Comparing trading volume to all outstanding Common Stock.
FNMA Common outstanding. 1,159,000,000 Billion (rounded up)
Avg volume trading per day almost 5% = 57,950,000 Million Shares. This is not a lot compared to the whole.
And I would venture to say that over half of the 5% is being traded on a daily basis by day traders.
I think there are a lot of Longs Holding this Stock.
Amazing how this can drop 10 % on low volume of 30 million shares.
