Over the past few weeks we've mentioned several stocks that have tested the support of a long-term trendline. As you can see from the chart below, today's chart is no different. We've chosen to look at Boeing because it has a stock price near an influential long-term trendline. As you can see from the chart below, the ascending 3.5 year trendline has propped up the price numerous times in the past and it will be interesting to see if the price will bounce off of it once again. We'd expect to see the long-term trend continue upward until the bears send the price below the support, which is currently at $75.
