Looking at the chart, Lang noted that in recent days, the price action in Boeing has been quite strong. Not only has the stock gone higher, but it has done so on solid and rising volume.
"This is a classic sign that big institutional buyers are accumulating the stock, and when the big boys get behind something, they have a tremendous amount of firepower to push it higher," said Cramer on Tuesday's broadcast.
Also patterns in the charts suggest Boeing has a strong floor of support at just under $69 - and it's been tested repeatedly. In other words, if the stock declines it shouldn't decline much below $69, according to the analysis.
Second, after Boeing's big rally on Friday, where it vaulted more than $2 in a single session, this stock is now trading above all of its key moving averages.
Boeing has broken out over the 10-day moving average, a short-term measure of its trajectory, it's broken out over the 50-day moving average, a medium-term measure of its trajectory, and most important, with the move on Friday, the stock has broken out over its 200-day moving average, a long-term measure of its trajectory.
All told, the strong technicals – outlined above –are enough to attract buyers.
But that's not all – Cramer said the fundamentals are equally attractive.
