Buy the rumors sell the news. Real life example AUSSI VS LOONIE

After last week's elections, relatively strong domestic data and perceptions of stable (or even stimulating) fiscal policies were sufficient to keep the doves in the bay for BOC and I assume loonie was performing well throughout months because this thing was already known by smart players. Most of the position was well placed in the loonie side for months by smart traders and was a "buy the rumors" case for market (hoping for steady monetary policy from the bank and rumors around buying in optimistic of BOC) and now when the actual date central bank had announced which also ended up being steady, no cut, no dovish and as expected! but market just turned opposite for the pair or we can say any pairs which have loonie as counter or base acted just opposite against the loonie and ended up being "sell the news" (even knowing it was steady release, no cut, no dovish now everything has already been priced in, juice sucked up so profit-booking by closing of position creating back new fresh demand in another side and doesn't matter what was released and what only matter was to sell on news). Priced reached in such a level where everyone fears to hold longer and where smart people thought good place to book the profit which creating good demand and is indeed in a demand level where nothing can stop from rising upward rather than falling back deep. Aussie has been doing well lately along with the EURUSD and GBPUSD and has a high potential for trending upward talking about the longer time horizon (which we can evaluate from AUDUSD performance). Oil future seems not well too and if loonie is really done, for now, juice has been sucked up months before then a pullback of this downtrend is what not a surprising thing which we may see in future days.
