Is GlaxoSmithKline under- or over-valued?

Valuing GlaxoSmithKline stock is incredibly difficult, and any metric has to be viewed as part of a bigger picture of GlaxoSmithKline's overall performance. However, analysts commonly use some key metrics to help gauge the value of a stock.

GlaxoSmithKline's P/E ratio

GlaxoSmithKline's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 35x. In other words, GlaxoSmithKline shares trade at around 35x recent earnings.

That's relatively high compared to, say, the trailing 12-month P/E ratio for the NASDAQ 100 at the end of 2019 (27.29). The high P/E ratio could mean that investors are optimistic about the outlook for the shares or simply that they're over-valued.

GlaxoSmithKline's PEG ratio

GlaxoSmithKline's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 8.1242. A low ratio can be interpreted as meaning the shares offer better value, while a higher ratio can be interpreted as meaning the shares offer worse value.

The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into GlaxoSmithKline's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.

Shorting GlaxoSmithKline shares

There are currently 14.2 million GlaxoSmithKline shares held short by investors – that's known as GlaxoSmithKline's "short interest". This figure is 8.4% up from 13.1 million last month.

There are a few different ways that this level of interest in shorting GlaxoSmithKline shares can be evaluated.

GlaxoSmithKline's "short interest ratio" (SIR)

GlaxoSmithKline's "short interest ratio" (SIR) is the quantity of GlaxoSmithKline shares currently shorted divided by the average quantity of GlaxoSmithKline shares traded daily (recently around 4.3 million). GlaxoSmithKline's SIR currently stands at 3.31. In other words for every 100,000 GlaxoSmithKline shares traded daily on the market, roughly 3310 shares are currently held short.

However GlaxoSmithKline's short interest can also be evaluated against the total number of GlaxoSmithKline shares, or, against the total number of tradable GlaxoSmithKline shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case GlaxoSmithKline's short interest could be expressed as 0.01% of the outstanding shares (for every 100,000 GlaxoSmithKline shares in existence, roughly 10 shares are currently held short) or 0% of the tradable shares (for every 100,000 tradable GlaxoSmithKline shares, roughly 0 shares are currently held short).

Such a low SIR usually points to an optimistic outlook for the share price, with fewer people currently willing to bet against GlaxoSmithKline.

GlaxoSmithKline share dividends

71%

Dividend payout ratio: 70.68% of net profits

Recently GlaxoSmithKline has paid out, on average, around 70.68% of net profits as dividends. That has enabled analysts to estimate a "forward annual dividend yield" of 6.13% of the current stock value. This means that over a year, based on recent payouts (which are sadly no guarantee of future payouts), GlaxoSmithKline shareholders could enjoy a 6.13% return on their shares, in the form of dividend payments. In GlaxoSmithKline's case, that would currently equate to about $1.058 per share.

GlaxoSmithKline's payout ratio would broadly be considered high, and as such this stock could appeal to those looking to generate an income. Bear in mind however that companies should normally also look to re-invest a decent amount of net profits to ensure future growth.

GlaxoSmithKline's most recent dividend payout was on 8 April 2021. The latest dividend was paid out to all shareholders who bought their shares by 18 February 2021 (the "ex-dividend date").

Have GlaxoSmithKline's shares ever split?

GlaxoSmithKline's shares were split on a 2:1 basis on 12 November 1991. So if you had owned 1 share the day before before the split, the next day you'd have owned 2 shares. This wouldn't directly have changed the overall worth of your GlaxoSmithKline shares – just the quantity. However, indirectly, the new 50% lower share price could have impacted the market appetite for GlaxoSmithKline shares which in turn could have impacted GlaxoSmithKline's share price.

GlaxoSmithKline share price volatility

Over the last 12 months, GlaxoSmithKline's shares have ranged in value from as little as US$29.7795 up to US$41.1067. A popular way to gauge a stock's volatility is its "beta".

Beta is a measure of a share's volatility in relation to the market. The market (NYSE average) beta is 1, while GlaxoSmithKline's is 0.3633. This would suggest that GlaxoSmithKline's shares are less volatile than average (for this exchange).
