The paper presents the development of time series forecasting algorithms based on the Integrated Autoregressive Moving Average Model (ARIMA) and the Fourier Expansion model. These models were applied to non-stationary time series of stock quotes after bringing these series to a stationary form. In the paper, ARIMA and Fourier Expansion model were constructed, using Python development environment. The developed algorithms were tested on Russian and American stock indices using the Mean Absolute Percentage Error metric.

Many investors use market indices to manage their portfolios and keep track of the financial markets. Forecasting financial trends in a complex market is a critical factor for investors. Given how challenging and unpredictable future predictions can be, forecasting market indices cannot rely solely on regular patterns based on technical analysis. Therefore, this paper proposes a way to forecast future market indices of Financial Times Stock Exchange (FTSE) Bursa Malaysia Kuala Lumpur Stock Exchange Composite Index (KLCI) and MSCI All Country World Index (ACWI) by using geometric Brownian motio

In this study, we investigate the dynamic linkages between US and Indian equity markets by examining the daily Total Return Index values of NIFTY 50 and NASDAQ Composite over a decade ending October 2024. While the indices are not found to be cointegrated, suggesting potential long-term diversification benefits, they exhibit significant short-term correlations. Through various statistical analyses including regression, correlation, and variance tests, we find strong positive associations between the markets, with NASDAQ Composite movements explaining approximately 89% of variations in NIFTY 50

The ARIMA model differs from the ARMA model only in that forecasting is performed not on absolute values of series levels, but on differences of order d, which makes it possible to apply to non-stationary time series. Financial time series are traditionally considered non-stationary. However, the Hurst exponent less than or equal to 0.5 indicates a random or anti-persistent nature of time series.
