Beta in Forex
A clear definition of Beta, with practical context for reading markets and making better trading decisions.
Definition
Beta measures how sensitive an investment's returns have been relative to movements in a chosen market benchmark.
How to Read Beta
A beta near 1 suggests the investment has historically moved by a similar magnitude to the benchmark. A beta above 1 suggests greater sensitivity, while a beta below 1 suggests lower sensitivity. A negative beta indicates a tendency to move in the opposite direction, although stable negative betas are uncommon.
Limitations
Beta is based on historical relationships. It can change over time and depends on the benchmark and sample period. It measures relative movement, not whether an investment is “good,” “safe,” or guaranteed to behave the same way in the future.
Key Takeaway
Beta is a relative sensitivity measure. It compares an asset's historical movement with a benchmark rather than predicting its next move.
