I made an investing mistake many (eight?) years ago. Specifically, I invested a very large sum of money in a certain triple leveraged ETF (the asset has not yet been sold, but the value has decreased to maybe one 8th or 5th of the original amount). I thought the risk involved was the volatility--I didn't realize that due to the nature of the asset the value would be constantly decreasing towards zero!
Anyhow, my question is what to do next? The complicating factor is that I have since moved out of the United States and am living abroad (i.e. Japan). I am permanent resident of my host country, I have a steady salary that is paid by a company incorporated in my host country, and pay taxes to the host government. I file a tax return to the U.S. Government each year, but all my income is excluded so I do not pay any taxes. In this way, I do not think that I can write anything off on my U.S. tax return. Also, I have absolutely no idea if I would be able to write off any losses on my Japanese tax return (I've entrusted all the family tax issues to my wife). Would this be possible? Are there any other available options (that would not involve having to tell my wife about the loss, which would be inevitable if I were to go the tax write-off route in Japan)?
If I continue to hold onto this asset the value will decrease lower and lower. Any suggestions as to what to do?
