I'm also surprised to hear that your colleagues like you so much. In my experience, people tend not to be especially keen on their overachieving workmates. If I were sitting next to someone who despatched his work to the bosses' satisfaction in a couple of hours and then spent the rest of the day writing scripts and studying, I wouldn't feel too warmly towards him.
And finally I'm surprised that you need so much money. Isn't the point of portfolio management that you get paid quite a lot for it? Unless you are also overachieving at sowing your seeds and already have four children, then surely you can afford to take a worse paid job?
Tell your boss
Despite the above, I'm still prepared to feel sorry for you. Having too little to do is a kind of torture and is far worse than having too much to do. However, trying to get sacked isn't the option. In most countries, getting fired for doing your work badly - let alone for having your hand in the till or up someone's skirt - means you don't get a bean.
