$ATNM has been on quite the roller coaster the last few days, and I’ve been reading up on market manipulation as a result. I am a newby to investing, but work in the field of databases and dashboards, so I recognize screwy data when I see it, but have no idea how to interpret in the context of stocks. I think the main Dr KSS comment thread is tired of the topic, but I hope a few of you will join me.
I found a fascinating article on short attacks:
NASDAQ just published historical short data for ATNM ending on 5/15
The really big $1,000,000 shorts started with settlement dates at the end of Feb, and the big price drop was intrasession Feb 5th & 6th. The shorts kept growing by 500,000 shares every 2 weeks after that- On the last date they were up to 2,526,000+. Granted, the price dropped $2.79 during that period which invites shorts, but is this normal behavior for a low volume stock?
Now there is one relatively big call left with expiration date of June 19 and strike of $2.5. It’s not a put, which is what I would expect with short attack, but I have very little visibility into very recent past options- say the last 6 days.
There is a graph on Schwab’s options tab that shows the call/put ratio and on April 22 or so there was a huge spike- like 7.40- where all other dates were flat low values. What does that mean?
The big shifts in price keep happening right on the boundaries between normal sessions and pre/post sessions with a huge transaction that doesn’t show up on 1 day graphs, you have to look at 5 day graphs to catch them.
So what do you think- is the last few days of dropping like a rock on fairly good news a result of manipulation, short attack or otherwise?
What kinds of manipulation have you seen in other stocks?
