I last covered Infineon (OTCQX:IFNNY) (OTCQX:IFNNF) in June; at the time, I put out a Buy rating based on fundamental undervaluation. However, the stock has fallen around 20% in price since then. My investment strategy is now evolving to incorporate more elements of market psychology, and whilst I do emphasize fundamentals as the foundation of valuation analysis and Buy ratings, I believe that without sentiment analysis, one is exposed to high levels of potentially unnecessary losses if investing on fundamentals alone.
