Bitcoin Now Undervalued vs S&P 500, According to This Metric

Bitcoin (BTC) is now undervalued versus the S&P 500.

That’s according to a metric that runs an Ordinary Least Squares (OLS) regression of the relationship between bitcoin and S&P 500 over the last 200 days to estimate of fair value for the Bitcoin price based on the current S&P 500 price.

This methodology (an OLS regression of the Bitcoin and S&P 500 prices over the last 200 days) comes up with a fair value of 27,550 for BTC.

At its current price almost exactly $1,000 lower in the mid-$26,000s, bitcoin is currently undervalued versus this estimate of fair value by around 3.7%.

That’s the biggest undervaluation bitcoin has seen versus its 200-day OLS regression-derived fair value to the S&P 500 since mid-February.

Bitcoin and US stocks, particularly growth stocks, have historically had a close trading correlation, with analysts viewing both as speculative risk assets that are sensitive to shifts in interest rates.

US equity markets have been led higher in recent weeks by a surge in big tech stocks amid swelling optimism about the possibility that fast-evolving artificial intelligence (AI) technology will deliver a substantial boost to productivity and profits.

Thanks to the historic correlation between bitcoin and stocks, the more the latter rallies while the former stagnates, the more scope there is for a “catch-up” rally in bitcoin.

Bitcoin was last changing hands close to 15% lower versus yearly highs hit in the $31,000s in April, while the S&P 500 was on Thursday probing yearly highs just under 4,300.

Weakening Correlation Limits Prospect of Bitcoin Catch-up Rally

However, the argument for a bitcoin catch-up rally to the surging equity market isn’t quite as strong as it was a few months ago.

That’s because, while the correlation between the S&P 500 and bitcoin price is still positive, it has weakened substantially over the last 12 months.

This time last year, the 60-day Pearson correlation between Bitcoin and the S&P 500 was above 0.6, as per data presented by

Meanwhile, as of the 6th of June, it was only around 0.14.

Much of the weakening in the two asset classes’ correlation happened in March, when a mini-bank crisis rocked sentiment in the equity sector, but injected a dose of safe-haven demand into bitcoin.

March’s price action was a sign that investors were finally starting to view bitcoin how its long-time proponents have always wanted it to be viewed – as a decentralized and secure alternative to the current fiat-based monetary system.

Indeed, while bitcoin’s correlation to the S&P 500 has been weakening as of late as investors treat the asset more like a hard-money safe-haven like gold, bitcoin’s correlation to gold has been on the rise.

Bitcoin’s 60-day Pearson correlation to Paxful’s tokenized version of gold (PAXG), which tracks the spot gold price closely, was last around 0.22, having recent hit highs for the year above 0.3.
