you're right. One day morning The Wall Street Gang suddenly find out the true value of yahoo. The day is closing.
It looks like a plot involved to reveal VZ bidding price on purpose, so shareholders lost confidence on Yahoo value.
If CASA had short position on CLF in the early day, does he have to report on Form 4? If your assume is correct, then CASA lost was not so enormous like the paper filing. Thanks.
Sentiment: Strong Buy
