Riversrun, I think that your concerns over Dems taxation policy is overblown. Corporate leaders favor Dem minimal control over Congress. Please remember that the stock market always does better under the Dems (Clinton, Obama) than Republicans (Bush, Tr**p). Look it up.
And I just heard on Bloomberg that corporate leaders favor Dems control. The stimulus provided by Dems, if they have control, will be far more important for moving markets than fears of a tax cut. Besides, having only 50 seats in the Senate, with Republicans holding 50 will be check enough on taxation policy. Do you recall what a tough time Obama had with 59 Senators?
In either scenario, pot stocks will flourish, so it only matters a little bit. Good luck in your trading.
