9 am: Energy dividends attractive, but be careful

Energy dividends are very attractive, but the old buyer-beware is still very alive. With the energy sector at a 10-year low, dividends on many energy stocks are well outpacing boring old utilities:

But many companies may again have trouble paying those dividends out from cash flow and may have to borrow to keep shareholders happy. Barron’s notes that Chevron needs a Brent price of $57 a barrel and ConocoPhillips, $55 a barrel. Exxon Mobil needs a much higher oil price of $87 a barrel to cover its 2020 dividend from earnings, Barron’s says, citing a JPMorgan report. —Pisani

Goldman Sachs downgraded its earnings growth forecast for the year to $165 per share, representing 0% growth in 2020 for U.S. companies.

The Dow and S&P 500 were set to open in correction territory — down at least 10% from their 52-week highs — as coronavirus fears rattle market sentiment.

A loss of that magnitude would put the broad index below 3,047.53. —Imbert, Schacknow

7:25 am: 10-year Treasury yield hits fresh record low

The 10-year U.S. Treasury note yield broke below 1.3% for the first time ever as concerns over the coronavirus spreading in the U.S. led investors to dump equities in favor of traditionally safer assets.
