“If the market gets negative news and the market shrugs it off and it continues to go up, this is a bullish reaction because it means the market has already discounted the news. On the other hand, a sign of a fully priced market is one that reacts poorly to good news.” - Marty Schwartz
If you haven`t read Marty Schwartz book, "Pit Bull" I will highly recommend it. It should be one of your picks for this summer. You can even read it on the beach as there are no charts or complicated stuff. Pure trading and emotion.
Have a great day!
