The golden cross is a technical indicator that occurs when a stock's 50-day moving average crosses above its 200-day moving average. This is generally considered a bullish signal, suggesting that the stock's long-term trend may be changing. In the case of Toyota Motor, the formation of a golden cross could lead to an increase in the stock's price in the short term, as investors may interpret this as a positive sign and start considering long positions based on other factors such as price levels and company fundamentals.
