This chart combines Elliott Wave Theory and Fib Retracement Theory. Sonos is Up 65% YTD and may have a chance to go up 100% on next years chart. Great Speakers. Could end up getting bought out. Their Operating Income and Net income loss has slowly been decreasing over the last 4 years and 2020 may be their first profitable year. I believe that Fair value on this stock is somewhere between $12.5 and $15. Who doesn't love these speakers and speaker systems.
