The Week Ahead

Investors will have many reminders in their corporate calendars this week as we roll on into height of earnings season. About a quarter of S&P 500 companies report in what will be the last big week for second-quarter earnings. Earnings are up about 22.6 percent over last year and are beating estimates at a pace of 4-to-1. Apple, Caterpillar, Procter and Gamble, DowDuPont, Pfizer and Tesla are among the names reporting, but Apple will be the most widely watched. Berkshire Hathaway, Barclays, Tesla, Toyota, BMW, and Rio Tinto are also scheduled to announce their latest numbers.

Trade will be a highlight in the economic calendar on Wednesday when $16 billion in tariffs on Chinese goods are expected to be implemented, and China is expected to put tariffs on U.S. goods in return. Administration officials have said talks with China have basically stalled, which is another reason analysts expect progress with Europe and on revising the North American Free Trade Agreement with Mexico and Canada.

Central banks in the U.S., Japan, the U.K., Brazil and India all meet this week. The Bank of Japan may tweak its yield-curve control policy and cut its CPI forecasts, while the Bank of England is expected to hike even amid Brexit gloom. US The Federal Reserve meets Tuesday and Wednesday, but little is expected from the meeting, and it does not include a press conference.
