A surprising surge in U.S. retail spending in September helped push the Dow Jones Industrial Average (DJINDICES:^DJI) higher on Friday. Total retail sales rose 1.9% in September compared to August, well ahead of the 0.8% gain expected by economists. The strongest categories included clothing, sporting goods, and motor vehicles. The Dow was up about 0.8% at 1:20 p.m. EDT.

Rising along with the Dow were Walmart (NYSE:WMT) and Boeing (NYSE:BA) stocks. Walmart got a boost from an analyst "buy" rating, and shares of Boeing surged after Europe's top aviation safety regulator called the 737 MAX safe to fly.

Analyst optimism for Walmart

Walmart's investments in various e-commerce initiatives, including free two-day shipping and online grocery shopping, paid off big time during the pandemic. The company experienced robust sales growth in the second quarter, with U.S. comparable sales up 9.3% and U.S. e-commerce sales soaring 97%.

Jefferies analyst Stephanie Wissink sees these trends continuing to drive Walmart's results. Jefferies rated Walmart stock a "buy" on Friday and attached a base case price target of $165, with a bull case price target of $180. Wissink expects Walmart to increase its share of consumer spending through its omni-channel initiatives, partnerships, and services.

On the services front, Walmart launched its Walmart+ membership program last month. For $98 annually or $12.95 monthly, members receive unlimited same-day delivery of groceries and select general merchandise. With consumers turning to grocery pickup and delivery services during the pandemic, Walmart+ could be a big winner for the retailer.

One wrinkle in this optimism is the impact of economic stimulus on Walmart's results. The $2.2 trillion CARES Act sent checks to Americans and boosted unemployment benefits for months, driving consumer spending during the worst of the pandemic. Walmart's sales growth began to slow after those benefits lapsed, so the retailer will likely see more modest results absent a new stimulus bill.

Shares of Walmart were up 0.5% by early Friday afternoon. The stock has gained about 22% so far this year.

Boeing's 737 MAX deemed safe in Europe

It's been a long road for Boeing's 737 MAX since the plane was grounded following two fatal crashes related to faulty flight-control systems. Getting the plane back in the air requires approval of Boeing's changes by regulators around the world, a process that has dragged on.

A significant milestone was reached on Friday with European Union Aviation Safety Agency Executive Director Patrick Ky saying in an interview that the 737 MAX has been deemed safe following test flights in September. EASA is expected to issue a draft airworthiness directive sometime next month, according to Ky.

Ky sees the 737 MAX flying again in Europe before the end of 2020, despite a fix EASA is requiring not expected to be in place anytime soon. Development of a synthetic sensor for the 737 MAX, a software solution that will add redundancy, will take as long as two years. The solution will be required on the 737 MAX 10 prior to its expected 2022 launch, and it will be retrofitted onto other versions of the plane.

Shares of Boeing got a boost from the 737 MAX news, up about 2.6% by early Friday afternoon. The stock has been hammered this year, down around 48% year to date.
