Derivatives are generally used as an instrument to hedge risk, but can also be used for speculative purposes.

Just read the disclosure form:

")Shares were acquired upon the vesting and conversion of Restricted Stock Units, which were received as a grant for which no consideration was paid.

( 2 )Each Restricted Stock Unit ("RSU") represents a contingent right to receive one share of Accuride stock. 50% of the total number of RSU's granted vested on 2/1/12; 25% of the RSU's granted vested on 2/1/13 and the remaining 25% of the RSU's granted vested on 2/1/14."

I am looking at an example where an insider has a quarterly report on the coming Monday and a few weeks ago

filed for acquiring 16,689 shares in non-derivative stock

but on the same day..

filed for disposing of 16,689 shares in derivative stock

So why did he do this is? Is he being conservative to get out or is he leveraging to make more?
