Just Tell Me The ‘Why’

No matter how badly we want to answer the "Why?" question, it's almost never a good idea to attribute a given day's price action to a single, proximate cause. While it's all too easy to point fingers at readily identifiable macro catalysts (e.g., Evergrande or generic "inflation worries"), it's never that simple.
