I believe this is because the virus hasn't been a huge deal outside of China, plus the Chinese government are pumping their market right now. So you have the Fed pumping the USA market with liquidity (though that is supposed to come offline soon) and the Chinese government pumping money into their market. Hard to fight. Plus I believe the number of new corona cases is starting to slightly go down each day relative to the day before for the last couple days.
I do think all this liquidity injection could end badly, but I have no idea how to call a top in the market. However, the last couple days have had weird price action. Gap higher on open, move sideways the rest of the day. Gap up again at open, move sideways rest of the day. These movements aren't normal and maybe it is a signal of something bigger. Usually you need a blow off top before the market truly peaks, and the 20 year anniversary of the March 2000 dot com crash bubble is coming in a couple weeks.
Though I don't think the USA market is due for a crash. A pullback I could see., more than the 3 percent we had last week (which has already been made up and more).
For me, Tesla's parabolic move this last week is kind of eye opening to how people are really starting to reach to try and make money. Tesla is an abnormal stock in the first place but the movement the last couple weeks is super abnormal even for Tesla. Even with an over 200 point drop from it's high of a couple days ago, at the close today Tesla is being valued as a 135 billion dollar company.
The stock market is definitely not acting normal right now. Yet stocks (and the stock market) can stay irrational for a long time. Despite my skepticism on the current stock market I can't deny that most long term technical indicators are pointing positive. So it isn't like I believe the sky is falling yet. Just noticing a lot of abnormalities lately.
