Key Insights

  • Using data from analyst forecasts alongside ownership research, one can better assess the future performance of a company

To get a sense of who is truly in control of TGS ASA (OB:TGS), it is important to understand the ownership structure of the business. The group holding the most number of shares in the company, around 55% to be precise, is institutions. That is, the group stands to benefit the most if the stock rises (or lose the most if there is a downturn).

And so it follows that institutional investors was the group most impacted after the company's market cap fell to kr16b last week after a 5.3% drop in the share price. The recent loss, which adds to a one-year loss of 34% for stockholders, may not sit well with this group of investors. Also referred to as "smart money", institutions have a lot of sway over how a stock's price moves. Hence, if weakness in TGS' share price continues, institutional investors may feel compelled to sell the stock, which might not be ideal for individual investors.

What Does The Institutional Ownership Tell Us About TGS?

Institutional investors commonly compare their own returns to the returns of a commonly followed index. So they generally do consider buying larger companies that are included in the relevant benchmark index.

But we can't rely on that fact alone since institutions make bad investments sometimes, just like everyone does. If multiple institutions change their view on a stock at the same time, you could see the share price drop fast. It's therefore worth looking at TGS' earnings history below. Of course, the future is what really matters.

Institutional investors own over 50% of the company, so together than can probably strongly influence board decisions. We note that hedge funds don't have a meaningful investment in TGS.

Insider Ownership Of TGS

The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. Management ultimately answers to the board. However, it is not uncommon for managers to be executive board members, especially if they are a founder or the CEO.

I generally consider insider ownership to be a good thing. However, on some occasions it makes it more difficult for other shareholders to hold the board accountable for decisions.

Our data suggests that insiders own under 1% of TGS ASA in their own names. It is a pretty big company, so it would be possible for board members to own a meaningful interest in the company, without owning much of a proportional interest. In this case, they own around kr48m worth of shares (at current prices). Arguably, recent buying and selling is just as important to consider.
