Have been hoping such a thread popped up for the last 18 months or so. The armchair CEOs (me included ) could start putting their money where their mouth was.
Going into the Brexit vote I was thinking £4.20 was the top-end of buy territory (price was nearer £4.90 if I recall). My view was there was already downside looking 6 - 24 months out ... not fully offset by the removal of the F tasting menu
Now, three trading days on, there's a significant re-evaluation to get our heads around. I'm thinking through: Is present IAG management geared up to react suitably? What are the revenue upsides here (easy to focus on various downsides)? What in terms of permanent downside to the biz are the markets worried about (and do we/I concur)?

Certainly an interesting topic. Me ... I'll sit it out for a few days.
Fortunately, I sold out a while back at over £6.
