Volatility is a statistical tool that is used to measure the degree of dispersion of the of the return from the mean position. Volatility can be measured by various methods. These include:
Volatility helps in understanding the risk associated with the magnitude of changes in a security's value.
In statistics, volatility can be calculated using the below process:
Example explained using excel:
Data smoothing is a process of manipulating data to eliminate or reduce short-term volatility, pulling out real patterns or trends from data results. Smoothed data assists in identification of changes in an economy by predicting different patterns and trends.
Key currencies are very liquid and widely acceptable. These currencies have a strong government, and volatility in the foreign exchange rate is stable, which makes these currencies suitable for transactions.
Narrow market is the market with a smaller number of buyers and sellers, and is further characterised by high price volatility, low liquidity of assets, and only few transactions occurring in the market. Due to limited number of transactions taking place, it is a common scenario in a narrow market where there are very less investors who sell and buy only particular shares.
What is capital? Capital refers to the financial assets held by a firm and/or funds outsourced from other forms of financing. Capital can have multiple meanings; however, this is the definition used in finance. In a more general sense, capital is understood as anything that generates more value. Capital can be defined differently based on the usage of the term. In finance, capital refers to the equity, debt, investments and working capital held by firms. In economics, capital refers to human capital which is the capacity of individuals in an economy to contribute towards economic production. Natural resources may sometimes also be referred to as capital; however, this usage of the term is excluded from both economics and finance. Is money a form of capital? Money cannot be strictly defined as capital because money itself is an instrument to purchase goods and services which end up becoming the capital. For instance, the investments made in financial instruments by firms are a form of financial capital. Thus, any money held by a firm may not precisely be termed as capital; however, once it is invested in financing activities, it becomes a form of capital. What are the components of financial capital? Financial capital includes the following: Debt: The most common form of capital used in business is debt. Firms may take borrowings from banks or from family members to finance their operations in the beginning. In case of borrowings from the banks or any monetary institutions, firms must repay the principle with interest. Debt is an easy method of financing business activities; however, the interest associated with it might make it expensive for some. If the business fails, the borrower must repay the debt. The advantage of taking a loan is that the profits need not be shared. Equity Capital: The type of capital comes from investors who put their money in the initial stages of the company. This is done in exchange for a part of the profits that must be shared with the investors in the future. Businesses may initially fund their processes themselves; thus, they own 100% equity and would earn all the profits. However, angel investors or venture capitalists may sometimes invest too. In those cases, a proportion of the profits goes to these investors. This may be disadvantageous in some cases, where investors end up taking a large stake in the company in exchange for initial capital provided by them. Businesses that are at an early stage might benefit from the initial investment; however, their profits in future are decreased by a large percentage. Working capital: This includes the most liquid assets that a company possesses. These are the assets that can be easily converted to cash. Working capital is maintained to fulfil daily transactions and is calculated on a regular basis. It can be obtained by subtracting current liabilities from current assets, or by adding accounts receivables and inventory, and subtracting accounts payable from both. To summarise, working capital is derived as: How is financial capital different from economic capital? Financial and economic capital are both utilised in a business. However, financial capital is a much broader term. Economic capital, on the other hand, refers to the estimated amount of money required to bring a firm out of losses. It can be interpreted as the amount of money required to repay the outstanding liabilities. The concept of economic capital was introduced to manage risk. This is used to analyse the amount of funds that would be required to compensate any losses in the future. There are various models used to determine the capital needed to manage risks. Economic capital may sometimes also include human capital, or the tools used to produce goods. In economics, capital may also refer to one of the factors of production used in producing goods and services in an economy. Out of the two, financial capital is the most prime version utilised by firms and is commonly seen across businesses. Therefore, if used alone, the word capital most commonly refers to financial capital only. What is the cost of capital? There is a cost associated with acquiring capital. Since capital includes loans and borrowings to finance the business, the cost of capital depends upon the coupon, interest rates, and yield to maturity of the debt. The Capital Asset Pricing Model or CAPM is used to calculate the cost of equity. CAPM uses the volatility of the returns as a measure of calculating how much the investment should cost in a year. On the other hand, cost of debt is equal to the interest paid on loans. Cost of equity would always be higher than the cost of debt. This is so because the cost of equity is riskier and more vulnerable to fluctuations. Why is capital important for businesses? Capital allows businesses to expand and grow in wealth. It boosts productivity in the economy and provides valuable goods and services necessary to sustain. Businesses realise the importance of maintaining capital and they use various methods to analyse on how to maintain it.
