Today's charts: Lululemon shares crash; Toyota recalls 2.9M vehicles; Amazon to shut down struggling sites

Yahoo Finance is tracking Lululemon, Toyota, Amazon and McDonald’s in midday trading on Thursday.

Lululemon (LULU) – Shares of the athletic retailer are sinking after reporting mixed earnings and weak fiscal first-quarter guidance after the bell on Wednesday. Lululemon noted that a slowdown in store traffic and fewer online shoppers is weighing on its business. The stock is on track to suffer its biggest one-day percentage loss since December 2008. Lululemon reported adjusted earnings per share of $1.00 on revenue of $790 million.

Toyota (TM) – The automaker is recalling 2.9 million vehicles globally over problems with Takata airbag inflators. The recall affects vehicles sold in Japan, China and Oceania, but does not involve any vehicles sold in the United States.

Amazon (AMZN) – The retail giant is shutting down Quidsi, the parent company behind Diapers.com and Soap.com, because it’s unprofitable. The closure will result in 263 people losing their jobs. Amazon bought the company for about $545 million in 2011.

McDonald’s (MCD) – The fast-food chain is switching from frozen beef to fresh beef in its Quarter Pounder burgers by mid-2018. McDonald’s announced that the majority of its restaurants nationwide will make the switch as it looks to boost its business and attract more customers.
