Editor's note: Today, we continue our year-end series with another of the most popular ideas we shared in the Digest this year. This one is from Stansberry Research partner Dr. David "Doc" Eifrig...

In July, Doc shared with subscribers what he described as his "legacy work" – a combination of everything he has learned during his training and time as a doctor, a Wall Street trader, a writer and editor, and a business owner (he makes wine, for those who don't know).

In the July 19 and July 20 Digests, parts of which are republished and combined below, we shared what Doc described as a massive story overlooked in the financial media... and why an investment idea centered around it was the "best inflation hedge anywhere in the markets."

A Massive Story Almost No One Understands

By Corey McLaughlin, editor, Stansberry Digest

First things first, we need to share Doc's video with you...

This morning (July 19), our colleague and Stansberry Research partner Dr. David "Doc" Eifrig went live with his latest presentation...

It's a must-watch video for several reasons I (Corey McLaughlin) will briefly mention. The first is something Doc said early in the event – what he's talking about is as much an opportunity as it is a warning...

I know how ugly these last few months have been in the markets. I know you may be hurting. That you might be focused on just trying to weather out the storm.

But what I'm about to show you is actually a big part of the answer to what's going on – and how you're probably feeling – today.

From there, he got into the details of a story he says is bigger than anything else in the past 40 years, but something that few realize today even though it affects us all. Without giving too much away (we don't want to steal his thunder), Doc said...

What it does involve is a massive story that almost no one understands... Unfolding in the biggest, most important, and most bulletproof sector of our economy.

Among other things, Doc explained how what he's talking about is a sector that famously beats inflation... and why millions of Americans will pretty much have no choice but to patronize a particular set of businesses in the decade ahead.

If you don't already know Doc Eifrig...

He is a former Goldman Sachs trader and board-eligible eye surgeon who has been with our company since nearly the beginning.

And based on his experience, he said he can all but guarantee that the ideas he's talking about will be obvious to everyone in five years.

That's why he's sharing the message, so subscribers have the opportunity to take advantage of this trend now and position their wealth and health for a better future. As Doc said...

This research will be my legacy. I'm certain it could produce the biggest gains, by far, of my career. I don't think anything in the markets has one-tenth as much potential over the coming decade. Yet showing you that potential is only part of what I want to do.

This is the presentation I've been waiting my entire life to make. It's incredibly exciting for me – and daunting... If you're willing to listen, it can transform your life – in ways that go way, way beyond money.

Among the fascinating observations and advice Doc shared was this analysis of the markets that indicates stock-picking is a worthwhile pursuit...

In a study of more than 25,000 stocks, researchers found that just 1,000 of them – a mere 4% of the total – accounted for all of the $32 trillion in stock market gains over a 90-year period.

Just 30 of those – the top one-tenth of 1% – were responsible for $11 trillion. A third of the total gains over nearly a century.

And of those 30 stocks, five were from a single sector.

Of course, Doc then named this sector... and he explained why this is the perfect moment to invest in it...

The best inflation hedge in the markets...

These are some of the most defensive stocks on the planet, he said... But they can deliver massive returns with relatively low risk. And they outpace inflation because they have almost unlimited pricing power.

In fact, Doc said a study of 49 industry groups – dating back to 1926 – found that this sector was...

The single best hedge against inflation anywhere in the markets. Twice as good as gold. Nothing else came anywhere close.

And while beating inflation is one important factor for buying these stocks, it's far from the only reason to consider...

This is about a much bigger story, Doc says, and one that most people don't understand.

And keep in mind... this is from the same guy who warned last year about this year's massive rout in stocks and bonds because of inflation – another story most people didn't understand.

If nothing else...

It's worth tuning in to hear the details Doc shared about his fascinating background and life experience.

This is the first time I heard the full story of how Doc ended up writing for Stansberry Research after a career path that included getting his MBA... working on Wall Street... and then going to medical school.

You might be familiar with Doc's feelings about Wall Street... He left his job at Goldman Sachs because he got sick and tired of the conflicts of interest he saw up close while working in the financial world.

His father and brother were both doctors. Doc saw it as a noble profession, so he decided to pursue that instead. But he soon found similar disappointment in medicine, where he couldn't ignore the ills of the system that trained America's future doctors...

Like Wall Street, as I stepped further into this system that's supposed to help people... maybe you can guess what happened... I discovered medicine was every bit as corrupt and flawed as Wall Street.

Doc became a board-eligible eye surgeon, and he said he could have been a good doctor and even gotten rich. But as he explained in his video...

I knew I'd have to play ball with an incredibly broken and corrupt system. And I couldn't do it, no matter how much money I might be giving up.

Around that time, my dear friend [Stansberry Research founder] Porter Stansberry convinced me I could have 100 times more impact by talking directly to you – with NO censorship... no hospital board to report to... no toxic institution closing ranks around its bad actors.

The rest has been history and a benefit for hundreds of thousands of readers... In 2009, Doc started writing a research letter called Retirement Millionaire... and he also publishes the popular free daily letter, the Health & Wealth Bulletin.

We see the notes from folks consistently thanking Doc for his financial and health advice, as he is a rare independent expert in both fields.

Case in point... in his latest video, Doc shared a story about how he spotted a bump on Porter's neck and urged him to get it checked out. It turned out to be melanoma. They caught it early enough to save him.

As Doc explained, he brings the same approach to his work every day. I can attest...

Folks who know me appreciate that I won't hold back. I do the right thing whenever I can.

And he says along his whole journey – including now as an editor and writer – he always knew the moment that he's telling people about today was coming. And yet, folks today still are not talking about it... to their detriment.

That's why even in the middle of a crashing market... and ongoing war... Doc sat down to deliver the presentation he has been waiting his entire life for – for free. Click here to hear all the details now.

And Stansberry Alliance partners, you are more than welcome to watch the presentation from Doc... and you can also check out all of the brand-new research he is talking about here. It is included with your membership, of course, at no extra cost.

Editor's note: In this season of giving, Doc is reopening his original briefing on what he calls his No. 1 biggest discovery in 15 years at Stansberry Research (and more than four decades in the markets).

Using this research, Doc has already led his readers to many big double-digit gains since last July. To hear more directly from Doc and learn the full details about the sector he's talking about, click here now.
