stock puts

When you buy a stock put for a stock, it means that you are buying the right to sell the stock at a certain price by a certain date. It's almost like buying insurance on the stock - if the stock goes down below the price you chose, then you can sell it for that price and you don't lose any money. If the stock stays above the price you chose, then you don't have to use the put and you can just sell it if you want. It helps you make sure you won't lose too much money if the stock drops.
