What are you invested in? I think market conditions are particularly favorable at the moment for various types of leveraged products, but I haven’t seen anything with 20% yields that I’ve wanted to commit capital to.
Regarding the original question, do you mean a 20% drop from current levels, or 20% drop from a future high of SPX? If it’s the first one, chances are never in our relevant timelines. The market will most likely keep going up in the mean time, and a bigger and bigger decline will be needed to create that event. If it’s the second condition, then the probability is much more likely. However, we will need to see different geopolitical conditions, such as destabilization in China, or revolution in the West that will convince governments to accept nominal asset value destruction rather than inflation or negative interest rates.
