Warrant is a contract to buy and sell a certain stock, which has no value in itself, so we must pay attention to the exercise date so as not to miss it like a piece of waste paper. If you take the warrant, the exercise price plus the warrant price is higher than the current stock price, you can resolutely buy the stock. If you take the warrant, the exercise price plus the warrant price is lower than the stock price, you can firmly hold the warrant and wait for the exercise.
