We don't tank, unless the conditions that created the chart change. The chart is extremely long time frame. The quantified dollar value price swings could easily wipe out most accounts on that time frame. Its easier to just go with the short term/intermediate term trend. Go where price takes you.
Never look for the tank. The fed should just keep pumping us up indefinitely in the long term. If you have doubts, wait for a dip and then buy. Short at your peril!!
whenever FED tightens their monetary policy 1. QE3 should end by early 2015 at the latest 2. fed funds should be hiked to 2% by early 2015 what we know about recent stock bubbles: nasdaq dot com bubble popped Q1 of 2000 subprime bubble popped Q3 2007 In both of these bubbles, the fed funds rate was hiked to >6% before they popped. We're at 0% fed funds right now. Volatility is low right now. Check out QQQQ, volatility in 2013 is the lowest since 2005. Also, the public isn't in the stock market right now. There is still uncertainty and not a lot of hubris, which is prevalent during the final phase of a bull cycle. 2016 maybe, maybe not, wait and see
The channel back then had little volatility, was tight, much easier to break, this is a whole different animal.
The "tank" comes first, then "the conditions that created the chart" comes after. Would you like to guess why I stated that?
