This sentence is one of the best Weasel words I ever see. It is used to trick the listener to derive their own conclusion than provide any solid meaning.
I doubt you will find explicit definition for "technical dynamic", as weasel words, it is meant to create framing effect, many people will fall into the trap and related the technical with Technical analysis. While relating dynamics to positive movements (which is a wrong perception).
Following a perfect storm of negative technical dynamics, recent
spinoff SnakeOil is a coiled spring ready to double over the next year.
Break down the sentence, you will find a verb follows a metaphorical noun, but none of them gives you an affirmative conclusion. E.g. there is no such things as "negative dynamic"; while "the next year" doesn't mean the next whole year, but can be forever.
