GlaxoSmithKline Pharmaceuticals Limited's (NSE:GLAXO) price-to-earnings (or "P/E") ratio of 41.3x might make it look like a strong sell right now compared to the market in India, where around half of the companies have P/E ratios below 24x and even P/E's below 13x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.
With earnings growth that's superior to most other companies of late, GlaxoSmithKline Pharmaceuticals has been doing relatively well. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

There's an inherent assumption that a company should far outperform the market for P/E ratios like GlaxoSmithKline Pharmaceuticals' to be considered reasonable.
Retrospectively, the last year delivered an exceptional 42% gain to the company's bottom line. The strong recent performance means it was also able to grow EPS by 142% in total over the last three years. So we can start by confirming that the company has done a great job of growing earnings over that time.
Looking ahead now, EPS is anticipated to climb by 9.0% each year during the coming three years according to the four analysts following the company. Meanwhile, the rest of the market is forecast to expand by 20% per year, which is noticeably more attractive.
With this information, we find it concerning that GlaxoSmithKline Pharmaceuticals is trading at a P/E higher than the market. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.
It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.
Our examination of GlaxoSmithKline Pharmaceuticals' analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near as much as we would have predicted. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with GlaxoSmithKline Pharmaceuticals, and understanding should be part of your investment process.
It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
