There is definitely a dislocation on a few fronts with this stock. There is a rather obvious crowd who use it for day trading, and have done for years, but there is also vital developments taking place that will make the company profitable (and as SAAS likely very profitable). Other than time it has been hard to fault Sigmas developments in the last year, and some important milestones are being hit that will make this company a success.
This dislocation will not last forever and the crowd will disappear faster than you can say boo. They had their fun, but the future is not theirs. With the likelihood of new strategic investors coming in the days of $200 5% moves will become few and far between.
As you wisely point out, study the tech and the market... not the ihub anonymous board
