S&P Fake jump yesterday, best time to sell & sell short

Vaccine yesterday not now:

The market didn’t seem unduly upset by comments from U.S. President Donald Trump that he was taking hydroxychloroquine, an anti-malaria drug whose benefits he has repeatedly touted, as a preventive measure against Covid-19. There is no peer-reviewed medical evidence to suggest the drug is effective in preventing the vaccine, while the FDA has warned that it may increase the risk of death through heart disease.
