No, not new to this. Many factors come into play besides holding WDRP for a year as you now pointed out. It's the overall income, not just securities income. I suspect the amount your trading is significantly less than what I am doing. Maybe the tax rate will change next year - 20% maybe??
If you sell your shares less then a year from purchase and you make such and such amount, the taxation on your gains is going to be much larger then if you were to sell less then a year. . . unless you are trading out of your IRA.
Are you new to this? You should be getting several FREE trades a month just for maintaining a certain balance.
Plus your spending a caboodle on trade commissions buying and selling.
