US stocks are drawing buyers after a recent tumble, but some investors believe <a href="https://www.thenationalnews.com/business/money/2022/02/22/russia-ukraine-crisis-how-worried-should-investors-be/" target="_blank">buying the dip</a> this time may be a far riskier bet than in the past as markets face geopolitical strife and a <a href="https://www.thenationalnews.com/business/money/2022/01/19/why-the-feds-hawkish-tilt-will-drive-market-volatility/" target="_blank">hawkish Federal Reserve</a>. The benchmark S&P 500 has surged more than 6 per cent from Thursday's lows to close higher on the week, after investors swooped in following sharp declines on the heels of Russia's attacks on Ukraine. On the surface, the swift rebound resembled past bounces the index has experienced in its more than 200 per cent run over the past decade, when "buying the dip" proved a winning strategy. The S&P is down 8 per cent year-to-date and confirmed it was in a correction by falling more than 10 per cent from its record high earlier this week — its biggest decline since stocks lost nearly a third of their value in the Covid-19 selloff of March 2020 before doubling from their lows. Yet while bargain hunters over the last two years could count on the Fed's historically loose monetary policy to offer stocks support, today they face heightened geopolitical uncertainty and a central bank that is expected to pull out the stops in its fight against inflation — starting with a widely anticipated rate increase in March. "Investors were trained to buy the dip because they had the backing of the Fed. But now you could make a case that this is one of the most significant geopolitical events for the last decade, and you don't have the Fed in your corner," said Burns McKinney, a senior portfolio manager at NFJ Investment Group. Anticipation of Fed tightening has weighed on markets in recent weeks, as investors price in around 165 points of interest rate increases by next February. Fed chairman Jerome Powell said he expected to raise interest rates in March for the first time since 2018. Others expect geopolitical tensions to continue plaguing markets as the implications from the war in Ukraine become clearer. Kyle Bass, founder and chief investment officer of hedge fund Hayman Capital Management, believes investors still have not factored in all of the possible outcomes that could result from Russia's invasion of Ukraine, including a prolonged conflict that weighs on global growth and sends inflation higher by pushing up commodity prices. "This is going to get worse before it gets better," he said. "Asset managers don't have these outcomes in their realm of possibilities." Investors should own assets that can hold value during inflationary times, such as commodities and real estate, Mr Bass said. Mr McKinney is buying dividend-paying stocks that he expects to withstand future volatility in the market and moving some money into defense companies. In addition to the fast-moving situation in Ukraine, investors next week will be watching Friday's non-farm payrolls data for February — the last such employment report the Fed will see before its monetary policy meeting in March. Though Ukraine remains in flux, those in favour of buying on weakness argue that stock declines from past geopolitical events have been short-lived. LPL Financial's study of 37 major geopolitical events since the Second World War found that stocks were up an average of 11 per cent one year later, provided a recession does not occur. Retail investors have been among the dip buyers, purchasing a net $1.5 billion on Thursday, data from Vanda Research showed. BlackRock earlier this week added to its strategic overweight in equities, saying investors may be overestimating how hawkish central banks will need to be in their battle against inflation. JPMorgan's analysts, meanwhile, argued that "initial volatility around rate lift-off didn't last and equities made new all-time highs two to four quarters out". Others, however, are taking a more dour view, as the markets price in Fed tightening in the face of soaring inflation. "We're bearish," analysts at Bank of America Global Research wrote in a recent note, saying they believe the "bull era of central bank excess, Wall St inflation, [and] globalisation" is ending, to be replaced by a "bear era" of inflation and geopolitical isolationism. Charles Lemonides, portfolio manager of hedge fund ValueWorks, has been increasing his bets against some stocks, including semiconductor maker Broadcom and plant-based meat company Beyond Meat, sceptical that markets will be able to sustain a rally in the face of a hawkish Fed. "The reality is that the market has had a huge run and inevitably you give back some of those gains," he said.
