Wall St. is betting on earnings growth in the second half of 2016

Will earnings growth return?

That’s the most important question in the stock market (^GSPC) right now. After all, in the long-run stocks are fundamentally driven by earnings and expectations for earnings growth.

Currently, analysts estimate that S&P 500 earnings fell by 5.3% year-over-year in Q2, marking five consecutive quarters of earnings declines since the financial crisis. While this is a dismal trend, it’s backward-looking. Investors and traders want to know what’s going to happen next. What happens next is what will move stock prices.

“Earnings estimates and revision momentum have been improving in recent weeks, as the bottom in commodity prices in Q1 appears to be offering some much needed support to the earnings stream,” Wells Fargo’s Gina Martin Adams observed on Tuesday. Along with the rest of the consensus, Adams expects earnings growth to pick up in the second half of the year.

Earnings growth is critical when valuations are this stretched

Stock market bears are quick to point to stretched valuations in the stock market. According to FactSet, the forward 12-month price/earnings ratio is 16.4, which is well above the 5-year average of 14.6 and the 10-year average of 14.3.

However, stock market guru Richard Bernstein recently argued that we are entering an earnings-driven bull market, in which stock prices can continue to rally while P/Es contract because earnings growth picks up.

Importantly, earnings growth acceleration is expected following long periods of lackluster earnings, like that which we have been experiencing.

“Earnings-driven bull markets seem to be the norm during the year following a profits recession trough,” Bernstein observed. “Typically, the market advances about 13-15% and multiples contract about 1-2 multiple points.”

But the path to earnings growth isn’t clear

As earnings season kicks off next week, investors and analysts will be reading earnings releases and listening to conference calls for clues as to what management expects to happen next.

“We will be watching closely to see if expectations for a near term trough stick or are pushed out, as has been the case over the last few quarters,” Credit Suisse’s Lori Calvasina said on Wednesday. “We continue to believe that any second half 2016/early 2017 recovery in EPS growth hinges on the outlook for global IP and the US Dollar, as using our calculation, EPS growth has been positively correlated with global IP momentum and inversely correlated with the US Dollar in small, mid and large cap over time.”
