My daughter Jordan and her boyfriend just returned from a weekend on the California coast.

They stopped at one of our favorite locations, the Santa Cruz beach boardwalk. We’ve gone there many times to take in the beautiful scenery, sample “cuisine” (like deep-fried Twinkies), and enjoy the rides.

And that means hitting the roller coaster.

I bring that up today because many investors feel that’s exactly where the market is taking them right now.

For many, looking at a chart of the S&P 500 of late gives them a very topsy-turvy feeling – to say the least.

This explains why I get the same question a lot these days. It goes like this: if there was one tech stock you’d never sell, what would it be?

For me, the answer is easy.

The one I have in mind is a great long-term play as well as a terrific place to park your cash – should you get stopped out of one of your favorite stocks amidst the volatility.

With $39 trillion in wealth up for grabs, this one beats the broad market by 65% over the long haul …

It was a legal award large enough to grab headlines – and the public’s attention.

Then again, an Oklahoma court recently ordered Johnson & Johnson (JNJ) to pay $572 million for contributing to America’s opioid crisis, one that causes more than 40,000 deaths a year.

JNJ says it will appeal the ruling. So, at this point, we can’t predict what the final amount will be.

But this much is clear – we need some type of technology that can provide accurate opioid patient monitoring, both in the hospital and the home.

And the good news for tech investors is there is, in fact, a terrific company that aims to solve this problem.

This is a stellar firm that has been at the forefront of non-invasive patient monitoring since 1989.

That’s a big part of the stock’s success. It often doubles the return of the S&P 500, something it’s already done all year.

And today, I’m going to run it through my five filters for scoring market-crushing gains that you can follow along with…
