The end of the magic stock market

The stock market's magnificent bounce in 2019 has been hard to explain and fueled largely by factors like stock buybacks and central bank easing.

The big picture: But to see an increase in their share prices next year, U.S. companies will have to actually increase their earnings, experts say, a factor that's been notably absent from this year's rally.

By the numbers: As of Tuesday's close, the S&P 500 has risen 25% while U.S. corporate earnings growth has been negligible. Data from FactSet shows the S&P's earnings will likely be negative in every quarter this year — the first time it has fallen in four straight quarters since 2015–2016.

• To be sure: Companies have seen earnings growth this year, but that has been almost entirely due to stock buybacks, Jill Carey Hall, U.S. equity strategist at BAML, tells Axios. "Pretty much all of it."

State of play: U.S. economic growth also has slowed, as businesses have cut back on investment and capital expenditures, and started boosting their cash holdings.

• The market hasn't been fueled by a rush of irrational exuberance either. Traders have been net sellers of stocks in every month this year, pulling a record $130 billion from equity mutual funds and ETFs through the end of October, data shows.

What happened: 2019 was all about the rise in multiples, as the S&P 500's price-to-earnings ratio rose over the course of the year.

• "The Fed was a big contributor" to that theme, Hall says, having cut already low U.S. overnight interest rates three times this year and added nearly $300 billion of bonds to its balance sheet.

What's next: In 2020, analysts expect the Fed to remain on the sidelines through the year and for multiple expansion to cool.

• Gains in the stock market will come largely from U.S. economic growth and earnings, which fund managers at BlackRock see growing at 8%, combined with an average dividend yield that rivals the U.S. 10-year Treasury note and continued share buybacks from companies.
• There are no expectations for a meaningful trade war resolution, just a ceasefire that allows the U.S. to grow "around trend," or close to 2% for the year.

The bottom line: "The handoff for growth that we see in 2020 is a meaningfully less powerful driver than multiples were in 2019, which is why the expectations for this coming year are more muted than we’ve seen in 2019," BlackRock's global chief investment strategist Mike Pyle tells Axios.

Go deeper:

• The market will need the Fed again in 2020
• A record amount of money has been pulled out of stocks in 2019
• Traders keep selling stocks and stuffing cash into savings accounts
