How do investors use a Fibonacci retracement?
The Fibonacci retracement is a tool that’s fairly easy to understand in theory but often difficult to execute in practice. The Fibonacci retracement levels don’t change (23.6, 38.2, and 61.8, with the last figure approximating the Golden Ratio).
Many investors who rely on technical analysis think the Fibonacci retracement makes perfect sense for setting price goals, entry points, or stop-loss orders. The idea is to watch where a price goes when it reaches one of the three primary retracement numbers and see if the price is going up or down. If it’s going up, it might be a good buy; if it’s going down, it might be time to get rid of it. The idea is to watch the trend, identify the retracement, then trade in the direction of the trend.
Like any other form of technical analysis, Fibonacci retracements are best used in combination with other information and over longer time periods to eliminate the risks of routine volatility skewing the analysis.
It may be hard to believe that random numbers developed almost a millennium ago by an Italian mathematician would have much relevance for a modern stock market. Critics argue that corrections in prices are likely by chance alone simply because of Fibonacci levels at 23.6%, 38.2%, 50%, and 68.1% -- a pretty broad swath of potential price changes. Advocates of the Fibonacci retracement strategy note that academic studies have supported the approach, including a 2022 Financial Innovation study of cryptocurrency and energy industry stock prices.
