(The parallels between the 2007 market top and today's investment environment are eerily similar. Emerging markets outperformed U.S. stocks by 30% then and do so again today. Credit is being pumped in the system and China's economy seems to be the key to new prosperity. According to history and many other indicators, your portfolio is in serious danger. Fool me once, shame on you; fool me twice, shame on me." Yet another chapter of the love-hate relationship saga between investors and the stock market is about to be concluded . and it won't end with "they lived happily ever after." Investors, obviously, are forgiving people. Within a period of 18 months, the S&P 500 (SNP: ^GSPC), Dow Jones (DJI: ^DJI) and Nasdaq (Nasdaq: ^IXIC) reduced investors' portfolios by over 50%. At that point, most hated the market. After showing some good will for a comparatively short five months (March - July 2009), investors are once again falling in love with the stock market. Like a crafty mistress, the market has investors wrapped around her finger. As far as relationships go, the market's recent shenanigans compare to making up for an act of infidelity with a bar of chocolate, a gross imbalance. But it doesn't stop here. Investors are starting to fall for the same tricks that shaved 50% off their wealth last time . "fool me twice, shame on me.")"Simon Maierhofer
