Why Equity Markets Run on QE, Not Fundamentals – And Why PE Ratios Keep Climbing
- QE Drives Stock Prices: Quantitative easing (QE) by central banks, like the Fed post-2008 and 2020, floods markets with cash, pushing stock prices up despite weak company profits. - Low Rates Boost Stocks: QE keeps interest rates low, making bonds less attractive. Investors buy stocks, inflating prices beyond fundamentals. - New Competition Hurts Margins: Cheap credit from QE spawns new companies, increasing competition. This cuts profit margins of existing firms, sometimes by 10-20%. - PE Ratios Rise: S&P 500 PE ratio is 29 in August 2025, up from 27 in June, with forward PE at 22.7. Low rates and tame inflation drive high PEs as prices outrun earnings. - Market Concentration: Top 10 companies hold 33% of S&P 500 market cap, similar to 2000 (27%) and 1929 (18%). QE cash flows into large-cap stocks, ignoring fundamentals. - Historical Patterns: Post-2008, S&P 500 rose 400% by 2020; 2020-2022 saw a 100% jump. Profits lagged. QE expectations overshadow weak fundamentals. - Risks of QE Dependence: If QE ends or rates rise, stocks could crash. Weak margins and high PEs make markets vulnerable, as seen in 2022 taper fears. - Conclusion: QE, not profits, fuels stock gains. It drives competition, shrinks margins, and inflates PEs. In 2025, markets risk a correction if QE stops.

Why Equity Markets Run on QE, Not Fundamentals – And Why PE Ratios Keep Climbing
Equity markets seem unstoppable in 2025. Stocks hit new highs. But is it due to strong company earnings? Or something else? Many say quantitative easing (QE) drives it all. QE floods the system with cash. This pushes prices up, not fundamentals like profits. That's why PE ratios rise daily. Here's the story as of August 8, 2025.
What Is QE?
QE is when central banks buy bonds. They pump money into the economy. The Fed did this big time after 2008 and 2020. It lowers interest rates. Makes borrowing cheap. Aims to boost growth. But it also juices asset prices.
How QE Pushes Stocks Higher
QE cuts rates. Safe investments like bonds yield less. Investors chase stocks for returns. Extra cash flows into markets. Stock prices rise. Not from better business. From more buyers with easy money. Studies show QE sparked stock booms in the US and Europe. It creates bubbles. Prices detach from reality.
Why Fundamentals Don't Matter Much
Fundamentals are earnings, sales, growth. In theory, they set stock prices. But QE overrides them. Low rates make future profits worth more now. Stocks look cheap even if earnings lag. QE also cuts company debt costs. Boosts profits a bit, say 5%. But the real kick is liquidity. Markets rise on hype, not hard numbers. Post-2008, stocks soared while economy struggled.
Rising PE Ratios: The Proof
PE ratio is price divided by earnings. High PE means stocks are pricey vs profits. S&P 500 PE is about 29 now. Up from 27 in June. Forward estimate is 22.7. Why? QE keeps rates low. Inflation is tame. This lifts PEs. Prices outrun earnings. Bubbles form. In QE eras, PEs hit highs. Yet another indicator is the top 10% companies commanding a large part of the market cap which happened in 1928 and in 2000 as well. This happens when markets are perfused with the QE money and then it gets parked into large caps at high PE levels without any look at the fundamental numbers.
Data Shows the Disconnect
Look at history. QE after 2008: S&P rose 400% by 2020. Earnings grew slower. Same in 2020-2022. Stocks up 100%, fundamentals weak. Today, with Fed balance sheet still huge, pattern holds. Markets ignore bad news. Focus on QE hints.
Risks in This Setup
It's not sustainable. If QE ends, rates rise. Stocks could crash. Fundamentals bite back. Like 2022 taper fears. Or if inflation jumps, PEs drop hard. Bubbles burst.
Final Thoughts
Equity markets ride QE waves. Not fundamentals. That's why PEs climb. In 2025, with low rates lingering, trend continues. But watch for shifts. When liquidity dries, reality hits.
