Key principle of trend theory is that trends don't change direction unless there is a 'shock' to cause a reversal
So AIR have to come up with something exciting to break this current downtrend. Until this (good news) happens expect the current trend to continue.
The long up trend was going fine until that infamous Investor Day Briefing last May - that was the 'shock' that caused that uptrend to reverse and started this current downtrend.
