A month has gone by since the last earnings report for Monolithic Power (MPWR). Shares have lost about 9.4% in that time frame, underperforming the S&P 500.

Will the recent negative trend continue leading up to its next earnings release, or is Monolithic due for a breakout? Before we dive into how investors and analysts have reacted as of late, let's take a quick look at its most recent earnings report in order to get a better handle on the important catalysts.

Monolithic Power Q4 Earnings & Revenues Beat Estimates
