Equinix is the world's largest data center REIT, operating 260+ facilities across 70+ metros globally. Its interconnection-rich colocation model creates powerful network effects and high switching costs, forming a durable competitive moat. The company is a direct beneficiary of AI infrastructure buildout, as hyperscalers and enterprises expand their digital footprints.

The stock has surged ~25% over the past 30 days, now trading near its 52-week high and well above its 50-day MA ($790), suggesting strong momentum but potential near-term overextension. The P/E of 89x appears elevated, though REIT investors should focus on AFFO multiples, which are more reasonable but still premium. EPS of $10.73 reflects heavy depreciation typical of the asset-heavy model.

Bull case: Secular demand from AI, cloud, and hybrid IT deployments; recurring revenue model with 95%+ retention rates; global scale is nearly impossible to replicate. Bear case: High valuation leaves little margin for error; rising interest rates pressure REIT valuations; capital-intensive expansion could strain returns if demand softens. Equinix remains a cornerstone data center holding, though entry at current levels requires patience.
