# Read This Before You Buy ZK International Group Co., Ltd. (NASDAQ:ZKIN) Because Of Its P/E Ratio

This article is for investors who would like to improve their understanding of price to earnings ratios (P/E ratios). To keep it practical, weâ€™ll show how ZK International Group Co., Ltd.â€™s (NASDAQ:ZKIN) P/E ratio could help you assess the value on offer. ZK International Group has a price to earnings ratio of 3.05, based on the last twelve months. In other words, at todayâ€™s prices, investors are paying \$3.05 for every \$1 in prior year profit.

### How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Share Price Ã· Earnings per Share (EPS)

Or for ZK International Group:

P/E of 3.05 = \$1.62 Ã· \$0.53 (Based on the trailing twelve months to March 2018.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. All else being equal, itâ€™s better to pay a low price â€” but as Warren Buffett said, â€˜Itâ€™s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.â€™

### How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. When earnings grow, the â€˜Eâ€™ increases, over time. That means even if the current P/E is high, it will reduce over time if the share price stays flat. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

ZK International Group shrunk earnings per share by 5.2% last year.

### How Does ZK International Groupâ€™s P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. If you look at the image below, you can see ZK International Group has a lower P/E than the average (8.3) in the metals and mining industry classification.

This suggests that market participants think ZK International Group will underperform other companies in its industry. Many investors like to buy stocks when the market is pessimistic about their prospects. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

The â€˜Priceâ€™ in P/E reflects the market capitalization of the company. That means it doesnâ€™t take debt or cash into account. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting ZK International Groupâ€™s P/E?

ZK International Group has net debt worth a very significant 125% of its market capitalization. If you want to compare its P/E ratio to other companies, you must keep in mind that these debt levels would usually warrant a relatively low P/E.

### The Bottom Line On ZK International Groupâ€™s P/E Ratio

ZK International Groupâ€™s P/E is 3.1 which is below average (17.1) in the US market. The P/E reflects market pessimism that probably arises from the lack of recent EPS growth, paired with significant leverage.

Investors have an opportunity when market expectations about a stock are wrong.
