Green Thumb looks like a rare opportunity to grow your marijuana profits. That news sent Green Thumb stock rocketing more than 15% yesterday, as investors bet the president would soon announce official backing for medical marijuana -- or even for legalizing marijuana in general. The momentum carried over into this morning, spurred by a well-timed press release from Green Thumb announcing the open of its latest RISE marijuana dispensary in Lebanon, Pa.For those keeping score at home, that's about 20% of gains for Green Thumb stock in barely 24 hours. Is Green Thumb Industries stock a sell? While it's never easy to predict what's next on President Trump's agenda, if legalization is on the table, this could be a great price at which to get into Green Thumb stock.
