Many investors would prefer a simple way to invest that doesn't require them to look obsessively at the stock market every day. One alternative that many investors have turned to over the years involves picking the stocks known as the Dogs of the Dow. Despite some tough years recently, the Dogs of the Dow strategy is easy to use and has been outperforming the market so far in 2021. Let's take a closer look to find out why.

The basics of the Dogs of the Dow strategy If you're looking for an easy investing strategy, it's hard to get simpler than the Dogs of the Dow. The 10-stock portfolio is composed of the top-yielding dividend stocks in the Dow Jones Industrial Average as of the beginning of each year, and you'd purchase them with equal dollar amounts. You then hold the stocks for a full year. To use the strategy the following year, just look at the updated dividend yields and make substitutions as necessary.

Usually, the Dogs of the Dow method does well when value investing is in vogue, because Dogs of the Dow stocks tend to have high yields since their share prices have fallen relative to other Dow components. If those businesses rebound, then they can provide outperformance over the broader market. That's been true in six out of the past 10 years. Why are the Dogs doing well in 2021? The Dogs are getting some help from market trends this year. They include: A rebound in the energy sector. Chevron (NYSE: CVX) is up 24%, and while the oil and gas giant makes up only a small part of the Dow's overall weight, it has much more influence among the Dogs. A huge 42% rebound in drugstore retailer Walgreens Boots Alliance (NASDAQ: WBA) has definitely played a big role. Walgreens is the best performer in the whole Dow, and Dogs investors are getting an outsized portion of those returns, as its influence in the Dow is minimal because of its low stock price. Several hot stocks that flew high in 2020 have taken a break so far this year. For instance, Apple (NASDAQ: AAPL) and Nike (NYSE: NKE) are both down so far this year. Of course, 2021 is just over three months old, so it's too early for the Dogs to declare victory just yet. However, if you're looking for blue chip stocks that can stand the test of time, the 10 stocks that make up the 2021 Dogs of the Dow all have business strengths that makes them solid investment choices for dividend-hungry investors. 10 stocks we like better than ChevronWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
