Weekend headlines center on China trade strain, tech taxes and Tesla delays

U.S. equity markets were closed for the weekend, leaving QQQ and SPY without a regular-session move. News centered on White House consideration of a China-tariff task force, U.S.-Italy opposition to digital taxes on large technology companies, U.S.-Iran nuclear talks, the IMF's view that global recession was not imminent, a delay to Tesla's lower-cost Model Y, and Japan's resistance to a quick U.S. trade agreement.
