Case in point, the dark Thursday a few weeks ago when the market crashed horribly and inexplicably for a brief half hour or so (I actually saw the actual 900 point dip totally by total chance and thought Google Finance was broken!) My immediate reaction was to buy buy buy! But unfortunately my brokerage website had some high volume usage problems so I missed the opportunity to "strengthen" my current positions. But of course, the common investor sold at this time in panic and thousands of people lost a lot of money that day once the dust settled. I would hate to be the one triggering a market price sell order at that exact moment when the market dipped! Lesson learned in many ways.
*Always do limit orders even if it's at market price to avoid inexplicable swings in pricing.
