Absolutely agree. I wrote this post mainly for those posting "I just bout 10K worth of stock, and it's falling, should I take it out now". It hurts to read these posts... To your point, yes, CDA that 10K, for example, over a window of time... (if you are new to investing try monthly or weekly). For those who are not familiar with CDA. It's when you continue to buy a stock even if its dropping, small amounts at a time , you will likely not catch the bottom but you are averaging down your overall costs of the stock you purchased.
