Stocks that combine income and growth can sometimes be hard to find. But once you do find them, an effective strategy can be to simply buy the stock, sit back and relax, and let the investment work for you.

Here are two completely different stocks you can buy and hold forever.

Chevron

Putting Chevron (CVX 1.89%)on this list may raise a few eyebrows, but the company has demonstrated the effectiveness of its prudent approach to a volatile industry. Unlike other oil and gas companies that borrow too much money, pay dividends they can't afford, or overly spend, Chevron is one of the few energy companies with a solid balance sheet and an attractive dividend.

Chevron's strategy has also proved more successful than other majors like ExxonMobil (XOM -0.36%) in that Chevron's superior operational efficiency and lower spending has led to a healthier company that generates more shareholder value.

Another point to mention is Chevron's savvy negotiating skills. After Occidental Petroleum (OXY 0.21%), a much smaller company, outbid Chevron for Anadarko, a company roughly the same size as Occidental, Chevron simply walked away from the deal and pocketed a $1 billion breakup fee from Anadarko. Occidental shares were sent tumbling as outraged investors criticized Occidental for chasing assets at the expense of more debt, whereas Chevron's restraint looks to be a brilliant move given the current state of the oil and gas market.

It's also worth mentioning that Chevron's debt-to-capital and debt-to-equity ratios, two key financial metrics, are the lowest of the oil majors.

This indicates Chevron's dependence on cash flow and equity, more so than debt.

In late March, Chevron decided it would cut spending by 50% in the largest onshore U.S. oilfield, the Permian Basin, as well as total 2020 spending by 20%. Chevron also halted its $5 billion share buyback program. Such precautions help ensure that Chevron retains its financial strength while being able to afford its dividend, which currently yields 5.1% at the time of this writing.

Starbucks

Starbucks (SBUX -0.38%) investors have enjoyed a fivefold increase in dividends per share and the company's stock price over the past ten years.

Starbucks is now a household name around the world, especially in North America and China. However, the company recently announced a grim short-term outlook for the rest of 2020 in addition to the closing of 400 stores in the U.S. and Canada over the next 18 months.

Although this news looks bad, Starbucks has a track record of making the right adjustments. It's one of the few U.S. companies that has successfully tapped into the coveted Chinese market. As of Sept. 30, 2018, China represented around 20% of Starbucks' total store count. A year later, 600 additional stores were added in China for a total of 4,123 stores, over a quarter of Starbucks' total store count and nearly half the stores in the U.S. 

On Wednesday, Starbucks announced a major shift in business strategy as a direct response to the coronavirus pandemic. Going forward, Starbucks is focusing on increasing the convenience of grab and go ordering by leveraging its 19.4 million rewards members and mobile ordering. Even before the coronavirus pandemic, 80% of Starbucks' U.S. transactions were on-the-go, a trend that has only increased. 

So, while the headlines could lead you to believe that Starbucks is closing stores, it's really a shift from large low-volume stores to maximizing transactions through leaner solutions with fewer costs and overhead. In the works are pilot programs for Starbucks stores that exclusively offer curbside pickup, as well as the addition of stores specifically intended for urban customers on foot to pick up their coffees and go.

The company's decision to lean into the needs of customers during the pandemic pairs nicely with the growth of mobile ordering and paying. Although the short term will be challenging for Starbucks, the company has proven it has staying power over the long term. Its 2% dividend yield will pay investors to wait as the new strategy unfolds.

A motley duo

There's no denying that Chevron and Starbucks are a motley duo, but both companies have a track record of navigating uncertainty well. Chevron's prudence and restraint have benefited its balance sheet and given it a significant advantage over its competitors. Starbucks' ability to take a chance on emerging markets where others have failed or admit that its business model needs a revamp are signs that the company possesses a rare balance of ambition and humility.

For these reasons, it could be worth picking up a few shares of Chevron and Starbucks and holding them over the long term.
