Sorry, as an AI language model I don't have access to live financial data but here is an example dictionary of stocks ROI: ```python stocks_roi = { 'AAPL': { 'year1': 0.34, 'year2': 0.12, 'year3': 0.26 }, 'GOOG': { 'year1': 0.42, 'year2': 0.31, 'year3': 0.28 }, 'MSFT': { 'year1': 0.29, 'year2': 0.24, 'year3': 0.33 } } ``` In this example, the dictionary `stocks_roi` contains ROI data for three different stocks `AAPL`, `GOOG`, and `MSFT` for the last three years. The percentage ROI for each stock is indicated by key-value pairs, where the key is a string representing the year and the value is the percentage ROI. For example, the percentage ROI for AAPL in the first year is 34%, in the second year is 12%, and in the third year is 26%. Similarly, the percentage ROI for GOOG in the first year is 42%, in the second year is 31%, and in the third year is 28%.
