Summary
Highlights
Many believe the stock market is in a bubble, leading to a high volume of short positions. S&P 500 short interest, as a percentage of total market capitalization, is near an all-time high, currently around 3%. Historically, such high short interest, seen in 2009 and 2016, coincided with market bottoms, preceding significant bull runs. This indicates that high short interest acts as fuel for bull markets, as shorts eventually close positions by buying, pushing prices higher. Hedge funds' record short positions in March further propelled the recent rally as they covered their losses.
Leverage in the market, measured by margin debt as a percentage of total market capitalization, has been rising but is not at extreme levels compared to the period between 2007 and 2017. If leverage were excessively high, a small sell-off could trigger widespread forced selling due to margin calls, leading to a crash. However, current margin levels suggest this is not the case, meaning the market is not overly dependent on leverage.
For those who missed previous rallies and are waiting for a crash, the market's current state may seem like a bubble. However, high prices alone do not signify a bubble; valuation must be considered relativistically. When comparing the S&P 500 to the price of gold, stocks do not appear overvalued, suggesting that the perceived high prices might be due to a shrinking dollar purchasing power rather than inflated stock values. Valuation fundamentally measures how much money a business generates, akin to paying for a 'money printer'.
The Price/Earnings to Growth (PEG) ratio, which measures the price paid for expected earnings growth, indicates that the S&P 500's PEG ratio has been collapsing. A low PEG ratio suggests investors are not paying much for expected growth. Historically, the S&P 500's PEG ratio rarely dips below one, with previous instances (late 2008, late 2011, late 2018) marking market bottoms that led to significant bull runs. The exception was early 2022, which preceded a bear market.
The low PEG ratio in early 2022, which led to a bear market, occurred during a shift from unprecedented monetary easing to tightening, with rising interest rates and liquidity shrinkage. Currently, the situation is reversed: we are moving from a tight monetary policy environment to an easier one, with expectations of lower interest rates and potential bank deregulation. This difference in monetary policy suggests the current low PEG ratio is more likely to signal a continuation of the bull market rather than the onset of a bear market.
While the market might still seem expensive to some, this is a crowded opinion. The current conditions, including high short interest, moderate leverage, and a favorable shift in monetary policy, suggest a higher probability of a prolonged bull market. It's crucial to remain hedged, disciplined, and have risk mitigation in place, but sitting on significant cash in anticipation of a crash might lead to missing out on substantial growth. Missing significant growth opportunities can be as risky as being overleveraged.
