Technical Summary: The HSO chart over a 5 year period looks pretty disappointing for long term holders with the stock trading lower than where it was in 2013. This downward trend continued through 2017, culminating in a massive selling gap in August 2017. From this bottom the stock has started to behave more constructively with the stock making a higher low. Currently the stock has pulled back within this new trend. It could go either way from here, maybe the stock forms a new higher low and would therefore be buyable on strength. The other way this can be intrepreted is a resumption of the down trend.
