Citigroup strategists say the focus moving forward will be on data
Federal Reserve chief Kevin Warsh may be leading a more hawkish central bank. Citigroup has an idea for how to play that.
The trading week is off to a positive start as tensions appear to be cooling a bit between the U.S. and Iran. Investors are also awaiting earnings from Meta, Microsoft, Amazon and Apple, with heavy attention on the state of artificial-intelligence spending from those tech names.
Potentially stealing the spotlight this week will be a Federal Reserve meeting, with the percentage likelihood of an interest-rate hike now well into the 30s, according to CME Group's FedWatch tool, following a spike in oil prices, up from a percentage in the teens a week ago.
Our call of the day from Citigroup offers some stock advice for investors wary of a surprise hike from new Fed Chairman Kevin Warsh and/or a tone that suggests more tightening to come.
While there's no "clear consensus" for this week's meeting, a hawkish outcome poses a risk for stocks, according to a Citi team led by Stuart Kaiser, head of U.S. equity trading strategy. Even if the central bank holds steady, chances are running at more than 70% for a hike in September, so Citi doesn't see much relief coming for markets after this meeting.
As Warsh has promised less communication over interest-rate intentions, investors will have no choice but to turn their attention to data and the next meeting in two months.
Kaiser and his team said the best move to protect against a Fed hike or a more hawkish central bank is to buy put options on the iShares Russell 2000 ETF IWM. Put options allow an investor the right to sell an asset at a specified price within a set time frame and are commonly used if one suspects a selloff might be coming.
"A data-dependent [Federal Open Market Committee] and lower index weights in growth and momentum stocks should make [the Russell 2000 fund] more sensitive to reported economic data and FOMC policy decisions and behave more cyclically than in recent history," the Citi team told clients in a note published Sunday.
They explained that a June rebalance of the small-cap-focused Russell 2000 RUT has helped lower its implied volatility by fixing some distortions that made it less responsive to economic data than traditionally.
For example, over the past two years, the index was overly tilted toward growth and price momentum stocks, which made it more sensitive to rates and credit spreads over data.
Those Russell put options are now a cheaper hedge as some of the more volatile names have been stripped out. Average three-month implied volatility - that is, future expectations of volatility - of the 10 biggest stocks on the index is down to 56% from 90%, with realized volatility at just over 48% in the past month, they noted.
Implied volatility for the iShares Russell 2000 ETF is below peers.
Looking at index-weighted realized volatility across all Russell 2000 components (RTYM27), they said volatility has dropped by around five points over the last three months.
While the start of earnings season has been strong, "the bar is clearly higher," the strategists noted, with the average stock down 10 basis points on the day of an earnings report. The strategists have a preference for materials, banks, the Nasdaq-100 tracker QQQ QQQ and their basket of AI-power-generation stocks.
Citi strategists said that, while they are positive on stocks through month-end at least, investors should proceed cautiously. "Post megacap earnings, we expect stocks will be more sensitive to higher yields, rising oil and imminent equity supply ahead of a traditionally weak seasonal period," they said.

The chart
Apollo chief economist Torsten Sløk flags this chart that shows how investors shouldn't write off all software as vulnerable to AI disruption. The chart shows strongly performing security and infrastructure, which provides "critical data backbones, compute pipelines and complex protection systems that generative models actively expand rather than displace." Weaker areas are application and vertical software owing to worries about fallout from automated AI workflows. "The bottom line is that the market is clearly favoring foundational security and infrastructure layers over legacy applications as artificial intelligence reshapes software business models." The iShares Expanded Tech-Software Sector ETF IGV is down 16% this year.
