# The Nominal Model

### The nominal model is our goto reference point for a phasing analysis and is the bedrock of a standard Hurst cycles approach. Learn more in this article!

# Modelling Markets

Throughout Sigma-L readers will find references to ‘nominal’ cycles. What does this mean? Hurst coalesced his spectral work in ‘Profit Magic for Stock Transaction Timing’ into a concise and easily referenced ‘model’ for **average wavelengths of components in financial markets**, most notably stockmarkets, but research and experience shows valid utility in other markets.

This model consists of several entries; from the 18 year component down to the 5 day component. Although the model was somewhat more populated in Hurst’s original work the classic version we use frequently today was introduced in the Cycles Course and attempted to simplify the lineup for practical trading purposes. Let’s take a look at it below.
