To be clear, our sale of $GOOG was not a bet against the company. We are very bullish long term on Alphabet. But at current valuations and in light of our finite capital base, we used $GOOG as a source of funds for $MSFT. https://t.co/0ePZI8p3Bh

I did not blame retail investors for PSUS’ and PS’ price drop. I did explain to the media that we had chosen to favor retail allocations over institutional orders by giving retail investors 100% allocations and cutting back institutions. In most deals, retail investors receive a smaller percentage of their orders than favored institutions. Because the stocks opened late in the day at 1:55pm, investors who received more shares than they wanted were forced to sell in the last two hours of the trading day in order to have the cash to settle their orders the following day. This likely led to dumping of the shares of both PSUS and PS before the market closed. I was not blaming retail investors. I was simply explaining what we believe had occurred. We just did not appreciate this dynamic in making our allocation decisions.

An excerpt from my interview with @CNBC on $PSUS and $PS. I bought 500,000 shares of $PSUS and 800,000 shares of $PS yesterday in the open market. PSUS trades at a large discount to its $49 cash per share and PS trades below the price, $26.25, at which we sold a 10% interest
