US equity investors will remain focused on the Trump administration's trade tariff announcements this week while watching quarterly earnings, corporate guidance, and retail sales.

* "President Donald Trump's tariff policy just took a sharp turn -- again," SAXO said in a research note Monday. The White House excluded major electronics categories from the steepest round of tariffs after imposing a 145% levy on Chinese goods and 10% on imports from other trade partners.

* "This move signals a shift from country-specific reciprocal tariff strategy to sector-focused protectionism," Saxo Chief Investment Strategist Charu Chanana said in the note. "While the 20% China tariff remains in place -- especially targeting fentanyl-related imports -- the US appears to be laying the groundwork for new semiconductor-focused tariffs under Section 232, a national security clause that could make these duties more durable and harder to reverse."

* Apple (AAPL) shares jumped 4.9% in premarket activity on Monday. It was up 5.2% last week, underperforming all its peers in the Magnificent-7 group. The company was hit by Trump's tariffs, given its heavy reliance on China for manufacturing.

* Meanwhile, following the release of the retail sales data for March on Wednesday, Federal Reserve Chair Jerome Powell will deliver a speech. Other heavyweight fed speakers on the tap this week include Fed Board Member Christopher Waller, Richmond Fed President Thomas Barkin, and San Francisco Fed President Mary Daly.

* Mega-cap earnings due include Goldman Sachs (GS), Bank of America (BAC), Citigroup (C), Netflix (NFLX), Taiwan Semiconductor Manufacturing Company (TSM), and UnitedHealth Group (UNH). "Of the less than thirty S&P500 firms that have released thus far, about three-quarters have been consensus EPS expectations and just over half have beaten on revenues," Scotiabank said in a research note late Friday.
