Best practice
When describing patterns or trends that aren't consistently upward or downward, use "fluctuating change" to convey the up-and-down movement.
Common error
Be careful not to use "fluctuating change" when "change" alone sufficiently captures the meaning. Overusing "fluctuating" can make your writing sound repetitive. If the context already implies variability, just use "change".
