The direction of investment appears to be in the opposite direction - it's the company that's doing the investments.
This is "Судя по структуре фразы". What's missing for your interpretation Andrei is
IN. You would be correct if the wording was: "We’ve never been more invested
IN as a company".
To confirm, consider a related but more clear expression: "We are fully invested". The first example that comes up for that is:
http://www.cnbc.com/id/34206953/Dubai_Fear_is_Noise_Stay_Ful...with:
"Dubai Fear is 'Noise'—Stay Fully Invested: Strategist" -- it goes on to say that market fears in Dubai are groundless and YOU as an investor should STAY INVESTED. Meaning don't start panic selling, hold on to YOUR investments in that market.
Another:
http://www.businessinsider.com/sell-in-may-and-go-away-2011-..."We are fully invested today but may cut back at any time" -- Once again - it's
them who are doing the investment, they are not invested
in.
The list goes on.
