Optimism about company earnings has driven share prices higher in the past year. But financial markets are relentlessly forward-looking. And with bumper earnings already in the bag, they now have less to look forward to. A rally in bond prices since March and a sell-off in some cyclical stocks point to concerns about slower GDP growth. A plausible case can be made that the earnings outlook might worsen as quickly as it improved.
Profits swing around a lot. For big businesses, a lot of costs are either fixed or do not vary much with production. Firms could in principle fire workers in a recession and hire them back in a boom so that costs go up and down with revenues. But this is not a great way to run a business. A consequence of a mostly stable cost base is that, when sales rise or fall, profits rise and fall by a lot more. This “operating leverage” is especially powerful for companies in cyclical businesses, such as oil, mining and heavy industry. Indeed, changes in earnings forecasts are largely driven by cyclical stocks.
Slower economic growth is one part of a classic profit squeeze. The other is rising costs. [Over the recent past], A variety of bottlenecks has pushed up the prices of key inputs, such as semiconductors. Too much is made of this, says Robert Buckland of Citigroup, a bank. Input prices typically go up a lot in the early stages of a global recovery. Big listed companies usually absorb them without much damage to profits. Rapid sales growth trumps the input-cost effect. The real swing factor is wages, which are the bulk of firms’ costs.
An obvious remedy for rising costs would be to raise prices. Though inflation is surging in America, that reflects price rises for a small number of items. Many businesses tend not to raise prices straight away. They are mindful of losing customers to rivals who don’t raise prices. And there are administrative costs to changing prices frequently. A study published in 2008 by Emi Nakamura and Jon Steinsson, two academics, found that the median duration of prices is between eight and 11 months. Prices of food and petrol change monthly but those of a lot of services only change once a year.
