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, as it suggests that the stock's short-term momentum is increasing relative to its long-term trend. In the case of Bio-Techne, the formation of a golden cross could indicate a potential uptrend for the stock, which may attract more investors and drive the stock price higher in the short term.
