Judging by the number of times that Twitter (TWTR) tried to hold a rally into new highs above 30.00 and failed since its IPO in 2013, I'd have to say that that is precisely where its fair value lies, as shown on the following monthly chart.
By the way, Twitter's performance has been so poor over the years that it was dropped from the FNGU ETN basket of stocks and replaced with MSFT, as noted in my post of February 2.
