Ralph Acampora explains the logic behind technical analysis. He notes that a study of fundamentals will give you a good understanding of a company. You need to study the technicals to have an understanding of the stock price; "You have to look at the charts," he says.

There were conflicting fundamentals on stocks in 2019, and Acampora waited to see if a stock's price demonstrated resistance on the top side, or support on the bottom, before deciding on the direction. He says technical analysis is often reacting to what the chart shows, you want to let the price tell you the direction.
