What I heard has nothing to do with Trump tax reform. I heard that there is a 15% extra penalty for investments that make over 1 million profit and are cashed in less than 1 year, which would put around 40-45% on uncle Sam's hand (I rough estimate). If you cash this after 1 year, there is no this 15% penalty. I heard this 1 year period has changed to 6 months recently.
