3 Stocks for Millennials to Buy and Hold There are stocks that lend well to day trading. And then there are those you just hang on to for a while.

There are stocks that lend well to day trading. And then there are those you just hang on to for a while.

In the case of younger investors such as Millennials, there are plenty of people who do both. For some, a taxable brokerage account serves as the "sandbox' for short-term trading while a tax-deferred account like an IRA contains investments that are in it for the long haul.

The most common long-term investment vehicles are mutual funds and exchange-traded funds which together produce broad exposure to several asset classes. While this is certainly a sound strategy, it doesn't mean that individual stocks can't also be part of your retirement mix.

Investors that take the time to understand a company's long-term growth narrative can become comfortable enough to buy the stock and let that story play out. Let's look at a few strong buy-and-hold candidates for investors with 25-plus years until retirement.

What are Sprouts Farmers Market's Growth Prospects?

The key to finding a good long-term holding is to identify a company that will benefit from secular shifts in consumer behavior. Health-minded grocery store operator Sprouts Farmers Market (NASDAQ: SFM) checks a lot of boxes.

The eating and shopping habits of the modern consumer are likely to have tremendous staying power. Especially coming out of a pandemic, people's interest in healthy foods and being in tune with what they eat could last for decades. That makes Sprouts' focus on health enthusiasts, which encompasses people from all generations, an attractive investment attribute.

The company competes in the $200 billion segments of the "at home' food market that is likely to become a bigger part of the broader $1.2 trillion grocery market over time. Its market share is minimal but that's a good thing because it means the runway for growth is very long. Over the next five years, Sprouts plans to double its footprint to over 400 stores by debuting in key markets like California, Texas, and Florida.

At the center of every Sprouts' market is a vast assortment of fruits and vegetables. Likewise, Sprouts stock would be a great core holding for the long-term portfolio.

It has less than a 3% market share in both the $100 billion sellers market and the $60 billion individuals market. As the business world continues to shift to efficient, technology-led financial solutions expect Square to be along for the long-term growth ride.
