A support level is a price point on a stock chart that an asset has difficulty falling below over a specified period of time. It acts as a form of ‘floor’ preventing the price from falling further. Traders and investors consider support levels when planning their entry and exit points in the market.
Definition and Concept
Support levels are typically identified through peaks and troughs in a stock’s price history. A support level is considered strong if the asset price has tested it multiple times without breaking below it. Conversely, if a support level is tested repeatedly and finally breaks, it can signal a potential downward trend.
Identifying Support Levels
Visual Analysis
One common method for identifying support levels is to look for price areas where the asset repeatedly stops falling and bounces back. These areas can often be identified on a stock chart by placing horizontal lines at the price levels where the stock has shown a tendency to stop falling and reverse its direction.
Technical Indicators
Several technical indicators can help traders identify support levels:
- Moving Averages: These can act as dynamic support levels.
- Fibonacci Retracement: Levels derived from the Fibonacci ratio can reveal potential support levels.
- Volume-by-Price Analysis: High trading volumes at specific price levels can suggest strong support.
Trading Strategies Using Support Levels
Buying at Support
Traders often enter long positions when the price of an asset approaches a known support level. The rationale is that the price is likely to bounce back up from the support, leading to a profitable trade.
Setting Stop-Loss Orders
Placing stop-loss orders just below support levels is a common risk management strategy. If the support level fails, the trader’s loss is minimized by the execution of the stop-loss order.
Combining with Resistance Levels
Support levels are often considered in conjunction with resistance levels—price points where the stock has difficulty rising above. This combination is used to define a trading range and develop strategies such as trading the range or preparing for a breakout.
Historical Context and Relevance
Understanding the historical context of support levels can provide insight into market psychology and sentiment. Historically, notable support levels may correspond with significant events or trading anomalies, impacting future market behavior.
