What does this statement regarding put options mean?
The trader has purchased 1095 options, each of which is a contract which entitles him to sell 100 shares of Cisco stock for $16 a share. He paid $71 for each contract (71 cents a share x 100) which is roughly $78k total. He will get $109,500 for each dollar below $16 Cisco's stock is when he exercises it (he can buy the stock for the going rate and then sell it for $16 immediately), or he can sell the option itself to someone else for a similar gain (usually a little more, especially if the option has a long time until it expires). If the option expires when the stock is over $16/share, he gets nothing; i.e. the original $78k is lost. For reference, Cisco's stock was trading at $17.14/share as of market close on March 18, 2010. The share price had recently been boosted by the recent news that they would be paying a quarterly dividend. It has been heading mostly downward since February 9, after they announced that they're not expecting profits to be as good as the analysts thought they would be: they claim that people aren't buying too much networking equipment just now, and they're also facing mounting competition from the likes of HP and Juniper for switches, and Aruba / HP / Motorola for wireless devices. They may lose market share or need to cut prices, hurting profits. Either way, there's certainly a real possibility of their stock going below $16 in the next few months, so people are willing to pay for those options.
