It depends on how good you are in reading the news as they are coming, big surge and a big drop always have bad and good news associated with it, it's always been to buy low sell high, but sometimes waiting for the price to drop is not going to happen, it's always a gamble to buy at the price that you think is safe, either way, as long as you are comfortable at your investment, means you invest what you can afford to lose, it will not harm if it goes down after you made an order.
