Big Names Line Up for Busy Week

Costco kicks things off today with its Q4 2026 earnings call at 5pm ET. The warehouse retailer carries a market cap of $401 billion. Short sellers show little conviction — SI sits at just 1.7% of free float.

Tomorrow, Kier Group reports its 2026 full-year results in London. The UK construction firm is a smaller name worth watching for infrastructure sector cues.

Monday brings a trio of releases. Jefferies Financial Group and Vail Resorts both drop Q3 and Q4 results respectively on September 28. IDT Corporation holds its Q4 2026 earnings call the same day.

The biggest event of the week lands Tuesday. Micron Technology reports Q4 2026 results after the close on September 30. The memory chip giant is worth $1.2 trillion. Its SI is low at 2.6% of free float — bulls dominate here. Micron's guidance on AI-driven memory demand will set the tone for the broader chip sector.

Carnival Corporation holds its Q3 2026 earnings call Monday. The cruise operator carries 3.8% SI of free float — modest, but worth watching.

Progress Software and Jabil also report Tuesday. No IPOs are scheduled this week within the next seven days.
