Pinning Down Monolithic Power Systems, Inc.'s (NASDAQ:MPWR) P/S Is Difficult Right Now

With a price-to-sales (or "P/S") ratio of 21.5x Monolithic Power Systems, Inc. (NASDAQ:MPWR) may be sending very bearish signals at the moment, given that almost half of all the Semiconductor companies in the United States have P/S ratios under 5x and even P/S lower than 2x are not unusual. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

How Has Monolithic Power Systems Performed Recently?

Monolithic Power Systems could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. One possibility is that the P/S ratio is high because investors think this poor revenue performance will turn the corner. However, if this isn't the case, investors might get caught out paying too much for the stock.

Keen to find out how analysts think Monolithic Power Systems' future stacks up against the industry? In that case, our free report is a great place to start.

What Are Revenue Growth Metrics Telling Us About The High P/S?

In order to justify its P/S ratio, Monolithic Power Systems would need to produce outstanding growth that's well in excess of the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 2.1%. Still, the latest three year period has seen an excellent 96% overall rise in revenue, in spite of its unsatisfying short-term performance. So we can start by confirming that the company has generally done a very good job of growing revenue over that time, even though it had some hiccups along the way.

Looking ahead now, revenue is anticipated to climb by 19% per year during the coming three years according to the analysts following the company. With the industry predicted to deliver 27% growth each year, the company is positioned for a weaker revenue result.

In light of this, it's alarming that Monolithic Power Systems' P/S sits above the majority of other companies. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as this level of revenue growth is likely to weigh heavily on the share price eventually.

The Key Takeaway

Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Despite analysts forecasting some poorer-than-industry revenue growth figures for Monolithic Power Systems, this doesn't appear to be impacting the P/S in the slightest. Right now we aren't comfortable with the high P/S as the predicted future revenues aren't likely to support such positive sentiment for long. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
