Investment Fallacies explained by an industry insider

Excellent video of a data analyst from a hedge fund explains and unfolds the sales pitch of "holding for the long run".

Basic summary- While indexes have rallied over the decades, most included individual companies had gone bankrupt and replaced by new ones, termed "survivor bias". Therefore long-term holding does not necessarily offer any lower risk. If you bought at a top (e.g. July, 08), this might take you at least 10+ years to break even, inflation adjusted.
