- Monolithic Power (MPWR) is a Great Momentum Stock: Should You Buy?
May 12, 2026
Momentum investing is all about the idea of following a stock's recent trend, which can be in either direction. In the "long context," investors will essentially be "buying high, but hoping to sell even higher." And for investors following this methodology, taking advantage of trends in a stock's price is key; once a stock establishes a course, it is more than likely to continue moving in that direction. The goal is that once a stock heads down a fixed path, it will lead to timely and profitable trades.
Even though momentum is a popular stock characteristic, it can be tough to define. Debate surrounding which are the best and worst metrics to focus on is lengthy, but the Zacks Momentum Style Score, part of the Zacks Style Scores, helps address this issue for us.
Below, we take a look at Monolithic Power (MPWR), a company that currently holds a Momentum Style Score of A. We also talk about price change and earnings estimate revisions, two of the main aspects of the Momentum Style Score.
It's also important to note that Style Scores work as a complement to the Zacks Rank, our stock rating system that has an impressive track record of outperformance. Monolithic Power currently has a Zacks Rank of #2 (Buy). Our research shows that stocks rated Zacks Rank #1 (Strong Buy) and #2 (Buy) and Style Scores of "A or B" outperform the market over the following one-month period.

Set to Beat the Market?
In order to see if MPWR is a promising momentum pick, let's examine some Momentum Style elements to see if this chipmaker holds up.
Looking at a stock's short-term price activity is a great way to gauge if it has momentum, since this can reflect both the current interest in a stock and if buyers or sellers have the upper hand at the moment. It's also helpful to compare a security to its industry; this can show investors the best companies in a particular area.
For MPWR, shares are up 1.1% over the past week while the Zacks Semiconductor - Analog and Mixed industry is up 5.1% over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 21.05% compares favorably with the industry's 39.42% performance as well.
While any stock can see a spike in price, it takes a real winner to consistently outperform the market. Over the past quarter, shares of Monolithic Power have risen 41.8%, and are up 134.21% in the last year. In comparison, the S&P 500 has only moved 7.12% and 32.44%, respectively.
Story Continues
Investors should also pay attention to MPWR's average 20-day trading volume. Volume is a useful item in many ways, and the 20-day average establishes a good price-to-volume baseline; a rising stock with above average volume is generally a bullish sign, whereas a declining stock on above average volume is typically bearish. MPWR is currently averaging 635,660 shares for the last 20 days.
Earnings Outlook
The Zacks Momentum Style Score encompasses many things, including estimate revisions and a stock's price movement. Investors should note that earnings estimates are also significant to the Zacks Rank, and a nice path here can be promising. We have recently been noticing this with MPWR.
Over the past two months, 8 earnings estimates moved higher compared to none lower for the full year. These revisions helped boost MPWR's consensus estimate, increasing from $21.63 to $24.05 in the past 60 days. Looking at the next fiscal year, 8 estimates have moved upwards while there have been no downward revisions in the same time period.
Bottom Line
Taking into account all of these elements, it should come as no surprise that MPWR is a #2 (Buy) stock with a Momentum Score of A. If you've been searching for a fresh pick that's set to rise in the near-term, make sure to keep Monolithic Power on your short list.

- Can ON's AI Data Center Momentum Drive a Multi-Year Growth Cycle?
May 11, 2026
Artificial intelligence is rapidly becoming one of the strongest growth engines for ON Semiconductor Corporation ON. The company’s latest quarterly results suggest this momentum could extend well beyond 2026.
Management highlighted that AI data center revenues surged more than 30% sequentially in the first quarter, far exceeding internal expectations, as adoption expanded across hyperscalers and multiple XPU platforms. The company now expects AI data center revenues to double year over year in 2026.
ON is benefiting from rising power demands inside modern AI infrastructure. As data centers transition toward higher power density and advanced architectures, the need for efficient power conversion and management solutions is increasing sharply.
The company has built a broad portfolio that includes silicon carbide, gallium nitride, intelligent power modules and mixed signal technologies. This diverse offering positions ON well to benefit from growing AI infrastructure demand. Its solutions support the entire AI power chain, ranging from the electrical grid to processors inside data centers.
Management also emphasized that ON is gaining traction with leading hyperscalers and power supply partners, including collaborations tied to next-generation 800-volt power systems. These opportunities are expanding beyond servers into adjacent markets such as energy storage systems and microgrids, creating what executives described as an AI halo effect.
The company’s restructuring and portfolio optimization efforts are beginning to improve profitability alongside revenue growth. Gross margin expanded for the third straight quarter, while management projected continued margin improvement through the remainder of 2026.
Although automotive and industrial recovery remains gradual, ON’s growing exposure to AI infrastructure appears capable of supporting a longer-term growth cycle driven by rising global demand for efficient power solutions.
Peers Expanding AI Power Semiconductor Capabilities
Infineon Technologies AG IFNNY is emerging as a major competitor in AI power infrastructure through its strong portfolio of silicon carbide and power management solutions. The company is expanding its exposure to AI servers, renewable energy and industrial power systems, areas witnessing rising demand as hyperscalers build larger data centers. Infineon is also increasing investments in gallium nitride technologies to improve power efficiency and thermal performance for next-generation AI workloads.
Monolithic Power Systems Inc. MPWR is another key rival benefiting from the AI boom. The company has gained traction in power-management chips for GPUs and AI accelerators. Monolithic Power Systems’ integrated solutions help improve efficiency, reduce power losses and support higher rack densities in AI servers. As AI accelerator deployments continue to rise globally, Monolithic Power Systems is expected to remain a strong competitor to ON in the expanding AI data center-power market.

- A Look At Monolithic Power Systems (MPWR) Valuation After A Strong Multi‑Month Share Price Run
May 10, 2026
Get insights on thousands of stocks from the global community of over 7 million individual investors at Simply Wall St.
Why Monolithic Power Systems is on investors’ radar today
Monolithic Power Systems (MPWR) is drawing fresh attention after a sharp move in its share price, with the stock showing a 32.3% gain over the past month and 28.1% over the past 3 months.
See our latest analysis for Monolithic Power Systems.
That surge sits within a strong run, with a 68.3% year to date share price return and a very large 5 year total shareholder return of 433.57%. This suggests momentum remains strong despite the recent 1 day pullback.
If you are watching how semiconductor demand is reshaping markets, it could be a good time to broaden your search with 40 AI infrastructure stocks
MPWR now trades at US$1,575.96 after a strong run, while sell side price targets sit around US$1,797. With revenue and net income growth in the mid 10s to low 20s, is this still an opportunity to consider or is the market already pricing in that growth?
Most Popular Narrative: 11.2% Overvalued
Against the latest close at $1,575.96, the most widely followed fair value narrative of $1,417.57 implies the stock is pricing in a premium, and sets up a debate over how much future growth is already reflected.
MPS has expanded its manufacturing and supply chain capacity to $4 billion in annual revenue, with significant diversification outside China. This positions it to gain share, secure supply for customers in a geopolitically sensitive environment, and take advantage of rising semiconductor content in end devices, all of which may support higher revenues and margins in future years.
Read the complete narrative.
Want to see what justifies that premium tag? The narrative leans on strong revenue compounding, rising margins and a richer future earnings multiple than many sector peers.
Result: Fair Value of $1,417.57 (OVERVALUED)
Have a read of the narrative in full and understand what's behind the forecasts.
However, there are clear risks, including reliance on optimistic AI data center and automotive assumptions, as well as higher forward P/E multiples that could magnify any disappointment in execution.
