Ken is a pessimist of sorts and has a strong belief that the US market is wildly overvalued currently, and that no vaccine for the virus will prove to be effective. Because of this, he wants to bet very strongly and aggressively (gaining as much personal potential upside as possible) on a US stock market collapse by trading the S&P 500 via the SPY ETF. Which of the below trades for Ken makes the most sense given his strong beliefs?

		Buy calls on the SPY with a strike price of $450 expiring on Dec 31, 2022.
		Sell calls on the SPY with a strike price of $450 expiring on Dec 31, 2022
		Buy puts on the SPY with a strike price of $280 expiring on Dec 31, 2022.
		Sell puts on the SPY with a strike price of $280 expiring on Dec 31, 2022.
		Buy the SPY ETF and buy the $280 put expiring on Dec 31, 2022
		Short sell the SPY ETF, and sell the $450 call expiring on Dec 31, 2022
