Balancing the relationship between investment risk and return to formulate trading strategies has become an urgent problem in the capital market. In the study, by analyzing the historical price data of gold and bitcoin from 2016 to 2021, the time series method combined with a simple moving average method was introduced to develop price prediction models of gold and bitcoin in the next trading day, accurate predictions of future price for both financial products were completed.
