HSBC has upgraded NVIDIA ($NVDA) to Buy with a new street-high price target of $320, citing a significantly increased total addressable market for GPUs by 2027. This target is based on a projected $351 billion in datacenter revenue for FY27, which is 36% above consensus estimates. If NVIDIA achieves $11 EPS by 2027, its forward P/E and P/S ratios would be lower than current levels, suggesting potential for future valuation expansion.
