Time series analysis, which stands out as one of the most important analysis methods used to determine future price movements, is used by bringing together data containing price movements that occur within a certain time pattern. Get ready to discover the secrets of technical analysis through this guide we have prepared for you, which reveals the definition of time series analysis, its advantages and disadvantages, how it can be used, which components it is divided into and what kind of contributions the data obtained through graphs make!
What Is Time Series Analysis?
When technical analysis in financial markets is considered, time series analysis, also known as trend analysis, comes to the fore. Time series analysis is a set of data containing interrelated events and transactions that occur within a certain period. For example, credit card statements are presented to users at equal intervals and in chronological order. The fact that the information on the statement is considered as data and that the data is sorted by time reveals the correlation between interrelated variables. In addition, other time-correlated variables such as sales data of an institution or the number of people reaching a call center on a day and hour basis can also be included in time series analysis.
When it comes to financial markets, time series analysis is the examination of the price movements of the asset of interest (stocks, commodities, FOREX, cryptocurrencies, etc.) together with periodic developments such as past price movements, earnings, gross domestic product (GDP) that are expected to affect the price. In this context, investors can obtain detailed information on whether a company’s performance is performing well before measures such as earnings per share (EPS), for example. Time series analysis is very important as it enables investors to make predictions based on price movements that have occurred as a result of past events.
How Does Time Series Analysis Work?
Trends, seasonal changes, cyclical patterns, and irregular movements, which are the main categories of time series analysis, play an important role in understanding market movements and predicting future price movements. Thanks to the AutoRegressive Integrated Moving Average (ARIMA) and other machine learning algorithms, investors can conduct analyses of a large amount of data more easily and shed light on the future. However, in this context, it is important to always use other technical indicators to support the data obtained, as incomplete or incorrect data from the past may lead to incorrect time series analysis.
What Are The Advantages Of Time Series Analysis?
The advantages of time series analysis for investors and their investment decisions can be listed as follows:
- Through time series analysis, investors gain insight into what kind of factors may affect variables and in which direction.
- Through time series analysis, especially for certain periodic periods such as seasonal changes, investors can perform their risk management accurately.
- Time series analysis is a tool to be used by investors in all financial markets, taking into account that all financial assets have historical price movements.
- Thanks to time series analysis, investors can make a detailed and comprehensive interpretation of the changes that may occur in the price and understand the reasons for them.
What Are The Disadvantages Of Time Series Analysis?
- Data points must be periodically linear. In this context, although investors may think that they are performing the correct time series analysis, the non-linearity of the data points will be a disadvantageous situation.
- Time series analysis may not be consistent with actual price movements in markets with significant volatility or in regions where geopolitical events such as economic crises occur.
How To Use Time Series Analysis?
To perform time series analysis correctly, investors need to analyze the data using the right methods. The process within the analysis can be listed as the collection of time data series, identification of patterns, modeling, and finally forecasting. Each stage of time series analysis should be carefully followed to ensure that the data are complete and accurate. Otherwise, the data obtained as a result of the analysis may be incorrect. To ensure the accuracy of the data in time series analysis, it is of great importance to always use other data analysis methods such as technical indicators.
What Are The Components Of Time Series Analysis?
Many components distinguish time series analysis, especially in terms of time, and these can be briefly categorized into four categories: trends, seasonal variations, cyclical components, and random movements.
Trend:
In financial markets, a trend is when prices move in the same direction for a long period. Accurate analysis of trends helps investors to make more accurate predictions about the upward or downward trend of prices.
Seasonal Changes:
Seasonality is used for situations where different periods of the year directly affect the data. To examine detected data in the category of seasonal changes in time series analysis, it must have realized the same price movements in similar periods in the past. Examples of seasonal variations include the sale of more airline tickets in response to the increased demand for vacations in the summer months, or ice cream sales that increase more when the weather is warmer than in the rest of the year. In the context of financial markets, the price changes of natural gas, as a commodity, can be taken into consideration during periods when the temperature increases.
Cyclical Components:
Cyclical components are situations that occur as a result of a specific event and affect the direction of the trend in financial markets in the long term. Cycles such as prosperity and recession can affect markets and industries in the long term. Although similar to seasonal variations, it should be recognized that cyclical variations are differentiated by occurring irregularly rather than at periodic intervals.
Random Movements:
The random component, also referred to as “noise”, is a series of events that occur within a smoothly analyzed time series analysis that usually affects short periods and does not change the integrity or direction of the trend, and cannot be categorized into any category. When these unpredictable events, such as natural disasters or political instability, affect short-term financial markets, they are described as “random movements”.
How Are Graphs And Charts Used In Time Series Analysis?
The impact of charts and graphs used in time series analysis is very important in understanding the direction and movements of the market.
By analyzing charts, investors gain insight into the price movements of financial assets, which helps to identify short-term movements and long-term trends, making time series analysis easier to perform. On the other hand, some other technical indicators applied to the chart also support traders in collecting data to perform time series analysis. For example, with moving averages, traders can obtain more accurate data to support how accurate their interpretations of the direction of the trend are.
On the other hand, charts can be broken down into seasonal data. A marker placed on the chart at the beginning of each season can shed light on the movements of the financial asset during the relevant season. In this way, the investor can categorize price movements into categories such as seasonal changes in time series analysis.
Another of the many contributions of charts to time series analysis is the historical perspective. Since the data on the charts goes back to ancient times, there is a wealth of data available for investors to collect and use in their analysis.
How Should The Time Series Be Used In Trading?
The following examples can be given for the use of time series analysis under the trading category:
- Collection of Time Data Series: At this stage of time series analysis, data on many different market movements such as price movements and trading volumes that are inherent part of the financial markets during the historical period are gathered together.
- Identifying Patterns: The next step for the collected data is to determine the direction of price movements and which category they belong to within the components of time series analysis. In this sense, it is determined whether the trend is bullish or bearish at the time of the variable of interest and whether seasonal changes or cyclical components, etc. prevail.
- Modeling:The third stage is described as modeling, where the events that cause the observed patterns are identified. In the modeling stage, the data and patterns are analyzed with models such as Autoregressive integrated moving averages (ARIMA), which are generally used in statistics and econometrics, and a forecast is made for the future.
- Forecasting:Thanks to the modeling performed in the previous stage, investors infer the possible future effects of the results obtained in the relevant time series analysis.
