Question 7

What is the risk of dollar cost averaging into RIO?

Accepted Answer

Always invest within your risk tolerance and consider your overall portfolio diversification.

Question 8

What is the Rio Tinto Group dollar cost averaging strategy?

Accepted Answer

Standard DCA invests a fixed amount ($100/week or $433/month) into RIO at regular intervals. Enhanced DCA improves on this by using RSI (Relative Strength Index) signals to increase buy amounts during market dips (oversold conditions) and reduce or skip purchases when the stock is overextended. Over the 5-year backtest, this timing approach has delivered 11% higher returns than standard DCA while deploying more total capital into RIO.
