Fоr this exаm, yоu will be wоrking with quаrterly stock return dаta from January 2006 through December 2024. During this period, the stock market experienced several significant events, including the 2008 financial crisis, the recovery that followed, and the disruptions caused by the COVID-19 pandemic and subsequent economic responses. These events, among others, led to substantial fluctuations in stock returns, making the data particularly intriguing for time series analysis. By examining less granular data—specifically quarterly stock returns—we can uncover insights related to the market's behavior over time, accounting for trends, seasonality, and potential volatility. It is important to note that you are required to write your answers as a report for this exam, as this format will allow you to demonstrate your ability to communicate your findings effectively. The data for this analysis is divided into two sets: train_data: This dataset will be used for all questions.validation_data: This dataset will be used specifically for Section 3, where you will compare your model's predictions to the actual data.In Section 1c, it may be useful to use the entire dataset (train_data + validation_data) to streamline your analysis and save time. Lastly, in Section 3d, you’ll apply your best model to the entire dataset to generate predictions, which will be compared against others. Exam Structure: - Section 1: Decompose the time series to explore its trend, seasonality, and stationarity.- Section 2: Apply Prophet to the data and forecast.- Section 3: Apply ARIMA modeling techniques to the residuals of one model from Section 1 and directly to the data.- Section 4: Forecast future stock returns using the best model from the previous sections. In Section 4, you will select your “champion” model and submit your forecast predictions in a separate module, which will be evaluated against others. This is an optional task. Note: the exam ends in 4c. Please note: You are required to submit your final analysis as a PDF file. Other formats will have a penalty. This exam will give you a practical understanding of working with financial time series, as well as a chance to demonstrate your ability to apply statistical modeling techniques for forecasting stock returns.
