How to measure if the stock market is overvalued.

Using the Shiller PE Ratio, a 10-year Cyclically Adjusted Price Earning Ratio (CAPE Ratio) of the S&P 500 Index, and the S&P 500 Dividend Yield are excellent ways to measure if the stock market is overvalued.

3 signs the stock market is overvalued.

  1. When earnings growth is slowing down, but stock prices are increasing rapidly, this is a sign that the market may be overvalued.
  2. Another sign of an overvalued market is when shares are trading at high price-to-earnings ratios. A high P/E ratio indicates that investors are willing to pay more for a company’s earnings.
  3. The last sign we will discuss is when the dividend yield is low. A low dividend yield means that companies are not paying out much in dividends relative to their share price. This can signify that companies are using their cash to buy back their stock or engage in other activities rather than returning money to shareholders.

The historical context of stock market valuation.

Here is a chart from 1860 to 2021 comparing the U.S. Long Term Interest Rates to the Shiller Price Earnings Ratio of the S&P Composite Index. Interestingly, the correlation of Long Term Interest Rates being at extreme lows and stocks being extremely overpriced.

The Price Earnings Ratio line shows that in relation to earnings, stock prices were too high in 1901, 1929, 1966, and 2000. We know the stock market was overvalued at this point because the market went through a correct/crash after reaching these highs.

Research shows that the 1929 stock market crash and the 2000 DotCom crash were because of poor institutional risk management, which caused equity bubbles, leading to an overvalued stock market.

So what can we learn from this?

If we see the Shiller CAPE PE Ratio of the S&P Composite rise above 35, then stocks may be overpriced. Be very wary of an overpriced market. The Shiller PE Ratio shows us how stocks are priced relative to their actual earnings. So a market PE of 20 would mean, based on the capital invested, it would take those companies 20 years to pay back the investor. Or viewed another way, an investor is willing to pay 20 times the company’s earnings for a stake in the business.

Are stocks overvalued? S&P 500 Dividend Yield.

The Dividend Yield of the S&P 500 is 1.69, near an all-time low suggesting that stocks are overvalued historically.

But the nature of the company’s paying dividends has changed over the last 100 years. Today, only 25% of companies pay a dividend, and the dividend yields are smaller than 50 years ago, largely due to the stock prices being historically high compared to earnings.

What happens when the stock market is overvalued?

If a stock market is overvalued, there are two possible outcomes. Initially, governments will try to manage the situation to ensure an orderly return to balance using conservative fiscal and monetary policy. However, a surge in inflation, a financial shock, or governmental attacks on the corporate sector could change the balance and cause a crash in equities.

How to know if a stock is overvalued?

To understand what it means for a stock to be overvalued, we first need to understand what valuation is. Valuation is the process of determining the worth of an asset. Regarding stocks, this usually refers to estimating the future cash flow the stock will generate and then discounting it back to present value.

There are various ways to value a stock, but one of the most common methods is the price-to-earnings (P/E) ratio. This ratio takes the stock’s price and divides it by the earnings per share (EPS). The EPS is determined by dividing the company’s net income by the number of outstanding shares.

So, what does it mean if a stock has a high P/E ratio? That typically means that investors expect high growth from the company in the future and are willing to pay more for each dollar of earnings today. Conversely, a low P/E ratio could indicate that investors expect slower growth or are worried about potential problems with the company.

Now that we know how to value a stock, let’s talk about what it means when it is overvalued. The stock is overvalued if a company’s stock price is higher than its fair value. In other words, investors are paying too much for each dollar of earnings today. This can happen for various reasons, such as investor optimism or hype around a certain company or sector.

Paying too much for a stock can be dangerous because it increases your downside risk. If the company doesn’t live up to expectations or there’s some negative news, you could see significant losses in your investment. That’s why it’s important to be aware of overvalued stocks and to do your research before investing your hard-earned money.

How overvalued stocks affect investors.

Overvalued stocks can have several effects on investors. Perhaps most obviously, overvaluation can lead to losses if stock prices eventually drop back down to their intrinsic value.

Additionally, overvalued stocks may be more volatile than their underlying fundamentals suggest, meaning they may be more susceptible to sharp price movements (up or down) in response to changes in market conditions.

Finally, overvalued stocks may be more prone to “corrections”—meaning a sustained 10% or greater decline from recent highs—than other stocks.

How to Invest in an Overvalued Stock Market?

Investing in an overvalued stock market involves a decision only you can make. You can continue investing as stock markets can stay overvalued for a long time or diversify into other investments or cash.

1. Continuing to invest in an overvalued stock market.

As the stock market’s default direction is up, if you remain invested, eventually, the market will recover, and you will continue to make money. Suppose you are regularly contributing to your stock investment. In that case, you will be able to take advantage of Dollar-Cost Averaging (DCA) to accumulate more equities at lower prices as the market falls. This option allows you to remain invested without having to time the market.

This solution has drawbacks, especially if you are close to retirement and do not have the time to wait to recoup your losses. This leads us to option two.

2. Diversify your investments into other assets.

Timing the market is not for the faint-hearted, and most people get it wrong. Government bonds have staged a comeback due to increasing interest rates, so they now represent a good option for diversifying your portfolio.

There are technical systems to help you judge whether the time is right to cash in your investments and move to cash. The MOSES System that I have developed is one such system, I think it is good, but no system is fool-proof. I have also developed the Liberated Stock Market Fear & Greed Index to help you decide if the market is in Greed Mode (a Bull Market) or Fear Mode (a Bear Market).

But as the Economist states, “If there were reliable trading signals, everyone would follow them. And then there would be no one to sell to at the top and no one to buy from at the bottom.”
