Is Biogen under- or over-valued?

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

Biogen's P/E ratio

Biogen's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 11x. In other words, Biogen shares trade at around 11x recent earnings.

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

Biogen's PEG ratio

Biogen's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 6.2424. 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 Biogen's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.

Biogen's EBITDA

Biogen's EBITDA (earnings before interest, taxes, depreciation and amortisation) is US$5.1 billion (£3.7 billion).

The EBITDA is a measure of a Biogen's overall financial performance and is widely used to measure a its profitability.

Shorting Biogen shares

There are currently 3.6 million Biogen shares held short by investors – that's known as Biogen's "short interest". This figure is 8% down from 4.0 million last month.

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

Biogen's "short interest ratio" (SIR)

Biogen's "short interest ratio" (SIR) is the quantity of Biogen shares currently shorted divided by the average quantity of Biogen shares traded daily (recently around 1.3 million). Biogen's SIR currently stands at 2.84. In other words for every 100,000 Biogen shares traded daily on the market, roughly 2840 shares are currently held short.

However Biogen's short interest can also be evaluated against the total number of Biogen shares, or, against the total number of tradable Biogen shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Biogen's short interest could be expressed as 0.02% of the outstanding shares (for every 100,000 Biogen shares in existence, roughly 20 shares are currently held short) or 0.0241% of the tradable shares (for every 100,000 tradable Biogen shares, roughly 24 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 Biogen.

Biogen share dividends

We're not expecting Biogen to pay a dividend over the next 12 months.

Have Biogen's shares ever split?

Biogen's shares were split on a 3:1 basis on 17 January 2001. So if you had owned 1 share the day before before the split, the next day you'd have owned 3 shares. This wouldn't directly have changed the overall worth of your Biogen shares – just the quantity. However, indirectly, the new 66.7% lower share price could have impacted the market appetite for Biogen shares which in turn could have impacted Biogen's share price.
