The shorts had no luck getting their games to walk the stock down to work over the last week and a half... and now stock price is marching up again. Simple when earnings come our... the stock will bump even higher. My last warning before earnings... cover or face a larger loss!
It dips after because some get in just before in speculative play... the "get in" causes a bump up. That bump up should cause shorts to cover... forcing it higher. When those get out of that speculative play... there maybe a drop, but overall we will be higher. Shorts should cover
