As has been discussed, Berkshire is buying $10bn of newly minted Alphabet shares at $350 apiece, a slight discount to market price. (which was about $376 then, about $363 now)

I've been pondering this a bit more since the news came out, since the valuation seems quite stretched, at least superficially. Those shares are being bought at 10.6 times trailing sales per share, versus 15 years of typical numbers more like 6-7, and a headwind of likely falling net margins (meaning the fair P/S ought to fall) as the capex jumps and the depreciation line soars.

It seems to me that their stock price is affected by the current bubbly AI narratives, which is some unknowable mix of "transient" and "justified".

On the other hand, it's about the best moat out there, if you ask me. They absolutely print money, and recent business results are knocking it out of the park.

So, my question -
Would you be a buyer of Alphabet shares at $350? Assuming a medium to long hold, of course.
