All the major indexes fell more than 1% in trading on Tuesday, and the blue-chip Dow lost as many as 250 points. Crude oil cratered to a six-year low.

First, the scoreboard:

• Dow: 17,402.84, -212.33, (-1.21%)
• S&P 500: 2,084.07, -20.11, (-0.96%)
• Nasdaq: 5,036.79, -65.01, (-1.27%)

And now, the top stories on Tuesday:

1. China's central bank devalued the yuan by 2%. The People's Bank of China set the midpoint of the currency at 6.2298 against the US dollar – a move that sent the USD/CNY currency pair to the highest level in almost three years. Authorities have intervened to bolster a slowing economy and make exports more competitive. Exports fell 8.9% year-over-year in July.
2. Major commodity currencies got slammed. The kiwi and Aussie dollar each extended losses and fell more than 1%. The Canadian dollar climbed to as high as $1.3150 versus the USD. 
3. Crude oil collapsed to a six-year low. West Texas Intermediate crude oil futures fell by up to 5% to as low as $42.70 in New York. The 12-member oil group OPEC reported, citing secondary sources, that its output climbed to a three-year high last month. OPEC has overshot its production targets for at least a year to maintain market share.
4. Analysts love Alphabet. Google shares rallied 5% after the company announced a major re-organization Monday evening: Alphabet will become the parent company of Google and will manage 'non-core' products like Google Ventures. Google will consist of 'core' products like YouTube and Android. Most of the sell-side notes we thumbed through maintained a bullish outlook on the stock. Analysts say the new structure will bring greater transparency to the performance of Google's core products.
5. Apple shares tanked 5% and closed at $113.49. The stock is down 14% since the company released earnings results July 21 that showed disappointing iPhone sales. There were a few downbeat analyst notes published today. Jefferies lowered its price target to $130 from $135 due to Apple's exposure to China, amid the currency devaluation. UBS research showed that there's "lackluster interest as measured by global [internet] search activity" for Apple Watch. And, KGI Securities, known for making accurate product predictions, forecasted flat or negative iPhone sales growth in the fourth quarter.
