$SPK spk has seen a slight increase in short positions within the last hour; be mindful of the risk of a pullback. Currently, the short position volume is minimal, and the main force's selling is not evident. Shorting still seems to be at a peak; it's advisable to wait for a pullback before observing for long positions. For shorting, wait until the main force shows a clear and significant amount of selling in the first round, then a volume-less rebound to short at previous high losses is relatively safer.
