Very difficult question

Can we say: "He has many foreign investment markets,"

to mean: "He has control/access over many foreign investment markets"?

In informal speech, in formal speech?

Moreover, is "He has many foreign investment markets" a metaphor, ellipsis?

What about "He took the market"? Is that a metaphor, ellipsis?

For the first one, you woiuld say "He has many investments in foreign markets"  Or, "He has investments in many foreign markets".

The first one would be more accurate if he has made a lot of investments, but not in a lot of different places.  The second would be correct if he has made investments in many  different countries. Either one works, though.

The second two don't really work….You might say,"He controls many foreign investment markets", if he actually does have control over them. 

I'm not sure what you mean by,"He took the market" at all, really.   Does that mean he has the most shares and therefore has control?  Or that he's made a lot of money from his investments?  I'm not really sure….
