It probably doesn't hurt that Cliffs went up $4.03 yesterday. That's a gain in market cap of just over half a billion dollars, to $8.70 billion.
Put into perspective, the gain in market cap at Cliffs yesterday alone, in a single day, is equivalent to slightly over five times the total combined market caps of SPQ and KWG at yesterday's closing price.
Taking out KWG and SPQ would be a drop in the bucket.
