Market ReportEquitiesPrivate MarketsInformation Technology
The S&P 500 has reached a new all-time high above 7500, fueled by intense momentum in AI semis and a rebound in retail trading activity. Despite narrow market breadth, institutional and retail demand remains strong, supported by robust Q1 corporate earnings growth of 17%.
Key Takeaways
- 1.The market is experiencing a significant momentum chase in AI-related stocks, with institutional investors being 'stopped into' the tape as buyers despite narrow breadth.
- 2.Retail trading activity has inflected higher, with volumes up 28% since mid-April, partly driven by less stringent margin requirements for day traders.
- 3.Hedge funds are heavily concentrated in Information Technology, with allocations reaching the 100th percentile for gross and 99th for net exposure over a five-year period.
