Abstract: We examine the predictive power of a novel hybrid A3T-GCN architecture for forecasting closing stock prices of FTSE100 constituents. The dataset comprises 79 companies and 375,329 daily observations from 2007 to 2024, with node features including technical indicators (RSI, MACD), normalized and log returns, and annualized log returns over multiple windows (ALR1W, ALR2W, ALR1M, ALR2M). Graphs are constructed based on sector classifications and correlations of returns or financial ratios. Our results show that the A3T-GCN model using annualized log-returns and shorter sequence lengths improves prediction accuracy while reducing computational requirements. Additionally, longer historical sequences yield only modest improvements, highlighting their importance for longer-term forecasts.
