Personally, I dont think the bullish sentiment is due to short covering. It appears to be more timed to the announcement of the signing of the upgraded trade deal (which personally surprises me as the trade deal was done and dusted last November). When short covering does start, that could lead to one almighty short squeeze. Id personally be quite worried if I held a short position in a company, with 60 million other short positions open. Any ounce of good news pushing the share price higher will see any profits on a short position quickly disappear, or potentially mean if they cant close their position in time (buy back shares) they may well end up paying more for them than when they took out the short position (as has happened nearly every other year). Previous years, its been common for A2 to increase several dollars after a trading halt is lifted during the pre open auction, so if guidance comes in within whats been proposed, it may already be too late for Shorters to close out positions. Obviously the same is true of A2 if guidance is missed, the share price has the potential to drop several dollars during the pre market open post a trading halt. From what I have seen and heard, I am leaning towards guidance being achieved, upper end.
