Apple Kicks Off Critical Holiday Season With Watch That Monitors Blood Oxygen

Apple shares have soared this year even as the virus has crippled economies around the world, thanks in large part to booming sales of work-from-home items.

Apple shares were up 2% on Tuesday after climbing more than 50% for the year, well ahead of the 23% gain for the Nasdaq. Even though Apple stock has fallen from a record high earlier this month, it remains near its $2 trillion stock market valuation.

How the new products sell during the holiday shopping season in many markets will largely define how well Apple performs for its entire fiscal year, which started this month.
