No doubt about it, 2017 has been a blockbuster year for shares of $108 billion graphics-chip giant Nvidia Corp. (NVDA - Get Report) . Shares are already up nearly 70% since the calendar flipped to January, capping off a monumental rally over the last few years.

Now, understandably, many investors are starting to think that we could be in the final innings of Nvidia's upside -- how much further could shares possibly go, after all?

A lot further.

Nvidia has substantial tailwinds pushing shares higher right now. Cryptocurrency mining and next-generation video games are two obvious ones that have been fueling growth for Nvidia's GPUs over the past several quarters. But the biggest is undoubtedly artificial intelligence. As more applications of artificial intelligence and machine learning reach production stage, the need for high-performance GPUs to train and run models will continue to increase.

For instance, GPU acceleration with the popular TensorFlow deep learning software library currently requires Nvidia GPUs, prompting most of the cloud service providers to buy up scores of machines with Nvidia hardware in them.

We're still very much in the early innings of that new tech. And that leaves a lot of open runway for Nvidia to continue revving up price momentum in the quarters ahead.

That's certainly showing itself to be true in the price action. Nvidia's bullish price trend is alive and well this fall -- and shares are teetering on the verge of yet another breakout as I write. To figure out how to trade shares, we're turning to the charts for a closer look.

You don't need to be a trading expert to figure out the overarching trend in Nvidia's price chart this year -- buyers have been in control, and Nvidia's stock price has been moving up and to the right. Shares hit their head on resistance up at $190 in the middle of September, but the nearer-term uptrending support line that connects the lows since July has been squeezing shares closer to a breakout above that prior price high.

In short, Nvidia is on a collision course with a breakout through the $190 level. And that breakout could come with even bigger upside implications considering the psychological effects of nearing a round-number like $200.

Relative strength confirms the bullish price action in Nvidia right now. Our relative strength line is in an uptrend of its own, signaling that Nvidia continues to outperform the rest of the broad market this fall, even after its strong upside year to date. If you're looking for a buying opportunity in this tech giant, wait for shares to crack $190 before you pull the trigger on the trade.
