Looks like optimism is sliding downwards...The rate at which this stock price gravitates towards 0.20 seems to be increasing with every bump upwards. Investors seem to think a NR is coming, and it has been a little while since we saw one, so given the amount of action in this sector right now, and the amount of news coming out, Therma:
(a) Has "average" results from testing, or other information and is witholding it (unlikely, since this would bolster the stock price sooner, and Therma wouldn't be a "latecomer" to the rapid Covid testing scene)
(b) Has "average" or "mediocre" testing results, and is strategizing, with Barwicki Investor Relations, on how to release that information without unduly trashing investor confidence in the company. (possible, but they hired Barwicki pretty quick after seeing shitty results if that's the case)
(c) Actually has no new information to announce that would significantly affect stock price
(d) Has "extraordinary" results, and is strategizing information release to somehow maximize future revenue (unlikely based on probability alone)
Those are my thoughts. If I had to guess, they have results, they're similar to those from other companies working on the same thing, and Therma is trying to figure out how to take the biggest piece of pie they can, and will release news once it fits into that "plan".
