Macro Viewpoint
Headline roulette is back. The record-setting rally on Wall Street has stalled this week, putting the S&P 500’s nine straight weekly gains at risk, as investors weigh a renewed flare-up in US-Iran hostilities with both sides reporting retaliations for earlier strikes.
Although a ceasefire was reached in early April, talks to end the conflict and reopen the Strait of Hormuz have made little progress. Oil moved sharply higher on the escalation, pulling stocks and bonds into the red as the prospect of sustained elevated energy prices and renewed inflation pressure returned to the fore.
Prime Intelligence
The index continues to be carried by a narrower group of mega-cap names than at any point in recent memory as we’ve highlighted two days ago.
Performance dispersion within equities remains elevated and correlations remain low, conditions that typically support stock selection. Yet the market continues to be driven narrowly by mega-cap Growth. Since the S&P 500 bottomed at the end of March, only 22% of stocks have kept up with the index, a sharp reversal from positive breadth earlier this year. Breadth has flipped from tailwind to headwind in 2Q.
That divergence showed up directly in fund returns. Hedge funds broadly posted gains across strategies in May, but the performance gap between categories reflected how closely each was aligned with the narrow leadership driving the index.
Fundamental long/short managers, particularly those with concentrated exposure to technology and large-cap growth, captured meaningful alpha on the long book. Macro and CTA strategies held their ground. Event driven and relative value trailed.
Key Takeaway: When only 22% of stocks keep up with the index, breadth stops being a tide that lifts all boats. Alpha still existed in May, but it was concentrated in the hands of whoever was positioned in the right names.
