You all are missing the point...he has nothing left to gain in the trade. Nada. Zilch. Zippo. He is applying an investor mindset to a trading vehicle. He is only holding for tax purposes, not for any additional gain. He is willing to risk reducing his gains just to try to hold this for one year. There is more upside potential at this point than downside. Is it "smart" to hold it for the reason he says. That lends more credence to the argument that he is an investor who got lucky. A trader would never hold for that reason when the risk of holding is growing daily.
JMO and good luck.
PS: I gave my accountant instructions long ago to handle all my trades as income. Charities and business losses are the tax breaks.
