The big move based on speculative upgrade can't last long. They could be preparing the grounds for their best customers to get out at higher price. If AMZN closes red today, that would be a big lesson to those who trade based on manipulative speculation. FPE at 170 while company losing money in a very competitive low-margin business?
If overall market goes down, I don't think PCLN would be able to buck the trend. In any case, 1500 is way too high - it is having a difficult time to get a lift and volume is not there, so old style sharp up moves are less likely. The next few days will tell if this stock has any fire under its belly - charts tell me it could revisit 1167 before it goes over the 1300 resistance level.
Dollar is strengthening again, economy is slowing down, gas prices shot up significantly, 2Q15 outlook was terrible, YHOO Finance page shows analyst estimates for EPS reduced significantly, and recent uptick came with very low volume that lacks conviction - so the question is why PCLN going up? PCLN should re-test recent low of 1167 but could fall further down to 1110. I would buy some if it fell to 1110 and at around 990 if that get to that level.
