Will - that is indeed an archaic definition of "invest". All our efforts are for naught then!
I will be in the USA tomorrow (Texas to be exact) on CFA Institute volunteer work and look forward to observing some more entertaining politics. In certain respects some presidential candidates' antics trump anything I have seen before.
Two other unusual words that can be useful in investment commentaries: "shellac" and "otiose".
Cheers
