Question 4

Is DCA into VRTX worth it?

Accepted Answer

Based on a 5-year backtest, DCA into VRTX returned 43% with standard weekly purchases. An intelligent DCA strategy that buys more during dips returned 47% over the same period — a 5% gain in return, while deploying a similar or smaller amount of capital.

Question 5

How many shares of VRTX would I have after DCA for 5 years?

Question 6

How does VRTX DCA compare to the S&P 500?

Accepted Answer

Enhanced DCA into VRTX returned 47% over the past 5 years. The S&P 500 (SPY) returned approximately 53% over the same period. VRTX's performance reflects its volatility as a healthcare asset. Enhanced DCA outperformed standard DCA by 5%, demonstrating the value of intelligent entry timing during market dips.

Question 7

What is the risk of dollar cost averaging into VRTX?

Accepted Answer

Past backtest performance does not guarantee future results. VRTX is a healthcare asset whose price can fall as well as rise. While DCA reduces timing risk by spreading purchases over time, losses are still possible if the price declines significantly. Always invest within your risk tolerance and consider your overall portfolio diversification.

Question 8

What is the Vertex Pharmaceuticals Inc. dollar cost averaging strategy?

Accepted Answer

Standard DCA invests a fixed amount ($100/week or $433/month) into VRTX 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 5% higher returns than standard DCA while deploying less total capital into VRTX.

Period	Standard DCA	Enhanced DCA	Alpha
