A Sliding Share Price Has Us Looking At CDW Corporation's (NASDAQ:CDW) P/E Ratio

To the annoyance of some shareholders, CDW (NASDAQ:CDW) shares are down a considerable 33% in the last month. Even longer term holders have taken a real hit with the stock declining 6.6% in the last year.

Assuming nothing else has changed, a lower share price makes a stock more attractive to potential buyers. While the market sentiment towards a stock is very changeable, in the long run, the share price will tend to move in the same direction as earnings per share. The implication here is that long term investors have an opportunity when expectations of a company are too low. Perhaps the simplest way to get a read on investors' expectations of a business is to look at its Price to Earnings Ratio (PE Ratio). A high P/E implies that investors have high expectations of what a company can achieve compared to a company with a low P/E ratio.

How Does CDW's P/E Ratio Compare To Its Peers?

We can tell from its P/E ratio of 18.00 that there is some investor optimism about CDW. The image below shows that CDW has a higher P/E than the average (14.0) P/E for companies in the electronic industry.

That means that the market expects CDW will outperform other companies in its industry. Clearly the market expects growth, but it isn't guaranteed. So further research is always essential. I often monitor director buying and selling.

How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. Earnings growth means that in the future the 'E' will be higher. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Most would be impressed by CDW earnings growth of 19% in the last year. And its annual EPS growth rate over 5 years is 29%. So one might expect an above average P/E ratio.

Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. That means it doesn't take debt or cash into account. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

CDW's Balance Sheet

Net debt is 28% of CDW's market cap. While that's enough to warrant consideration, it doesn't really concern us.

The Bottom Line On CDW's P/E Ratio

CDW has a P/E of 18.0. That's higher than the average in its market, which is 13.3. The company is not overly constrained by its modest debt levels, and its recent EPS growth very solid. So on this analysis it seems reasonable that its P/E ratio is above average. What can be absolutely certain is that the market has become significantly less optimistic about CDW over the last month, with the P/E ratio falling from 26.9 back then to 18.0 today. For those who prefer to invest with the flow of momentum, that might be a bad sign, but for a contrarian, it may signal opportunity.
