When the markets go down the best strategies to use for option trading is Buy Put Option, Sell Naked Call Option or Bear Put Spread. The Buy Put Option instead of shorting stocks and risking a margin call you buy a put option. Buying a put option is the same as buying call options but you profit when the stock goes down rather than up.
Sell Naked Call Option means instead of buying put options you sell short call options and make the entire amount from selling the put options if the stock goes down. Bear Put Spread is when you buy put options at the money and sell short out of the money put options within the same month. This strategy provides profits when the stock falls or stays the same.
