All I can tell you is that markets don't go down in a straight line. Look at a chart of the 1929 crash, after 9/11, or the financial crisis. After downdrafts, there were these huge rallies that recouped large portions of the losses. They all eventually turned back lower. After dramatic declines like that, it doesn't take good or even OK data in order to rally...it just takes "less than apocalyptic" information. We've gotten a stream of that kind of information over the last couple weeks. Combine that with the unprecedented Fed stimulus, and you have the recipe for a bounce. If the economy does not begin to slowly re-open sometime in early May, I bet we do turn back lower.
Travel industry stocks are still absolutely decimated and have given up the entirety of their bounce. The banks have bounced, but are still 35% off the February highs. Despite the bounce, the S&P is still down 20% from the high as of this morning. By Scahill's tweet, you're left with the impression that the economy is still awful but the markets have totally recovered, like they are in excess of the old high, and that's isn't the case. I get it - he's trying to make a political point, but he doesn't understand markets.
