This is why all of these media outlets use words like "as" and "after", and never "because of". They do all the "post hoc" lifting and assume that the reader will automatically add the "ergo propter hoc".
There's probably an algorithm out there that just writes financial news all day using the MadLib:
"[COMPANY] stock [RISES|FALLS] amid [NEWS]."
All you have to do is foreach company, look up whether the stock is up or down, and then copy the first news search result that comes in related to the company. Bam, you have a headline for any financial news site.
"Google stock tumbles 8% after its"
which every consumer of media reads as
"Google stock tumbles 8% because its"
