No disrespect, but your comments make no sense.
I look at fundamentals, but i have learned over time that charts tell alot. Think about this - the fundamentals are known to everyone. And its what you dont know that can hurt you in the market, not what you know because what you know, everyone knows, and so its priced in (in most cases)
You may be right, if retail news was better, stocks might not have tanked. But the news was bad. Thats all that matters. What its telling us, is the consumer is weak. Can you spell RECESSION> Because we are probably in one already. Everyone talks about great unemployment numbers and all that and how we cant be in a recession. But these are all lagging indicators. By the time retail news is good again, and unemployment numbers are bad again, the recession will be almost over.
Which brings me to your comment - "dont think todays drop was preciptated by prior price action, but instead the very bad retail sales numbers".... well, think about that - the prior price action was IN ANTICIPATION of bad retail numbers due to a slowing economy. Thats why the charts are important , maybe even more important than the fundamentals... because the prior price action was caused by all the hedge funds and institutional investors who have the resources (research, channel checks, etc) that led them to realize that the economy was slowing before it became news.
Sorry for the long response.
