With the dollar cost averaging strategy.
# We will build a long-term position during the period when the price is trending down. We will not miss the train when the price starts to rise, and we will have mitigated some of the risks of buying during a period of falling prices. However, we must take into account that this strategy may involve risk - we may go to buy during a period of falling prices despite all that. Some investors prefer to wait until they are sure of the end of the price decline period, and then start the deal. If the expiration of this period is certain, the average cost (or share price) may rise, but in return the risk of the price falling will decrease significantly.
