PCG is down 3.5% aftermarket on no news. This has happened several times. My guess is that the trust is selling 30 mm+ shares again in a bulk trade. The first few times they did this it weighed on the stock for a short period of days to weeks. However the past few times, since PCG joined the S&P 500, the decline only last a few hours. We will see tomorrow. I bought a bunch last time, Dec 15th. Traded out within hours. Bought 4X more tonight. Wish me luck. Should trade lower pre-market.
By the way. If the trust sold 1 MM shares a day, they would likely not need to take a haircut at all IMO now that PCG is in index.
