Apple (AAPL) says save the date, and Walt Disney (DIS) shares are on the rise, this is what's moving the markets on Wednesday.

Wall Street tumbled Tuesday after the Polish prime minister warned about the possibility of Russia invading Ukraine. Elsewhere, Italy fell back into recession. The Dow Jones Industrial Average fell 140 points, its fourth loss in five days.

Also on Tuesday, two potential mega deals collapsed. 21st Century Fox (FOXA) dropped its bid for Time Warner (TWX), and Sprint (S) is no longer pursuing a merger with T-Mobile US (TMUS).

But investors are bidding up Disney shares in Wednesday morning trade. The entertainment giant’s studio saw enormous returns in the quarter. “Frozen,” “Captain America 2: The Winter Soldier” and “Maleficent” grossed nearly $3 billion worldwide.

And it looks like we have a date! Apple has a big media event reportedly scheduled for Tuesday, Sept. 9. That’s when the tech behemoth is expected to announce the new and bigger iPhone.

Remember, cyber-attacks can happen to your car, too. Chrysler and Nissan are now reviewing a report by a cyber-security team that rates their vehicles among the three most hackable cars on the market. The 2014 Jeep Cherokee and Infiniti Q50, along with General Motors’ (GM) 2015 Cadillac Escalade, were deemed the most hackable. That means they have features such as Wi-Fi and Bluetooth that hackers could gain control of remotely.
