Earnings are very much front and centre on Tuesday, particularly with markets mostly treading water as a huge week of event risk gets underway. Five of the megacap tech stocks dubbed the “Magnificent 7” – responsible for powering Wall Street to record peaks this year – report financial results over the next three days, starting later today with Google parent Alphabet. AI poster child Nvidia, which has been vying with Apple for the mantle of most valuable company in recent days, doesn’t report results until much later in November.
