Dynavax Technologies Corporation is exhibiting very strong recent price momentum with the stock closing at the top of its 52-week range alongside multiple bullish technical signals and elevated volume. At the same time, the 14-period RSI near 90 and high short interest metrics point to an overextended and potentially volatile near-term backdrop. Fundamentally, the company combines high gross margins and positive free cash flow with ongoing GAAP net losses, while recent news centers on a proposed all-cash acquisition at a modest premium to the current price.
