If you back tested and you re confident in your analysis, more power to you! I am yet to find a truly diversified portfolio that can generate good returns for me...

My back tests and analysis are showing that I am not OK with buy and hold, because I don't want to stomach 50% draw downs or to wait 15 years for the NASDAQ to bounce back...

I am not that risk tolerant and I might need to sell some of my investments for medical, travel, even early retirement...

That's why I like to buy when the market goes up and sell when it goes down and be cash during crises like the dot com bubble and 2008 financial crisis... you can always buy them back on the way up when the trend changes...

Well, yeah. If you are not risk tolerant you shouldn't be investing in the stock market.

No Sir, you should invest in the stock market according to your own risk tolerance! For me it works perfectly and I am very happy with my own strategy ;-)

The description of your strategy (which sounds identical to momentum trading) is a quintessential very-high-risk-picking-up-pennies-in-front-of-the-steamroller approach.

one thing for sure is that you have no idea what my strategy is and I am not about to tell you either...

You described it two posts up. Buying on upswings selling on downswings.
