Understanding Bollinger Bands
Developed by John Bollinger in the 1980s, Bollinger Bands are more than just an average market wrapper – they are dynamic tools that reflect the market’s volatility and provide a tactile feel for the rubber-band-like elasticity of stock prices. These bands serve up a statistical smorgasbord, empowering traders to sink their teeth into juicy market opportunities or steer clear of potential investment lemons.
How Bollinger Bands Work
The centerpiece of the Bollinger Bands is the 20-day simple moving average (SMA), which acts like the belt holding up the trousers of the trading strategy. Flanking this SMA are two other lines (the upper and lower bands) that puff up and deflate like the cheeks of a seasoned saxophonist, depending on market volatility. These bands are typically positioned two standard deviations away from the SMA, a statistical measurement that shouts ’normal’ about 95% of the time.
Practical Tips for Using Bollinger Bands
Here’s how to wield this tool without getting whipped by the market’s wily ways:
- Bollinger Bounce: Think of the prices touching the bands as a ball bouncing against the walls of a racquetball court. A touch of the upper band suggests the market might be overcooked, while a dalliance with the lower band might indicate a market bargain.
- The Squeeze Is On: When the bands tighten, like a boa constrictor on a diet, it often signals a sharp price move in the wings. This phenomenon, known as ‘The Squeeze,’ might just be your cue to look out for a breakout or breakdown.
Best Practices and Considerations
- Confirmation is Key: As savvy as they are, Bollinger Bands are not lone wolves; they hunt best in a pack. Combine them with other indicators like the Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD) for a fuller picture.
- Tweak the Tweakers: Feel free to fiddle with the settings, adjusting the period length or the deviation, depending on your trading tempo and temperament.
The Legendary John Bollinger
Consult the oracle himself. Mr. Bollinger, armed with a compound of mathematics, engineering, and financial nous, concocted this indicator that continues to stand the test of time, much like his eponymous bands.
Related Terms
- Standard Deviation: A measure of how spread out numbers are, it’s the statistical spice that seasons Bollinger Bands.
- Simple Moving Average (SMA): The average price over a specified number of periods, smoothing out price data to create one of the bands.
- Volatility: The drama queen of the financial world, indicating how much and how quickly the value of an asset changes.
