What Is Casa Systems's (NASDAQ:CASA) P/E Ratio After Its Share Price Rocketed?

Casa Systems (NASDAQ:CASA) shares have had a really impressive month, gaining 38%, after some slippage. But shareholders may not all be feeling jubilant, since the share price is still down 50% in the last year.

All else being equal, a sharp share price increase should make a stock less attractive to potential investors. In the long term, share prices tend to follow earnings per share, but in the short term prices bounce around in response to short term factors (which are not always obvious). So some would prefer to hold off buying when there is a lot of optimism towards a stock. 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 ratio means that investors have a high expectation about future growth, while a low P/E ratio means they have low expectations about future growth.

The company could surprise by performing better than average, in the future. I would further inform my view by checking insider buying and selling., among other things.

How Growth Rates Impact P/E Ratios

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

Casa Systems's earnings per share fell by 74% in the last twelve months. And over the longer term (5 years) earnings per share have decreased 21% annually. This could justify a pessimistic P/E.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. That means it doesn't take debt or cash into account. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

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.
