Subject: Re: SNOW - hold forever?
BRK owns about $1 billion worth of it purchased in 2020 for $735 million, so up about 40%. ...

Is that right?

cf. http://www.datahelper.com/mi/s...

I haven't dug into the relevant original documents myself, but if that post of DTB's is right, the purchase was ultimately 6,125,376 shares at $120.00 for $735.045 million.
With SNOW now trading at $149.50, that shareholding is now valued at about $915.7m, up only 24.6%.
So your "about $1 billion" sounds close, but the "up 40%" sounds dodgy.

Given the size of the IPO pop, it's not particularly surprising that the hype has worn off.
Which says nothing either way about the prospects of the firm, of course.
