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 is changing. In the case of Brookfield Infrastructure Partners, the golden cross could indicate a potential upward trend for the stock in the short term. However, it's important to note that seasoned investors don't blindly trade golden crosses and consider other factors like price levels and company fundamentals before making decisions.
