AMGN  bounces off of N Band Support and Resistance lines routinely, as seen in the circles on this chart.

These hidden price levels are identified by MetaSwing's N Band implied volatility measurement extremes.

Traditional TA methods do not reveal these hidden volatility price levels.  The smart money on Wall Street sees them in advance.

                 Do you?

This support level of 39.51 carries forward to provide a technical stopping point for AMGN's high volatility decline.  A short term reversal is then staged.
On January 3rd the lower N Band establishes a new projected implied volatility support level at 39.51.
