It was the shot heard round the galaxy.

Boeing Co. (BA - Get Report) CEO Dennis Muilenburg told CNBC Thursday that his company -- not Elon Musk's SpaceX -- would be the first to send a human to Mars. It wasn't the first time Muilenburg has made that claim. A year ago, he said more or less the same thing at a tech summit in Chicago, according to Ars Technica.

Only this time, Elon Musk caught wind of it.

Musk's reply on Twitter was short and to the point: "Do it."

Now, it seems, people can't stop talking about the intergalactic race between the two companies.

But, for investors, the friendly rivalry between Boeing and SpaceX is a distraction from the upside opportunity here -- Boeing's price action has been stratospheric in 2017, firmly planting the stock at the top of the Dow Jones Industrial Average's best performers list.

And as we head into the final stretch of 2017, Boeing's blastoff trajectory isn't showing any signs of slowing down.

To figure out how to trade it this week, we're turning to the chart for a technical look:

You don't need to be an expert technical trader to figure out what's happening with Boeing right now. Instead, the price rally in this aerospace giant has been about as simple as they get. Since the start of 2017, Boeing's stock has been moving up and to the right in a well-defined uptrending channel.

In short, every test of the bottom of that price channel has provided a low-risk, high-reward opportunity for BA bulls to buy shares. And so, as Boeing comes off the fifth test of trendline support since mid-May, another buying opportunity is presenting itself in Boeing.

That bullish outlook is confirmed by relative strength, the indicator down at the bottom of the Boeing chart, which measures this stock's performance relative to the rest of the S&P 500. Boeing has been outperforming all year long, and it's continuing to make higher lows in its relative strength line. That's an indication that Boeing's outperformance isn't slowing this winter. In fact, shares remain statistically predisposed to keep on outperforming the rest of the market on a three-to-six month time horizon.

If you're looking for an opportunity to buy Boeing here, the latest bounce off of trendline support, confirmed this week, looks like a solid opportunity.

From a risk management standpoint, the 50-day moving average looks like a decent (if wobbly) proxy for trendline support. Consider parking a protective stop on the other side of the 50-day if you decide to pull the trigger on Boeing's uptrend here.

Meanwhile, all systems are go in this aerospace trade.
