On this big run up it's best to take a position and hold..trying to trade in and out always proves fruitless and is a recipe for regret. I know from past experience and from countless others. Let it run up to the promised land before taking profits. Some traders are going to flip and have already blown their load and sold.. and thinking they can BS it back down to pick up more.. but the SP is only going up from here and they'll miss a lot gains. Just disregard it and focus on what's ahead -- the culmination of years of diligent work towards this game-changing platform and app.
