Pfizer's Vaccine Show Promise, But Jim Cramer Says To Sell The Stock...Why?

Before the opening market bell on Monday, Pfizer said its coronavirus vaccine shows it is more than 90% effective. Pfizer said that the vaccine, made with German partner BioNTech, had an efficacy rate higher than 90% at seven days after the second dose, which means protection is achieved 28 days after a person begins vaccination.
On the news, the equity markets soared, but Jim Cramer said to sell Pfizer. There is only one reason Jim is saying to sell, lets go to the charts.

MY TRADING METHODOLOGY IN A NUTSHELL BELOW

I’m a supply and demand trader. The premise of supply and demand trading is when the market makes a sharp move up or down the large institutions i.e banks/hedge funds are not able to get their entire trade placed into the market, leaving pending orders to buy or sell at the zone with the expectation the market will return to the zone and the rest of their trading position will be filled.

I use multiple time frame (MTF) analysis to improve my discretionary trading decisions. MTF analysis involves analyzing the same asset on multiple time frames. The rule of thumb when using MFT is you want your charts to scale down/up by 4X – 6X. In my case I tend to look at:

Monthly Charts (curve time frame) – which represents that jet fighter flying over the football stadium.
Weekly Charts (trend time frame) – which represents the concession stands looking down at the field.
Daily Charts (entry time frame) – which represents being on the football field with the player.
4 Hr Charts (entry time frame) – which represents the center hiking the ball to the quarterback.
