The asymmetry in volatility is evidenced in the higher frequencies, the leverage effect being present only in the series of details with variations of 15-120 min., which is corroborated with the results obtained with the reconstructed series. The evidenced behaviors have an impact on the elaboration of short-term investment strategies and risk management, since the positive and negative shocks, such as those given by the world pandemic of COVID-19, have different impacts on the volatility of returns in shorter periods. The information obtained can contribute to the analysis of future atypical events in the Brazilian stock market, supporting the decision-making of economic agents.

Indian Stock Market

FIIs are companies registered outside India. In the past four years there has been more than $41 trillion worth of FII funds invested in India. This has been one of the major reasons on the bull market witnessing unprecedented growth with the BSE Sensex rising 221% in absolute terms in this span. The present downfall of the market too is influenced as these FIIs are taking out some of their invested money. Though there is a lot of value in this market and fundamentally there is a lot of upside in it. For long-term value investors, there’s little because for worry but short term traders are adversely getting affected by the role of FIIs are playing at the present. Investors should not panic and should remain invested in sectors where underlying earnings growth has little to do with financial markets or global economy.

The article reveals the essence and features of the development of the stock market in Ukraine. It was established that the vigorous activity of countries in the world financial markets means that they also face a risk of global financial turmoil (the so-called “domino effect”). It is determined that the impact of global financial instability on the country depends on the openness of its economy that will lead to significant external “shocks”. The possibility of providing effective influence on domestic stock market activity with taking into account the changing world situation, development of perfect trading strategies for each participant is substantiated. The conducted analysis of the world market conditions of stock markets in recent years has made it possible to assess the real risks for new participants in the stock market and become the basis for the development of an appropriate effective trading strategy. The practical significance of the results is that they allow for a measurable approach to assessing the existing risk when choosing one or another trading strategy to move to the world stock market.

The COVID19 pandemic which came unprecedentedly has brought forward a lot of confusion and unrest in the world. There are a lot of changes with regard to the global landscape in multiple ways. SARS-CoV-2 is the primary virus, which is the root contributor to the COVID19 outbreak, which started in Wuhan, Hubei Province, China, in December 2019. It did not take much time to spread across the world. This pandemic has resulted in a universal health crisis, along with a major decline in the global economy. One of the major reasons for the fluctuation in the stock price is supply and demand. When the number of people who want to sell their stocks outnumbers those who want to purchase it, the stock price drops. Due to the result in the gap, the financial markets will suffer in the short duration, but in the long run, markets will correct themselves and would increase again. There is a sharp decline in the stock price because of the pandemic. The current scenario has resulted in a world health crisis which has contributed to global and economic crises. Almost all financial markets across the world have been affected by the recent health crisis, with stock and bond values falling gradually and severely. In the United States, the Dow Jones and S& P 500 indices have fallen by more than 20%. The Shanghai Stock Exchange and the New York Dow Jones Stock Exchange both indicate that they had a significant impact on China’s and the United States’ financial markets. The primary purpose of this paper is to determine the impact of COVID19 on stock markets. The rapid spread of the virus has left a major impact on the global financial markets. There is a link between the pandemic and the stock market, and this has been studied in this paper. Along with it, an attempt is taken to compare stock price returns in pre-COVID19 and post-COVID19 scenarios. The stock market in India faced uncertainty during the pandemic, according to the findings.

The Way

The aim of this study is to examine the phenomenon of framing as a cause of making wrong decisions while investing in Islamic stocks. Framing refers to the bias of people that describes the way they respond to a specific option as per its offer. After collecting primary data through interviews, including open-ended questions from the Pakistani stock market under the subjective or constructivist research paradigm, NVivo it is applied to get word cloud for appropriate analysis. The study finds that there are so many complexities and impurities that blindfold brokers and investors to differentiate between Shariah-compliant versus conventional stocks. This research can be further extended by differentiating between long-term and short-term investment horizons.

Significance Divided government provides scope for volatility at a perilous time for the pandemic-ravaged US economy, but markets are putting greater weight on the prospect of a vaccine accelerating the global recovery. Tech stocks have fallen as investors take their gains and opt for 'reflation trades' predicated on a recovery in sectors hit hard by the pandemic. Impacts Apple, Amazon, Alphabet, Microsoft and Facebook make up over 20% of the US stock market; firm fundamentals guard against a sharp sell-off. China’s renminbi has risen to the highest to the dollar since the US-China tariff battle ramped up in early 2018; more strength is likely. China’s export orders grew only marginally in October and import growth slowed, signposting that the world trade recovery could plateau.

Stock Market Valuations

The terrorist attack on New York on 11 September 2001 caused considerable disruption to the US economy, and especially to the US financial markets. The initial reaction of the financial markets was to increase the discount factor on future profits and reduce future profit projections, and hence stock market valuations fell markedly, as can be seen from charts 1 and 2. This fall has been largely reversed since the attack, but markets have in general continued their decline from their peaks a year or so ago. Falls have been particularly precipitate since July 2001, with the German and French stock market indices falling by 20 per cent over the last three months, whilst the Canadian markets have fallen even more. Stock market falls of the scale we have seen since July are almost bound to impact on the level of economic activity in the major economies. They are likely to reduce the rate of growth of the world economy over the medium term as well as change the structure of saving and investment.

Economic Foundations

AbstractThis paper argues that present-day imperialism is strongly related to the domination of a precise form of capital, namely highly concentrated interest- and dividend-bearing money-capital which operates in financial markets, breeds today's pervasive fetishism of money, but is totally dependent on surplus-value and production. Two mechanisms ensure the appropriation and/or production of surplus-product and its centralisation to the world system's financial hubs. In the 1980s, foreign debt prevailed. Foreign production and profit repatriation by TNCs now represent the main channel. Following the transfer abroad of part of its production by US TNCs, the issue for the US in their relations with the rest of the world is not the commercialisation of surplus through exports, but dependency on imports and, more crucially, on large inflows of money-capital to support the stock market, buy T-bonds and refinance mortgage. This new dependency helps to explain the 'paradox' that US imperialism is increasingly forced to try and offset this through extra-economic and even military coercion where it can.

Pertinent Question

This study is intended to reaffirm the existence and profitability of momentum investment strategies in 40 countries around the world during the period 1996–2018. The contradictory findings of previous research on the existence and profitability of momentum strategies have raised a pertinent question on the validity of efficient market hypothesis. We documented the momentum effect in 90% of our sample countries of which 52.5% exhibited positive momentum effect while 37.5% exhibited negative momentum effect. The findings were robust to two distinct sub-period analyses. The clear rejection of efficient market hypotheses is valuable to momentum traders and stock market regulators.
