I went looking for the stat that would let me sneer at this one. It isn't there.
$CODX is +40.53% in the after-hours session on a $3 million market cap with 7 million shares in the float. Today's 8-K carries Item 2.02, the earnings item, with a Regulation FD item beside it.
The symbol's own record: 44 prior sessions that opened with a gap up of 5% or more. It closed above that day's open 43% of the time and below it 52%. Median open-to-close, -1.18%. Near enough a coin, and a coin is no edge for the buyer or for the man shorting him.
That leaves one thing in this story holding any information: the exhibit behind the item number. The 8-K label says results were reported. It does not say what they were, and neither does a 40% bid on a float that small.
A history that won't pick a side is still a finding. It just doesn't come with a trade attached.
