JB- seems like your quite experienced. On your opinion on tech anaylyss. Ofcourse I also think no indicator is perfect otherwise everyone would be doing it but I think it can be used along with money management and some fundamentals. I started investing much later in 2007 but Iv made up for the lost time by reading a ton of books, analyzing markets and also trading. Made some money on the downside in 2008-2009 but the after 2009, the rally has surprised me. I expected stocks to go up but i didnt expect it to go up for so long but every year it keeps surprising people.

On Fundamentals, Although I have big respect for the fundies, in this world we have no choice but to adopt some kind of technical analysis only because many of the big traders and markets are influenced by them. In a sense technical analysis becomes a self fulfiling prophecy.

Piano- The article sounds interesting idea in a bull market, they tested from 2009-2012. I think their approach was buying strong companies.
