# Does HomeServe plc’s (LON:HSV) PE Ratio Signal A Selling Opportunity?

I am writing today to help inform people who are new to the stock market and want to begin learning about how to value company based on its current earnings and what are the drawbacks of this method.

HomeServe plc (LON:HSV) trades with a trailing P/E of 30.6, which is higher than the industry average of 22. Though this might seem to be a negative, you might change your mind after I explain the assumptions behind the P/E ratio. Today, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio.

### Breaking down the P/E ratio

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. By comparing a stock’s price per share to its earnings per share, we are able to see how much investors are paying for each dollar of the company’s earnings.

P/E Calculation for HSV

Price-Earnings Ratio = Price per share ÷ Earnings per share

HSV Price-Earnings Ratio = £9.24 ÷ £0.302 = 30.6x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to HSV, such as company lifetime and products sold. A common peer group is companies that exist in the same industry, which is what I use. HSV’s P/E of 30.6 is higher than its industry peers (22), which implies that each dollar of HSV’s earnings is being overvalued by investors. This multiple is a median of profitable companies of 24 Commercial Services companies in GB including Mortice, Communisis and Babcock International Group. You could think of it like this: the market is pricing HSV as if it is a stronger company than the average of its industry group.

### A few caveats

Before you jump to conclusions it is important to realise that there are assumptions in this analysis. The first is that our “similar companies” are actually similar to HSV. If not, the difference in P/E might be a result of other factors. For example, HomeServe plc could be growing more quickly than the companies we’re comparing it with. In that case it would deserve a higher P/E ratio. Of course, it is possible that the stocks we are comparing with HSV are not fairly valued. So while we can reasonably surmise that it is optimistically valued relative to a peer group, it might be fairly valued, if the peer group is undervalued.

### What this means for you:

If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to rebalance your portfolio and reduce your holdings in HSV. But keep in mind that the usefulness of relative valuation depends on whether you are comfortable with making the assumptions I mentioned above. Remember that basing your investment decision off one metric alone is certainly not sufficient. There are many things I have not taken into account in this article and the PE ratio is very one-dimensional. If you have not done so already, I urge you to complete your research by taking a look at the following:

Hedge fund managers like David Einhorn, Bill Ackman, or Carl Icahn became billionaires through reaping large profits for their investors, which is why piggybacking their stock picks may provide us with significant returns as well. Many hedge funds, like Paul Singer's Elliott Management, are pretty secretive, but we can still get some insights by analyzing their quarterly 13F filings. One of the most fertile grounds for large abnormal returns is hedge funds' most popular small-cap picks, which are not so widely followed and often trade at a discount to their intrinsic value.

### Bank of America declares “the end of the 60-40” standard portfolio

Investors have long been told that the ideal portfolio should carry 60% of its holdings in equities and 40% in bonds, a mix that provides greater exposure to historically superior stock returns, while also granting the diversification benefits and lower risk of fixed-income investments. But in a research note published by Bank of America Securities, titled “The End of 60/40,” portfolio strategists Derek Harris and Jared Woodward argue that “there are good reasons to reconsider the role of bonds in your portfolio,” and to allocate a greater share toward equities.

### Sanofi opens new Framingham site amid \$1.6B bet on bio-manufacturing

As one of the state's largest life science employers plots out its future, the company unveiled a \$320 million investment it hopes will give it a competitive advantage against other big pharmas. Sanofi S.A. (NYSE: SNY) opened the doors of a new 100,000-square-foot, completely digital bio-manufacturing facility in Framingham Tuesday.  Unlike standard biotech manufacturing sites — which rely on what Sanofi's Program Director Dean Morris called “tank farms” that create batches of the molecular elements used to make drugs — Sanofi's new plant continually feeds in new materials and sifts out finished products. As a result, the space is roughly a fifth of the size of comparable facilities.  Sanofi executives declined to say what products will be produced at the new facility, which is adjacent to the company's existing manufacturing sites in Framingham.
