Monster Stock Rally, Blowoff Top then Massive Stock Crash?

In the last post, this blog speculated that we are nearing a Major Market Top and will hit the third peak in a Triple Top, and we may see declines and stagnation for many years.

But what if, instead of a Triple Top Reversal, what if we break out of the previous highs on the S&P 500 (around 1550-1565 on the S&P 500 set in the year 2000 and 2007)?  Then, we will have a very bullish Triple Top Breakout.

We could even be experiencing an Ascending Triangle Formation.  At the end of the Ascending Triangle, stocks could breakout upwards, a bullish sign.

But can this really be sustained?  In previous blog entries, this blog mentioned that there are many headwinds from a National Debt out of control and now at over 100% of GDP, and the Baby Boomer Demographic Retiring. 

This could be part of a major Blowoff Top (like a Volcano) where the mother of all rallies, a massive major rally will be followed up by major stock market crashes and declines.

(The Run-up could be spurred by the Fed continuing to print money (with QE3, and other programs), and short covering rallies as people short near the S&P 500 all time high, and possibly an economy that looks to be improving despite all the headwinds in the market.)

Will we be following Japan's lead (Nikkei 225) if we follow this Blowoff Top Pattern?

Look at the massive runup in stock prices in the Nikkei 225 from 1985 to 1990, and then a multi-decade set of stock market declines and massive crashes.

The U.S. S&P 500 stock index is now (Thursday, September 13, 2012) at 1459.99, is only 7% from the all time high of 1565.
