During the past two decades, the market has shown a lot of volatility, which is why investors look to global stock indexes for a way to gauge how markets are doing. For instance, if you are a long-term investor, you may want to look at the monthly returns for the Nasdaq Composite or the S&P 500 index. These indexes are more volatile than the S&P 100, and they offer a more comprehensive look at what is going on in the economy.

Table 3: Pearson correlations

Using data from 67 stock market indices in the last five years, Liu and Tse analyzed the correlation structure of the world stock markets. They characterized stock market network edges by using the Pearson correlation coefficient.

The paper uses a complex network approach to analyze the connections among the stock markets. They found that the French stock market is the most important node of the MST-Pearson. They also found that the MST-Pearson forms two large clusters: the European cluster in two subgroups and the American cluster with the USA at its center.

The Pearson correlation coefficient is a measure of the strength of a linear relationship. For instance, a positive correlation means that the value of one variable increases. The opposite is true for a negative correlation.

The correlation is measured as the product of the covariance of two random variables. This covariance is defined as the product of the standard deviations of the two random variables. Its value falls within a standardized range of -1 to +1.

COVID vaccine arrival

Vaccine news has had a modest impact on global financial markets. A setback in the pandemic could have significant implications for global financial markets.

Positive news about a potential vaccine for a pandemic has boosted risky assets. However, the positive news has not offset the easing impulses from equity markets.

Vaccine-related news was particularly significant in the euro area. The euro area equity markets benefited more from the positive news than US counterparts. The euro area has also experienced more of the risk-free yield increase, but financial conditions have tended to ease overall.

There are a number of factors that have influenced the impact of vaccine news on global financial markets. These factors include macro-economic factors, past macro-news, and market stress.

Positive news about a potential vaccine is most significant when it relates to longer-term risk-free yields. The announcement has also had an impact on the likelihood of vaccine delivery in the near term.

COVID vaccine effect on stock returns

Various studies have been conducted to examine the effects of the COVID vaccine on global stock indexes. The focus of these studies is to understand how different countries react to vaccine-related news and how these events impact different segments of the market.

Some of the studies have analyzed the short-term effects of the COVID-19 pandemic on the stock market. Others have focused on the long-term effect of the pandemic. Some of the studies also evaluated the effect of vaccines on pharmaceutical firms. These factors have been evaluated using python libraries.

Some studies have examined the effects of the COVID vaccine on the US stock market. Others have examined the effects of the pandemic on emerging stock markets.

Some studies have also examined the impact of the Ebola outbreak on the US securities market. These studies have found that the pandemic had a negative impact on the stock market. They also found that the stock performance of smaller companies was much worse than the stock performance of larger companies. They also found that stocks of companies with operations in West Africa were adversely affected.

COVID vaccine effect on Shariah compliant stocks

Earlier this week, stocks of Moderna Inc rose by a whopping 4x value. This was after the company announced progress on its COVID vaccine. Historically, this stock has been Shariah compliant. The company’s stocks have been classified as Shariah non-compliant during the growth phase of its business, but they are expected to be classified as Shariah compliant when they are mature.

The company is a research-stage biotechnology company that is Shariah compliant. The company derives all of its income from Shariah permissible business activities. The company’s stocks were found to be Shariah compliant after a screening process, which includes a financial ratio.

The Dividend Purification ratio is one of the financial ratios that is used in Shariah screening. The Dividend Purification ratio accounts for interest income that is not part of the operating business. Typically, companies that pass the financial ratios are involved in interest-based banking. If the income from interest income exceeds 5% of total income, the company may be classified as Shariah non-compliant.
