For investors trying to work out if the <a href="https://www.thenationalnews.com/business/markets/2022/08/13/global-stock-markets-rise-amid-optimism-over-us-inflation-slowdown/" target="_blank">stock market rebound</a> has staying power, Apple holds a clue. The world’s most valuable company has the biggest influence in the S&P 500 Index and its participation in the market capitalisation weighted benchmark is essential to any sustainable rally. Apple shares beat the S&P for a ninth consecutive week and have helped to fuel a 22 per cent rebound in the tech-heavy Nasdaq 100 from a low in June. Apple is a so-called tent-pole stock that dominates investor attention and can help define investment narratives, according to Nicholas Colas, co-founder of research firm DataTrek. In that respect, he said, Apple’s recent performance is “quite heartening”. The S&P 500 is down 10 per cent in 2022 despite rallying since June. Apple’s shares, on the other hand, are on the cusp of turning positive for the year after tumbling with other technology stocks in the first half. Its shares have outperformed in both of the bull markets since the 2008 financial crisis. In snapping up Apple shares, investors are betting that the iPhone maker’s strong balance sheet will allow it to continue returning cash to shareholders and wring big profits out of its more than 1 billion users despite the potential for a recession in the US with the Federal Reserve bent on fighting soaring inflation. “Apple is a safe haven that people flock to when uncertainty abounds in the rest of the market,” said Daniel Morgan, senior portfolio manager at Synovus Trust. “Apple shares are driving the rally in the S&P 500 based on the durability of its model.” Like the broader market, risks to Apple’s ascent abound. Inflation is weighing on consumers while China’s stringent Covid-19 policies pose a lingering threat to its supply chains. While Apple has reportedly asked suppliers to maintain last year’s pace of iPhone production, some of them are sounding alarms over a pullback in demand. Micron Technology this week said that sales in the current quarter are expected to be weaker than it anticipated six weeks ago, when the maker of memory chips gave its forecast. That followed disappointing revenue projections from Qualcomm, Intel and Nvidia. The sobering news from chipmakers, however, did not stop technology stocks from rallying this week after a US consumer price gauge came in lower than expected, a result widely interpreted as easing pressure on the Fed to continue interest rate rises to tame inflation. The Nasdaq 100 advanced 2.7 per cent, with more interest rate sensitive stocks like cyber security company Zscaler jumping more than 10 per cent. For Apple, the rising stock price has put the shares back in expensive territory. It’s now priced at 27 times profits projected over the next 12 months, compared with an average of 17 over the past decade. That is making investors like David Bahnsen, chief investment officer at the Bahnsen Group, wary of buying the stock at current levels. “Apple is probably the safest of the FAANG plays, but it isn’t an attractive entry point,” he said, referring to the cohort of mega-cap technology companies that includes Facebook, Apple, Amazon, Netflix and Google.
