Retired 15 years. Basic strategy is to emulate Warren Buffett. Invest or trade in sector leaders to own at lower prices by selling put options below and much below the strike price. When the stock drops below the strike price I buy the stock at the adjusted price, below the market when I initiated the put trade, and even lower reduced by the premium received. Most often though the stock trades above the strike price and I build cash, winning premiums. To reduce risk sell puts at much lower strike prices. SPY puts are favorite trades because very high volumes and low spreads provide better pricing execution, liquidity, and available time choices.
