Analyst Says Earnings and Interest Rates Remain Key Market Drivers
Tim Holland, chief investment officer at Orion, said the biggest lesson from the first half was that “Earnings matter more than just about anything, except for maybe interest rates,” as quoted by CNBC.
The second quarter proved especially positive for investors as concerns about the AI trade eased and the conflict appeared to move closer to a resolution.
Holland said that if hostilities between the United States and Iran do not increase, he expects the bull market to broaden during the remainder of the year, as per the report.
He explained that “The world continues to focus on the AI capex build out and AI trade, and I think rightly so, but if you look under the hood of the market, what’s been working year to date, and at least for the month of June as well is value stocks as opposed to growth stocks,” adding, “Interest rates are probably going to be a little elevated, which tends to be a headwind for higher price growth stocks, but tends to be a tailwind for economically sensitive stocks and the like,” as quoted by CNBC.
