Heteroskedasticity simply means that the variance of the sample investment performance data is not constant over time. As a result, standard deviation tends to fluctuate based on the length of the time period used to make the calculation, or the period of time selected to make the calculation. Once expected returns of a portfolio reach a certain level, an investor must take on a large amount of volatility for a small increase in return. Obviously, portfolios with a risk/return relationship plotted far below the curve are not optimal since the investor is taking on a large amount of instability for a small return.
Or else the trader can construct a bear put spread by buying the $90 put at $11.40 and selling or writing the $80 put at $6.75 (note that the bid-ask for the June $80 put is $6.75 / $7.15), for a net cost of $4.65. When the average daily range moves up to the fourth quartile (1.9 to 5%), there is a probability of a -0.8% loss for the month and a -5.1% loss for the year. However, investors should keep in mind that the high volatility of an asset could end up being either a blessing or a curse. While a highly volatile asset might suffer sharp downside, it might also experience substantial gains. Risk can take many different forms, but generally, assets that have greater volatility are perceived as being riskier because they have sharper price fluctuations. HV and IV are both expressed in the form of percentages, and as standard deviations (+/-).
Defining Volatility in Simple Terms
This forward-looking figure allows a trader to calculate how volatile the market will be going forward; for instance, the implied move and range for a currency pair with a significant degree of confidence. There are other similar indices in bond and currency markets implied by option pricing, which current us inflation rates are also very useful in measuring volatility. The pain is only relieved by pressing the sell button and there is often an inability to think rationally. This stage is the classic ‘be fearful when others are greedy, and greedy when others are fearful’ point, a well-known phrase uttered by legendary investor Warren Buffet. The strong hands are accumulating at this point, while the weak hands are still in liquidation mode. This loss of confidence sees plans and strategies changed or even forgotten as fear sets in, before the dreaded sense of despair turns into capitulation.
- The index is measured on a scale of zero to 100 – extreme fear to extreme greed – with a reading of 50 deemed as neutral.
- A higher standard deviation denotes greater volatility, indicating that the asset’s price can potentially spread out over a larger range of values.
- VIX does that by looking at put and call option prices within the S&P 500, a benchmark index often used to represent the market at large.
A fund with a beta very close to one means the fund’s performance closely matches the index or benchmark. A beta greater than one indicates greater volatility than the overall market, and a beta less than one indicates less volatility than the benchmark. The VIX—also known as the “fear index”—is the most well-known measure of stock market volatility.
It is often derived from the pricing of options and reflects market expectations of future volatility. For example, surpassing earnings expectations can lead to a positive surge in the company’s stock, while a merger announcement might lead to speculative trading, causing price fluctuations.

Investors must understand the factors affecting volatility, including economic indicators, market sentiment, political events, and company-specific factors. ATR measures the average of true price ranges over a specified period, giving traders an understanding of the degree of price volatility. Standard deviation is a statistical measure that provides an insight into the average variance from an investment’s mean return. In the realm of finance, it’s commonly used to gauge an investment’s volatility.

These moments skew average volatility higher than it actually would be most days. Some traders and investors engage in buying and selling based on short-term expectations rather than underlying fundamentals. This speculative activity can magnify price movements, especially in assets that are subject to rumours or are in the media spotlight.
They are the real foundations of price action when volatility increases and can occur on any time frame. There are many factors which cause volatility in markets, such as surprise central bank announcements, company news and unexpected earnings results. However, what links all of these together is that reactions are caused by psychological forces which every trader undergoes during the course of their trading day. Using a simplification of the above formula it is possible to estimate annualized volatility based solely on approximate observations. Suppose you notice that a market price index, which has a current value near 10,000, has moved about 100 points a day, on average, for many days.
In terms of performance below or above a threshold, it can also be determined that the S&P 500 Index experienced a loss greater than or equal to 1.1%, 16% of the time, and performance above 24.8%, 7.7% of the time.
