Could you ellaborate a bit further what your main question is ? What does the "150% cost" represent? Are we talking about the costs associated with fees? That doesn't even make sense, here's some basic math:

% Commissions (fees for example ) =  Value of fee / Total investment.

Pratical example : 20 € (total purchase fee) / 1.000 € (investment) = 2 %


A 150 % cost means that you would actually have to may more fees than your investment (which doesn't make sense). Please elaborate whenever possible.
