This is jargon related to the stock market. Tape is a reference to the old-fashioned ticker tape. "Short-term tape is damaged" means the stock has recently fallen in price, and perhaps that it is going to fall further. The remainder of the passage is meant to reassure the reader that in the longer term the outlook for this stock's price is good.
The passage as a whole is the sort of giddy jabber that comprises almost all news reporting on the stock market in North America.
