I beg to differ...I'm not going to argue with you that they haven't been on the level of 2000 or 2008, but this market has seen a series of 15-20% rallies and declines (a few very sharp and sudden moves - Aug 24, 2015 & early-mid Jan 2016)...Where I agree is that the Fed has stepped in either via backdoor agreements of "open mouth operations" to keep things from progressing to the level of those other two episodes...Unfortunately, the more they "condition" the market to expect a neverending series of monetary dovishness, the worse the outcome...so I completely agree with you there.
I don't know how far back your trading goes but when I got into this business we use to get 2 to 3 10% to 15% corrections a year and they never even got media coverage. Today a 10% correction gets sunday night CNBC specials called Black Monday. They really have conditioned you to think that 10% pullbacks are like a sign of the coming apocalypse. But 10% corrections are normal and usually don't even show up on long term charts as even a blip. It's the fact that the market has been so dead that by "relative comparison" 10% corrections feels like the end of the world.
