Then important role of Technical Analysis
Alexander Elder:

The key principle is to use fundamental information as an idea generator and technical studies as a trigger. The technical can either release you to pursue that trade or stop you from going any further.
No matter how good a fundamental story, if the technical factors do not confirm it, there is no trade. This rule applies to both bullish and bearish fundamental information. When the fundamentals suggest a trade and technical factors confirm that signal, you have a very powerful combination.

Unfortunately, for both the general market and AMRN, both fundamentals and technicals aver been in bearish sync to the downside, hence the falling knife.
