I have thought about this for a long time. Frankly, I don't see any reason to make the mark to market election. Main advantage would be the ability to deduct unrealized losses at December 31. However, there are two things which offset this advantage:
1) Your ability to deduct Schedule D unused carryover losses from previous years will be significantly restricted, and
2) If you are in the business of trading and are incurring consistent losses in excess of your gains, perhaps you might wish to consider an alternative trade or business.
PS: I strongly believe that a buy, sell, or hold decision on any traded security should be based on factors totally apart from tax considerations.
Perhaps you have been thinking about this in terms of your own trading and applying that to your conclusion?
Even if the "deductng of Schedule D unused carryover losses from previous year is significantly restricted", I have none.
I trade a pool of stocks frequently and in pairs. By nature, a lot of them will incur losses and in the big picture, this is irrelevant since I am pulling out far more gains than realized losses.
However, at the end of the year, without MTM status, I am losing the ability to trade these Wash Sale candidates for a month. Even worse, if this removes more of the over (or under) valued group, I'm also losing the ability to select the best pairs, thereby further limiting my potential.
As for "considering an alternative trade or business," my goal for this month is to maintain the rate of gain that I achieved last year not limit it, let alone look for another line of work that will take years to achieve what has been done in months LOL.
And though I mostly agree with you that tax considerations should not determine buy/sell/hold decisions, that is more relevant to every day investors. When you start cranking out some size, it maginfies the problem.
For example, if a series of pairs over several months generated $50,000 in gains while racking up $20,000 in losses, would you want to pay taxes on $50,000 in '08 and defer a loss of $20,000 to '09? I surely wouldn't, hence the consideration of MTM status. In reality, I had about $35,000 in realized losses in December and I don't know how much carryover loss exists from November so it's more than pocket change that I'm concerned with. Therefore tax decisions are determining my B/S/hold options.
Thanks for your comments.
