The biggest component on the Dow as well as the second-biggest gainer on the Dow is Apple Inc. AAPL, which is trading up further in the after-market following a clear earnings and sales beat in the company's fiscal Q3 2017. Apple beat earnings estimates by a dime to $1.67 per share on $45.4 billion in revenues, which beat the Zacks consensus of $44.7 billion.Unit sales were mostly strong; iPhone sales of 41 million in the quarter narrowly missed the 41.1 million anticipated, whereas iPads well-outperformed the 9 million shipments expected by posting 11.4 million. Macs also topped estimates of 4 million units shipped to 4.3 million. Gross margins for Q3 reached 38.5%, the high end of the company's guidance range. Services rose 22% to $7.3 billion, as Other Products (including the Apple Watch) brought in $2.7 billion.Shares are really popping in the late market, now up close to 5%. This follows nearly 30% gains year to date and 44% over the past year. Due to the absence of the new iPhone 8 -- expected to be released later this year -- many analysts expected a lackluster quarter, and Apple outperformed its routinely modest guidance figures. Once the iPhone 8 does hit the market, perhaps in early fiscal Q1 2018, pent-up demand and a high sticker price should further push Apple shares upward. And the stock has now rocketed up to a new all-time high.For more on Apple's earnings results, click here.Cyber-security company FireEye FEYE outperformed analyst estimates on both top and bottom lines this afternoon. This rather volatile firm -- which is up more than 25% year to date but down more than 10% over the past year -- reported a loss of 26 cents per share (accounting for stock-based compensation and other BNRI) on $185.5 million in quarterly sales. These topped the -39 cents per share and $176.3 million expected.Shares ramped up close to 8% immediately following its report, but have tapered off just a bit more recently. Still, a big surge following the record lows hit earlier in 2017. The company is currently a Zacks Rank #3.For more on FireEye's earnings results, click here.Want the latest recommendations from Zacks Investment Research?
