When correctly identifying big money flow into a stock, in order to ride the future trend, you sometimes encounter events where the entire company actually got purchased.
the graph will not load but this is the reason and result:
"Level 3 shareholders will get $26.50 a share in cash for approximately 1.43 shares of CenturyLink stock for each Level 3 share they own. That implies a price of $66.50 per Level 3 share, a 42% premium to where they traded on Thursday before reports of the deal."
Company was purchased, good catch, moving on...
