NEW YORK: Whipsawing bond yields, surging oil prices and a Federal Reserve bent on squashing the worst inflation in four decades are hampering investors' ability to assess U.S. stock valuations, even as the market's tumble creates potential bargains.
Without a doubt, stocks are far cheaper than at the start of the year, following a 23% year-to-date decline in the S&P 500 .SPXthat confirmed a bear market for the index earlier this week.
Whether they are cheap enough, however, is less certain. Market volatility and a rapidly changing macroeconomic landscape have clouded metrics that investors typically use to value stocks, such as corporate earnings and Treasury yields, keeping some potential buyers on the sideline.
"Until we see some better visibility on the rates outlook and some better visibility on the earnings outlook, the fair value for equities is a little bit elusive," said Sameer Samana, senior global market strategist at Wells Fargo Investment Institute. The institute recently started recommending clients reduce equity risk and move funds into fixed income.
Stocks came under more pressure this week, with the S&P 500 falling to its lowest since late 2020, in the wake of the Fed enacting its largest rate-hike in nearly three decades.
This year's decline lowered the index's forward price-to-earnings ratio, which compares its price with its expected profits, to 17.3, from 21.7 at the start of 2022 – closer to the market's historic average of 15.5, according to Refinitiv Datastream.
But while S&P 500 earnings are expected to rise nearly 10% in 2022, according to Refinitiv IBES, some market participants doubt those estimates will hold up in the face of surging inflation and tightening financial conditions.
Wells Fargo institute strategists forecast positive but slowing earnings growth this year and a contraction in 2023, as they expect a recession in late 2022 and early 2023.
"We are advocating to investors to consider an economy and an earnings backdrop that may be more challenging... so just don't be fooled by where valuations are based off of today's expectations," said Chad Morganlander, portfolio manager at Washington Crossing Advisors, who is recommending clients continue to underweight equities.
Morgan Stanley analysts expect earnings to come in between 3-5% below consensus views, leading them to forecast that the S&P 500 is likely to see a "more reliable level of support" at 3,400, some 8% below Friday's level, they wrote earlier this week.
U.S. Treasury yields also play an important role in standard valuation models. Since U.S. debt is seen as a relatively risk-free investment, rising yields tend to dull the allure of stocks, as they weaken the value of future cash flows in standard models.
