I just did my little part by buying 180 shares, which was all the "cleared" funds I had in my account today. More will be clearing later in the week and I will do more buying. I always do this buying in "dribs and drabs" as much as possible every day during a market correction. We knew there was doing to be a market downturn due to the budget controversies in Washington, so I sold some stock every day last week in order o have funds clearing into the account this week.
I trade/invest for most of my livelihood. A major part of successful trading is pure psychology: you buy when others are selling. Even if you're buying "dribs and drabs" the act of committing more money reinforces your commitment to maintain your position during a panic. It tend to prevent you from doing anything outrageously stupid like unloading a big position at the exact bottom.
At any rate, let's keep our heads cool during this government "shutdown" (if it really is a shutdown and not just a political sham). Let's try to be smart in the markets even if the nutso's in D.C. can't get THEIR act together.
