An intriguing 3-legged options trade occurred in ride-sharing giant, Uber (UBER) last week. This strategy, known as a put spread collar, traded 24,000 times and has an August expiration. The purpose of this trade is generally to protect the downside for those that own the stock. With a put spread collar, the downside loss is limited by purchasing a put spread, while the entire cost of the trade is lowered by selling a higher strike call.
