The elite investor David Einhorn blasted market regulators, accused Elon Musk and Chamath Palihapitiya of juicing assets, and praised the GameStop champion Keith Gill in a letter to Greenlight Capital investors this week.

The Greenlight president also highlighted the "Big Short" investor Michael Burry's exit from Twitter and pushed for greater scrutiny of Archegos Capital, the family office that blew up in March. Einhorn's latest letter was obtained by ValueWalk.

Here are Einhorn's 11 best quotes, lightly edited and condensed for clarity:

1. "The Fed wants to be ahead of the curve on the downside to protect the stock market and corporate bondholders the economy. Behind the curve is fine on the way up no matter how frothy the stock market the recovery is." - suggesting the Federal Reserve cares more about stock prices and corporate profits than the economy.

2. "If we swing a little less hard, we should hit more balls." - on his decision to short fewer individual stocks after several of Greenlight's positions were hit during the meme-stock frenzy.

3. "Investors discussing why they think GameStop (or any other stock) should go up or down ought to be encouraged. There is no reason to drag anyone before Congress for making a stock pick." - defending Keith Gill, who goes by Roaring Kitty on YouTube, and his "great call" on GameStop.

4. "The real jet fuel on the GameStop squeeze came from Chamath Palihapitiya and Elon Musk, whose appearances on TV and Twitter, respectively, at a critical moment further destabilized the situation." - Einhorn suggested Palihapitiya had intentionally disrupted Robinhood because it competes with one of his investments, SoFi.

5. "If regulators wanted Elon Musk to stop manipulating stocks, they should have done so with more than a light slap on the wrist when they accused him of manipulating Tesla's shares in 2018. The laws don't apply to him and he can do whatever he wants."

6. "Quasi-anarchy appears to rule in markets. Sure, Dr. Michael Burry, famed for his role in 'The Big Short,' reportedly received a visit from the SEC after tweeting warnings about recent market trends - and decided to stop publicly speaking truth to power. But for the most part, there is no cop on the beat." - complaining that regulators have been defanged and that corporate executives can break the rules with impunity.

7. "Hometown International, which owns a single deli in rural New Jersey ... reached a market cap of $113 million on February 8. The largest shareholder is also the CEO/CFO/treasurer and a director, who also happens to be the wrestling coach of the high school next door to the deli. The pastrami must be amazing." - underscoring the number of questionable companies that regulators are overlooking.

8. "From a traditional perspective, the market is fractured and possibly in the process of breaking completely." - highlighting a dangerous lack of regulation and the risk of casual investors getting scammed.

9. "It was as if Bernie Madoff had been told to pay a small fine and stop ripping off New Yorkers, but to go ahead and have fun with the Palm Beach crowd." - criticizing regulators for slapping the Tether crypto exchange with only a $19 million penalty and a New York ban.

10. "If Congress wants to understand why GameStop stock did what it did, or more recently how the 'Arch-Egos' fund cornered the market in a handful of stocks, it would be better to call to account the absentee regulators and their philosophical backers."

11. "'Arch-Egos' was able to buy up most of the float of GSX Techedu, causing the stock to soar 400% in the face of unrefuted allegations of massive fraud. The SEC has an ongoing investigation of GSX but appears to not have noticed a single fund (or a small group of funds) essentially cornering the market. A traditionalist could say this was market manipulation and transparently illegal."
