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 8x. In other words, Biogen shares trade at around 8x 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.

However, Biogen's P/E ratio is best considered in relation to those of others within the drug manufacturers-general industry or those of similar companies.

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.

However, it's sensible to consider Biogen's PEG ratio in relation to those of similar companies.

Biogen's EBITDA

Biogen's EBITDA (earnings before interest, taxes, depreciation and amortisation) is a whopping $7.1 billion (£5.3 billion).

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

To put Biogen's EBITDA into context you can compare it against that of similar companies.

How to short and sell Biogen shares

  1. Create a CFD or spread betting account.
  2. Search for the stock code. E.g. "BIIB.US"
  3. Choose your position size.
  4. Select "sell" rather than "buy".
  5. Confirm your position and keep tabs on it. You may wish to set limits on your position.

There are currently 3.8 million Biogen shares held short by investors – that's known as Biogen's "short interest". This figure is 7% down from 4.1 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 2.94. In other words for every 100,000 Biogen shares traded daily on the market, roughly 2940 shares are currently held short.

To gain some more context, you can compare Biogen's short interest ratio against those of similar companies.

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 0.03% of the outstanding shares (for every 100,000 Biogen shares in existence, roughly 30 shares are currently held short) or 0.0251% of the tradable shares (for every 100,000 tradable Biogen shares, roughly 25 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.

Environmental, social and governance (known as ESG) criteria are a set of three factors used to measure the sustainability and social impact of companies like Biogen.

Have Biogen's shares ever split?

Biogen's shares were split on a 3:1 basis on 18 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.

Biogen share price volatility

Over the last 12 months, Biogen's shares have ranged in value from as little as $223.25 up to $350.24. 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 (NASDAQ average) beta is 1, while Biogen's is 0.4924. This would suggest that Biogen's shares are less volatile than average (for this exchange).

To put Biogen's beta into context you can compare it against those of similar companies.
