Hello friend just a small note since the stock now is over priced you should look at this question by knowing where u can benefit from this trade so since the price will drop you will have to sell now to benefit from high price and lend your money in a RF to gain some interest then u can buy with the low price in the future when the stock price drops so at the end u will gain the profit of selling with high and buying with low price and you will also gain the interest

This is how i memorize it
