3. The extreme of his stock portfolio translated into a display of emotion: on lucrative days he felt ecstatic; on losing days he acted despondent. aggressiveness...consistent
nature...passionate
position...crazy
volatility...mercurial
variation...pacific

volatility...mercurial

Explanation:

The second part of the sentence helps us infer its meaning; it denotes changes in one's mood. From the first part of the sentence, then, we can see that these mood swings mimicked changes in his stock portfolio.

Basically, depending on the balance on his stock portfolio, the person was either ecstatic either depressed.

Now that we've infered the context of the sentence, it's not hard to see that the word pair we're looking for has to do something with changes, variability, inconsistency, tendency to easily fluctuate in short period of the time.

The only pair that could fit in this description is "volatility...mercurial".

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
