How average down works
Averaging down involves buying more shares of a stock at a lower price than your original purchase. This reduces the average price you paid for all your shares, meaning you can reach a break-even point or profit sooner if the stock price recovers.
New Average = (Total Cost of All Shares) / (Total Number of Shares)
