 After a strong day trading, markets are hovering near record levels. The SP 500 is just 0.5 off its highest level ever. So as far as the stock markets can show, there is no economic recession. Things are looking up.Of course, we all know that the crises havent ended. The coronavirus is still out there. While daily data shows that the number of cases is starting to decline, there remains a strong public fear of the virus. Early efforts to control corona pushed us into an artificial recession a sort of economic medically induced coma that were now starting to climb out from. Yet, jobs are returning -- the July employment numbers beat the expectations -- so perhaps that stock market optimism is justified after all.Justified or not, in times like these a smart investor protects his portfolio. You dont have to go full-on prevent with the defensive plays, but finding some solid dividend stocks will shore up your portfolios income stream, making it more resilient against a variety of market pressures.With this in mind, we used the TipRanks database to pull up the stats on three stocks that analysts have tapped as buying propositions. These are stocks with a specific set of clear attributes, that frequently indicate a strong defensive profile: a high dividend yield over 8; and a considerable upside potential.Holly Energy Partners HEPWell start in the energy industry, where Holly Energy Partners provides transportation services pipelines, terminalling, and storage for crude oil and petroleum distillates. The company serves the oil industry in the Texas and Rockies regions, with operations in New Mexico-Texas-Oklahoma and Colorado-Utah. Holly has a market cap of 1.65 billion, and saw 533 million in 2019 revenues. Holly recently reported Q2 earnings, and the results beat the expectation. EPS came in at 48 cents per share, far better than the 29-cent forecast and equal to the Q1 earnings. Where many companies have seen severe dips in earnings during the corona half, Holly has managed to avoid that. Revenue for Q2 was down year-over-year and sequentially, coming in at 114.8 million.While somewhat mixed, the earnings were seen as generally positive, and HEP shares have gained 15 since the release.On an unequivocally positive note for investors, Holly has maintained its dividend. The company declared its divided last month, for 35 cents per common share, paid on August 13. Its important to note here that back in April the company slashed its dividend payment by 48. The cut was made to keep the dividend within the distributable cash flow, affordable for the company and kept up for shareholders. The July declaration marks the second quarter in a row at the lower rate, and shows that Holly has been able to keep the dividend reliable despite the crisis. Looking at numbers, HEPs dividend payment offers investors a yield of 8.9, almost 4.5x higher than the average yield among SP 500-listed companies.Raymond James analyst Justin Jenkins is sanguine about HEPs ability to operate profitably in the current environment. He writes, HEPs fee-based cash flow profile, backed by substantial MVCs has shielded the partnership from a measure of the macro impact. While continued headwinds to refining runs will drive some yy earnings degradation this year, we expect the partnerships earnings to mostly recover in 2021 as HEPs downstream-focused operational footprint provides relative insulation from declining U.S. oil gas production.In line with these comments, Jenkins rates the stock Outperform i.e. Buy, and his 18 target price implies a one-year upside potential of 16. To watch Jenkins track record, click hereOverall, Holly Energy Partners has a Moderate Buy rating from the analyst consensus, with 4 Buys and 3 Holds set in recent weeks. The stock is selling for 15.60, and at 17.80 the average price target suggests a 14.5 upside potential.

This is a strong return by any standard.Once again, it should be noted that this is a company which has recently cut back on the dividend payment. Dynex reduced its monthly common stock dividend from 15 cents per share to the current 13 cents starting with the June payment. The stated reason was to keep the dividend affordable for the company. Dynex appears to have been successful in that, as theyve now kept the 13-cent payment for three consecutive months.Christopher Nolan, 4-star analyst from Ladenburg, sees Dynex as a solid REIT with a strong portfolio and steady returns.
