Markets have consistently experienced “100-year events” every five years. While I spend a significant amount of my time on analytics and collecting fundamental information, at the end of the day, I am a slave to the tape and proud of it.

I see the younger generation hampered by the need to understand and rationalize why something should go up or down. Usually, by the time that becomes self-evident, the move is already over.

There is no training — classroom or otherwise — that can prepare for trading the last third of a move, whether it’s the end of a bull market or the end of a bear market. There’s typically no logic to it; irrationality reigns supreme, and no class can teach what to do during that brief, volatile reign. The only way to learn how to trade during that last, exquisite third of a move is to do it, or, more precisely, live it.

Fundamentals might be good for the first third or first 50 or 60 percent of a move, but the last third of a great bull market is typically a blow-off, whereas the mania runs wild and prices go parabolic.
