Often there is no lesson to be learned, each stock is unique.
Stocks go up and down, it is what they do. Run with the bulls, short when it gets nuts.
Tired of most technicals, volume and news is all I care about.
I am the CEO and founder of Market Prophit, a financial big data analytics company that analyzes stock-related conversations in social media and generates real-time sentiment (bullish/bearish) signals and buzz for retail and institutional clients.
