Is this a comment towards people trying to buy the dip or people who are socking money into the market month after month regardless of market conditions? Much like most of your commentary this post is ambiguous and more aggressive than insightful.
If the latter then count me in... a 10%-50% doesn't really worry me all that much. I am 30 and have a very long time horizon. I make over 1m a year at this point and my portfolio as a % of my income is still quite small and can be replenished rapidly. In short, it isn't worth the risk to me to practice anything other than a stable index strategy at this point. Maybe when I hit 10+m i will look into professional guidance... and I can assure you it will not be from a maniac like yourself.
