You've carefully neglected to describe your risk tolerence and investement objectives.
Fundamentally, there are three types of approaches to how someone cares for their money. There are investors, traders and speculators. I rarely see investors, who by definition are concerned about long term capital appreciation, take speculative risk with even relatively small portions of their portfolios.
Even if you are the type of person who is comfortable with plunking this kind of money on a roll of the dice at Las Vegas or Atlantic City the potential return is several time your bet in a controlled game with known odds.
I suspect from your albeit brief description of your situation, that you are not a desciplined investor. I further suspect that you lack any successful commodity investing experience.
Your current holdings are near 20 year highs with further appreciation a crap shoot at best. You didn't address the issue of an exit strategy, so I suspect you don't have one.
I also don't know if you would ride a downturn in the market to the bottom before bailing out as is typical of someone who jumps in near the top of a market.
By siginifying that this is "mad money" you seem eager to "let 'er rip" and lose most of it with little other than emotion as justification.
My advice is to at least get "comped" by a casino for air fare, hotel room and a short decent vacation for your money.
WOW, another grouch who cares more about making a name in a thread than offering someone courteous advice. If you do not appreciate my questions, do not reply.
I sense a little jealousy that I can afford to just let it rip. I have made my money by working hard all of my life. Not by playing the market. So I may be a little naive. But I do not need to get a lecture from someone when all I am asking for is opinions.
I cannot believe how the manners here have degraded over the last year or two.
