The beauty of history is that is shows us one hand that the future is unpredictable (think of M-Pesa in 1999 or even 2000s) and also that there is nothing that is new (everything is cyclical).
A good example is fuel price controls which ended changing the strategic landscape from a volumes game to a margin game.
Banks maybe down now but with readjustment and innovation they may actually come out stronger. Lower NPLs, better credit analysis, creating of a credit scoring system, better collateral management etc
This law is a blessing in disguise. The shock that was needed to push innovation further.
3 quotes come to mind at this moment in time. "When there is blood on the streets...""Greedy when others are fearful...""The risk of an investment depends on the price you pay..."
Investment philosophy development in progress...
