dollar cost averaging

The idea was brought up this evening at my school’s investment club meeting that we purchase stocks using DCA because of the volatility of the stock markets. Transaction costs wouldn’t be an issue as we do not pay any commission on our trades. With this being said, do others have an opinion whether this would be a viable approach to investing with a stock portfolio of $100,000. Any thoughts would be appreciated!!

Sorry, all I’ve been reading about is IPS’ al la L3 ciric. What is your time frame for liquidations. DCA is great if you have time, and your investments will INCREASE in value as most do over time and hence you will be in at a lower costs basis. However if you have a short time frame your investments could continue to DECREASE overtime, in which case the actions are akin to doubling down.
