$Advanced Micro Devices(AMD)$ There's a major contradiction between HSBC's downgrade justification and RBC Capital's market perform outlook. RBC Capital argues supply constraints may limit AMD's growth in the short term, then HSBC uses a sales slowdown based on product inventory increases. Lisa Su made it clear in past conference calls that AMD had prepared for the memory shortage. She also made it clear that the company was firing on all cylinders regarding projected sales and revenue increases. It looks like HSBC decided to jump on the supply constraint bandwagon argument presented by RBC, but missed the mark on the details. To me, the HSBC downgrade feels like a typical example of the pre-earnings fear mongering these investment firms engage in to benefit their own trading schemes.
