Are you feeling a bit giddy right now? Perhaps even a tad euphoric? No one could blame you if you were, given how red hot the stock market has been over the past few months.

S&P 500 & My Phoenix Portfolio's Top Winners Since March 23rd Low

Right now what some analysts have dubbed the "hopium" rally, driven in part by TINA (there is no alternative), FOMO (fear of missing out) and QE infinity, has led to some of the highest market valuations in US history.

On Forward P/E Basis, S&P 500 Is Approaching Severe Bubble Territory

(Source: Brian Gilmartin, Reuters/Refinitiv/IBES/Lipper Financial)

How historic is this hopium meltup?

The current record for the most overvalued market in history was set on March 24th, 2000, when the S&P 500 hit a forward P/E of 27.2, 66% above the 25-year average of 16.4.

If the S&P 500 rises just 9.6% more, then it would achieve a forward P/E of 27.3, and set a new record for the most overvalued market in US history.

But just because we're either in a bubble or rapidly approaching one, doesn't necessarily mean the market will necessarily correct soon.

According to research from JPMorgan (NYSE:JPM), Bank of America (NYSE:BAC) and Princeton

This is why valuation alone cannot be used to time the market with precision or consistency. What higher valuations do tell us is that future long-term returns are likely to be far smaller.

At the end of May, the forward P/E on the market, by JPMorgan's estimates, correlated to expected five-year returns of near zero.

If we exclude the Dot-Com bubble, then the 20-year average blended P/E for the S&P 500 has been 17.0, the market-determined fair value for stocks in the modern era.

If earnings grow as expected through 2022 and the market returns to the value hundreds of millions of investors, risking real money, have determined is long-term fair value, then the consensus return potential over the next 2.5 years is about 3% CAGR.

I define a bubble as when forward two to three-year consensus return potential is zero or negative.

So on a blended P/E basis, we're not quite there yet, but we're darn close.

In a market that seems to have lost its senses, and is driven by irrational exuberance and blind hope that nothing bad will happen over the next 2.5 years, why am I still buying stocks?

The Biggest Bubble In US History Still Provided Plenty Of Great Buying Opportunities

(Source: YCharts)

From mid-1998 to March 24th, 2000, quality blue-chips like Realty Income (O) and Berkshire (BRK.B) (NYSE:BRK.A) severely underperformed the market and tech stocks shot to the moon.

Foolish momentum traders (myself included at the time) dreamed of 100% annual returns every year.

As a nine-year-old investing my life savings into the tech bubble at the time, I recall asking my mother, with all earnestness "Where will I invest my trillions in a few years?"

Oh, had I known then the three kinds of risks all equity investors face.

Had I chased not mad dreams of fast fortunes but stuck to a disciplined strategy built on the time-tested principles of true wealth compounding, I would be a multi-millionaire by now. Realty Income in March 2000 was trading at 7X FFO, about 50% historically undervalued at the time. Berkshire was trading at similar discounts to its historical book value.

The world then seemed to abandon all sense of valuation and sound risk management, but history ultimately vindicated the Warren Buffetts of the world.

The Market Can't Stay Irrational Forever

Normally few stocks go up in a bear market, but when prices become extremely detached from fundamentals, quality blue-chips can indeed rise during a historic market crash.

I'm not counting on anything I buy in the short term to go up in an inevitable market decline. Rather, I am counting on the time-tested principles of quality dividend-paying blue-chips, bought at reasonable to fair valuations, and then held for the long term, to help me achieve my goals of financial independence.

In the coming week, I'm planning on buying small amounts (about $500 in each) of

I buy one good deal or better blue-chip each day, as the "daily Phoenix portfolio buy" announced on the Dividend Kings' chat board three times each day.

Each buy is small, with the goal of gradually building up my cash/bond allocation (28% right now) by about $1000 to $1500 per month, while waiting for an inevitable market downturn.

Why these five Phoenix watchlist blue-chips? Because even in this overheated market, they fulfill the goals of prudent long-term income investors.

Fundamental Stats On These 5 High-Yield Blue-Chips

These five blue-chips are some of the highest quality dividend payers in the world, as seen by their average credit rating of A-, stable outlook.

S&P and other rating agencies base ratings on formulas that calculate historical default risk based on initial ratings.

And since bond defaults often result in bankruptcies, these are highly correlated with long-term bankruptcy risk for companies.

The probability of these five companies going to zero is about 2.5% each. The probability of all five of them going bust within the next 30 years, is about 1 in 102.4 million. Granted that's assuming a normal probability universe, which we don't live in.

But the point is that these five high-yield blue-chips meet all three criteria of prudent long-term income investing.

Think I'm being overly bullish about those probability-weighted estimates? Take a look at these companies' consensus return potentials through 2022.

That's estimated by taking the 2022 EPS consensus and assuming each company returns to its long-term, historical market-determined fair value multiple during periods of similar fundamentals and growth rates.

(Source: F.A.S.T. Graphs, FactSet Research) Now compare that to the S&P 500, and the horrible consensus return potential investors just buying the broader market, blind to dangerous valuations, might see in the short term.

In case you think that "this time is different" and that the market's earnings multiple will be permanently higher due to low-interest rates, and future debt-fueled stock buybacks, consider this.

Since 2009 we've had all the same conditions that are expected to continue in the future.

What was the market-determined fair value blended P/E during this time? 19? 20? 25?

Low-interest rates and copious buybacks didn't inflate the market-determined fair value of stocks above its long-term modern era historical norm, and likely won't do so in the future either.

Now compare the S&P 500 on the 3 goals of prudent long-term income investors.

The goal of prudent long-term investing is generating sufficient returns and income to achieve your personal goals while taking the least amount of risk possible.

Am I claiming that AbbVie, Scotiabank, Bank of Montreal, Philip Morris, and MDU Resources are going to keep rocketing higher as they have in the past few months?

Of course not, that was potentially a bear market low. The short-term gains you see after bear market lows are, in the words of Ben Carlson, "epic face-ripping rallies."

However, I've not focused on the short term.

My long-term goal is achieving financial independence with quality companies, run by competent and trustworthy management, that are paying me generous, safe, and steadily growing income in all economic and market conditions.

Dividend Sensei's Real Money Phoenix Portfolio Bucket

(Source: Morningstar) -28% cash/bond allocation not shown

Like my fellow Dividend King, Nick Ward, I divide my retirement portfolio into buckets. This is my Phoenix bucket, made up entirely of Dividend Kings Phoenix Portfolio daily buys that we make each day.

The official DK Phoenix portfolio is run using these risk-management guidelines, and my overall retirement portfolio is as well.

In a world of unprecedented pandemic, economic and earnings uncertainty, with risks to the market rising on a daily basis, I sleep very well at night knowing my hard-earned savings are entrusted to the skilled management at these financially strong companies.

Is a market downturn coming at some point? You better believe it.

Will I lose sleep when it arrives? No, because my long-term financial goals don't rely on luck, but uses sound and time-tested risk-management and long-term investing principles to create my own luck.

In 24 years of investing experience, I've learned what doesn't work, trying to get rich quickly.

In 6.5 years as an analyst, I've learned what does work, which is making, in the words of Charlie Munger, "consistently not stupid" decisions.

Let the market blow its hopium/TINA/FOMO/QE Infinity Bubble. Perhaps we'll even set a new record in terms of historical overvaluation.

At the end of the day, those whose savings are safety ensconced in a bunker SWAN portfolio have nothing to fear from the future, nor do we need to have crystal balls to meet our long-term goals.
