Warren Buffett’s company, Berkshire Hathaway (BRK-A) has done a couple of rare things over the past year. One of them is under perform the broad markets and the other is, it looks to have formed a bearish “descending triangle pattern” over the past 14-months. See the “descending triangle pattern” definition below from Fore-Tribe.com

The main components of this pattern are; horizontal support and a series of lower highs.  Below is a look at Berkshire Hathaway over the past 20-years and the potential it has been forming a descending triangle over the past 14-months.

Berkshire Hathaway has been a stellar performer over the past twenty years, outperforming the broad market by a large percentage. As mentioned above, BRK-A remains inside of a 20-year rising channel. For one of the first times in a long, long time, BRK-A has under performed the broad markets over the past 14-months. This under performance took place, after the stock hit rising channel resistance in January of 2104.

Since hitting channel resistance (A), the stock has made a series of lower highs and a series of flat bottoms, forming what looks like a bearish descending triangle. Should BRK-A break overhead falling resistance, it would be good for the stock and it should run higher to test channel resistance again.

What to watch for, with a bearish descending triangle in play. Support at the 19,000 level becomes very important for the stock. Should the support line be taken out, the “measure move” would then suggest sellers drive the stock to the 16,000 level.

In the late 1990’s and in 2007, the stock created a series of lower highs and once support broke, sellers took control. As mentioned above, support is still in play and will remain until broken. BRK-A shareholders want support at the 19,000 level to hold and overhead resistance is taken out, so that this descending triangle pattern, doesn’t come true.
