After the closing bell yesterday, NVIDIA NVDA) disappointed investors with its second-quarter fiscal 2019 results. Though the biggest maker of graphics processors beat the Zacks Consensus Estimate for both the top and the bottom lines, it provided bleak revenue guidance for the ongoing quarter, citing sudden decline in cryptocurrency-mining sales.Shares of NVDA dropped as much as 6.4% in aftermarket hours.Q2 Earnings in DetailEarnings per share came in at $1.94, crushing the Zacks Consensus Estimate by a dime and improving 92% from the year-ago quarter. Revenues climbed 40% year over year to $3.12 billion and edged past the estimate of $3.11 billion. The performance was powered by a boom in the datacenter and gaming business lines.Datacenter revenues jumped 83% to $760 million, while gaming sales climbed 52% to $1.8 billion. Notably, gaming remains the company's biggest moneymaker and the largest segment, accounting for about 58% of total revenues.For the third quarter of fiscal 2019, NVIDIA expects revenues of approximately $3.25 billion (+/-2%). This is much lower than the Zacks Consensus Estimate of $3.37 billion. The company warned that the extra boost in revenues from selling its graphics chips to cryptocurrency miners appears to be over at least for now. This is because the chipmaker previously projected cryptocurrency-specific products to contribute around $100 million in revenue during the fiscal second-quarter, but these products raked in revenues of just $18 million due to greater-than-expected drop in demand for chips used by cryptocurrency miners. As a result, the company now projects no contributions from cryptocurrency going forward (read: Bitcoin Falls After SEC Postpones ETF Decision).However, data center and gaming business will continue to grow as both the data center graphics processing unit market and gaming GPU market expands. Currently, NVIDIA has a Zacks Rank #3 (Hold) and a Growth Score of A. Additionally, it falls in a top-ranked Zacks Industry (top 14%), suggesting that a dip could be a solid buying opportunity.ETFs in FocusGiven this, investors seeking to bet with lower risk could invest in ETFs that have a higher allocation to this graphics chipmaker.
