Investing legend Jeremy Grantham flagged a huge market bubble and predicted an epic crash. Here are his 12 gloomiest warnings since the pandemic began.

In a series of outlooks and interviews between the spring of 2020 and the end of 2022, Jeremy Grantham warned investors that they were in danger of being caught in a historic bubble.

The last three market bubbles were called by the market historian for the company. He pointed to investor euphoria, excessive valuations, and rampant speculation on risky assets as signs of doom.

Here are Grantham's 12 best quotes since the pandemic began, lightly edited and condensed for clarity:

This is the first thing. This is the fourth real McCoy bubble of my investment career, and I'm growing more confident by the day. June 2020 is a new year.

There are two A bubble is when the market can go up on bad news and go down on good news. There isn't much you can do when it starts. The year 2020 begins in November.

There are three. I don't think I can time the bubble breaking. I don't have a good definition of success, it's that the market will be lower than the point at which I suggested you should leave. The year 2020 begins in November.

There are four. This could be the most important event of your investing life for the majority of investors. We are waiting for the last dance and finally for the music to stop. January 2020

There are five. The bubble has always been broken in the next few months when you reach this level of enthusiasm. January 2020

There are six. I have no doubt that this one will end badly, even though I sympathize with these people who are enjoying this bubble. February 2020

There are seven. With the biggest loss of perceived value from assets that we have ever seen, we will have to live. May 2020

There are eight. People will lose everything in the end. I'm sorry for them because I'm sure they can't afford it. May 2020

There are nine. Knowing when the bust will come is more difficult than seeing bubbles. When the news is full of stories of people getting cheated, when new coins are being created every month, and when the markets are on the front pages, you can see it. In July of 2021.

There are ten. Everyone can see the bubble. As obvious as the nose on your face is. July 2020

There is a new date for the 11th. You knew last year that the bubble was going to break, but you didn't know if it would. Every condition that a bubble needs in terms of crazy behavior has been checked. This has been crazy by a large margin. September 2020

There is a bigger buy-in this time to the idea that prices never decline and that all you have to do is buy. The decline will be bigger and better than anything before. November 2020

The Big Short investor's selling spree is a huge red flag, and it's an endorsement for the few stocks he has left.
