If history is any guide, there may be trouble ahead for shares of ZoomInfo Technologies. A so-called death cross has formed on its chart and, not surprisingly, this could be bearish for the stock. Many traders use moving average crossover systems to make their decisions. When a shorter-term average price crosses above a longer-term average price, it could mean the stock is trending higher. If the short-term average price crosses below the long-term average price, it means the trend is lower. The 50-day and the 200-day simple moving averages are commonly used. The death cross occurs when the 50-day moves below the 200-day. This could mean the long-term trend is changing. That just happened with ZoomInfo Technologies, which is trading around $52.80 at the time. Seasoned investors don't blindly trade Death Crosses. Instead, they use it as a signal to start looking for short positions based on other factors, like price levels and company fundamentals & events. For seasoned investors, this is just a sign that it might be time to start considering possible short positions.
