49%? What country is that ?
The maximum you would pay is 39% assuming you were in the highest tax bracket in the USA for short term.
If you want to do it the smart way, the reason people keep a "core" position is for the "pop" dream, and also because of taxes.
If you sell 1/3 or 1/2 of your position every time it pops 20% or more, which has happened about twice a year for the last 3 years. You will almost always have a batch of shares that have been in the cooker for at least one year. So you are really only paying 15% in taxes.
So once again, if you are missing the 20% pops, there is no reason for that.
If you are really aggressive, just open a trading account using your nieces and nephews that are in school and have no income. They can pay as low as 10% tax on short term, and are allowed to gift you the money tax free.
Do everything in 15k amounts if your crazy and hate taxes.
