In all honesty, it is far from difficult to manage your cash than to accept a huge loss. Please take what I am saying as me wanting to help. The decision ofcoarse is up to you.
Ease is not a good reason to ignore a monetary loss. It is just as easy to estimate your return and adjust your claim accordingly. Divide by 12 and take that amount out of your check and invest it in a money market account or for that matter anywhere you wish. The entire process might take 1hr out of your year. If you have someone doing your taxes for you, tell them what you want to do and they will take care of it for you. It is either a lose lose or win win scenario. The choice is up to you.
The "small" amount that you would take out and invest would be working for you rather than decreasing in value while someone else is making money from it.
Use your money for you. All of it. If you had an extra 100K in an account waiting for you during retairement, or for an emergency, that would be a good thing, right?
