30% is *good*
It's all relative, if your competitor collapsed by 50% and you collapse by 30%, you're a winner! That drop is everywhere, even in places that did a successful COVID 19 quarantine, so I wouldn't worry about the absolute numbers, its the relative numbers that matter. I'm seeing drops tight across ASEAN and it doesn't bother me. The same companies that rank highly still rank highly, its just that they had a revenue drop.
US Federal Reserves intervention, last number I heard for it was $5.1 trillion, and ontop of the $2 trillion+ US Gov bailout, you're looking at 35% of US GDP as worthless junk. So you're 5% ahead already of US so far.
UK, well sure you've had Covid round 1, but there's just no need to have round 2 of Covid19. USA is expected to get hit with another round (courtesy of Trump), so there's a chance to get ahead of them.
Assume US gets a second hit, ~50% damage. Assume Republicans block elections undermining democracy, ~60% damage, assume Trump makes a grab for absolute power in January ~90% damage.
Meanwhile UK tightens is quarantine (particularly the face masks rules), joins Germany and the rest of the world and moves on from Covid19. I'm not a China fan, but the new world order seems to be inevitable. World trade priced in Euros and Yuan, not ideal for the Pound, but if you handle it strongly the the pound would be strong.
BTW, Trump has banned the CDC from releasing their guidance on opening businesses safety, he's been ignored, he'll probably do a meltdown on twitter this weekend, or get his butler to invade Cuba or something ridiculous, but it makes a lot of sensible points. For what its worth, yanks, try to save yourselves:
