Methinks you're applying too narrow a meaning to the word "investor". The distinctions you suggest are often controversial, rarely important, and hardly ever of anything but semantic interest to an academic.
In everyday use, the term is used increasingly to describe any person - be they natural, corporate, or legally ficticious - who exchanges cash for an asset and expects the asset to increase in value. After some indeterminate time, they swap the asset back into cash
Some "investments" stay longer in the asset phase, others not so long. It depends on the investor's expectation and how quickly an asset has done its job of increasing its value.
I have stayed invested in some assets for years; others I have sold after a couple of minutes.
Does one make me an investor? The other a trader? I'm still the same person and couldn't care less what label is pinned on what I do.
Sure, it would be more truthful if those morning spruikers and editors were saying/ writing something like: "Our guess is as good as yours; we think the ASX 200 will gain about 1% today because an official from {Bundesbank/ Fed/ Goldman-Sachs...} said things weren't as bad as they looked yesterday. The {DAX/ FTSE/ Dow...} rose, which usually means our market will rise as well."
Now
THAT would be understandable: reporting who said what, and explaining the logic behind a simple conclusion. Which is precisely why no self-respecting editor would publish anything that way.

Financial matters must be mysterious, and the talking heads/ writers make themselves look better if they're on first-name basis with those elusive and all-knowing VIP "Investors".
