The Nifty Fifty is before my time, but I’ve read a decent amount on that period and it rhymes a lot with today. Some businesses are so good and so promising that you can “invest and forget.” Prices don’t matter. I wonder how many of those businesses are still around today. Maybe those who did buy have forgotten.
The underlying pattern is almost always the same. Promising new businesses emerge and are deemed can’t miss. A new generation of investors who haven’t experienced similar periods explain that this time is different than the last time,. New investors can see nothing but upside while paying lip service to risk. They can’t see what could derail the current environment. That’s probably the insight experience teaches best. No one, or at least very few, can see the catalyst for a turn.
The justifications are always similar. As are, unfortunately, the inevitable outcome.
Risk is omnipresent. The higher the price and valuation, the less margin for error in performance and expectations. High prices magnify risk.
