DNA. A very significant bearish trend line

In the chart of DNA (Genentech Inc) we draw a bearish trend line that is very significant.

A bearish trend line is based on lower highs and the significance depends on some factors as the number of times the price touches the line, the angle and the lenght. In this case the price touches five times a four months line with little inclination. Moreover, we have a breakout of a triangular formation and a price/book grater than 8 allowing some "space" for a down move. But in stock markets we deal with uncertainty and for a short position a possible stop loss is some cents above the bearish trend line.
