Non-Fluctuating The characteristic of constancy in a security or measurement's value, rate of change or other metric. Investopedia Says: If a security's return is non-fluctuating, it is a fixed-rate asset which has a constant yield, such as a government-issued debenture. However, the market price of the debenture will fluctuate as interest rates change. Conversely, common stock of a public corporation is more likely to fluctuate in both dividend yield and market price.
