The Mule is back!!!
This is definitely an excellent thing that Germany is testing a LOT. I agree that with massive testing capacity, it would not be required to rely on lockdowns - in fact, it's the only way we'll be able to exit this crisis. Keep shorting the market until there is evidence that we're actually trying to establish a good testing infrastructure (might want to wait until just before the stimulus bill finally passes, obviously that is a nice pretty object the market will enjoy).
And it's an excellent datapoint to show true mortality rate.
However, your claim about the 0.5% mortality rate is just wrong. You realize the number is going the wrong way, right? A few days ago, the mortality rate in Germany was 0.3%. This is 100% expected, of course. It's just that deaths lag cases, so in the presence of an exponential ramp, you'll always see an artificially low mortality rate. You have to wait for the curve to level off a bit, and then wait about 1-2 weeks.
It looks like Germany has started to bend their curve significantly, so check back on their mortality rate in about 2 weeks (assuming they actually flatten the curve in the next couple days). It'll be about 1%.
For example - look at March 24th's deaths of 159. That can be aligned roughly (it is just approximate) with March 18th's 12k cases. That's 1.3%.
