Cannabis stocks are notoriously volatile. On Aug. 1, 2018, Tilray — a Canadian company that calls itself "one of the largest and most sophisticated producers of premium medical cannabis in the world" — was worth $1.66 billion.

By the numbers: A mere 35 trading days later, on Sept. 20, it was worth $16.37 billion. Today, it's worth $3.3 billion.

Look past the day-to-day volatility in individual stocks, however, and a bigger picture appears: The marijuana sector as a whole, as valued on mostly Canadian stock exchanges, is not only enormous but pretty stable in size.

  • The 8 largest companies, collectively worth $39 billion today, have been worth somewhere between $36 billion and $44 billion pretty much all year.

The bottom line: This might well be a bubble. But if it is, we've moved past the get-rich-quick stage. Pot valuations aren't soaring any longer — but they're not declining, either.

Correction: The chart at the top of this story previously misidentified one of the cannabis companies. Its name is Curaleaf, not Cura Cannabis.

Moderna's COVID-19 vaccine is effective against new variants of the virus that first appeared in the U.K. and in South Africa, the company announced on Monday.

Yes, but: The vaccine was as effective against the strain from U.K., but saw a six-fold reduction in antibodies against the South Africa variant. Even still, the neutralizing antibodies generated by the vaccine "remain above levels that are expected to be protective," according to the company.

Xi Jinping warns against "new cold war" in Davos speech

Chinese President Xi Jinping warned that a "new cold war" could turn hot, and must be avoided, in a speech on Monday at World Economic Forum’s virtual “Davos Agenda” conference.

Why it matters: Xi didn't refer directly to U.S.-China tensions, but the subtext was clear. These were his first remarks to an international audience since the inauguration of President Biden, whose administration has already concurred with Donald Trump's determination that China is committing "genocide" against Uyghur Muslims, and issued a warning about China's aggression toward Taiwan.

Dominion files $1.3 billion defamation lawsuit against Rudy Giuliani

Dominion Voting Systems filed a defamation lawsuit against Rudy Giuliani on Monday seeking $1.3 billion in damages for his "demonstrably false” allegations about the company's voting machines.

Why it matters: Giuliani led former President Trump's efforts to overturn the results of the election and spread the baseless conspiracy theory that Dominion's voting machines flipped votes from Trump to Joe Biden.
