 The coronavirus pandemic hit hard in the first half of 2020, prompting a series of extraordinary governmental measures to combat the disease: extreme social lockdowns, economic shutdowns, massive fiscal stimulus and support. The combination has created an unusual market circumstance, with economies in freefall, pummeled by the strongest recessionary pressures since the 1930s, while at the same time stock markets have rallied from the initial blow and given investors an 11-week bull run.David Kostin, head of US equity strategy for Goldman Sachs, notes the unusual situation and writes, Many of our client discussions have centered on the apparent disconnect between financial assets and the economy. Most institutional investors have been stunned by the juxtaposition of the sharpest GDP contraction on record with a 36 market rally, as have we.Thats the bad news. Kostin goes on to add the good news, The combination of incremental data improvement and extraordinary policy support has been sufficient to assure the forward-looking market that the earnings damage resulting from the virus will ultimately be short-lived.Looking at the light at the end of the tunnel, Goldmans stock analysts have tapped three equities which they see as likely to benefit and benefit strongly as economies return to a more normal level of activity. Weve used the TipRanks database to pull up the details, and find out what makes Goldmans picks so compelling.Post Holdings POSTWell start in the food industry, where Post Holdings holds a major portfolio of brands, including such breakfast staples as Raisin Bran and Shredded Wheat. At 6.1 billion in market cap, Post is a giant in its segment, with a secure niche based on quality products and strong branding. Nevertheless, the company has showed mixed results in recent quarters.The social lockdowns in place for much of 1H20 prompted a consumer shift to in-home cooking and dining, which benefited Posts sales. The company saw strong sales numbers in Q2, including 7.7 year-over-year growth to 1.494 billion in total revenue. Margins and profits contracted, however, and EPS came in at 65 cents, well below the 91-cent estimate.The mixed results come as individual consumer demand for Posts products is increasing. Those sales increases are overbalanced by reduced institutional demand. The restaurant, hospitality, and education sectors have all contracted, and demand for food stuffs there has not yet recovered.At the same time, Posts solid foundation in retail foods gives it strong prospects for the future. Goldman Sachs analyst Jason English covers this stock, and has upgraded POST shares from Hold to Buy. He writes, We expect the company to emerge as one of the scarce growth leaders in 2021 and believe its relative valuation is currently disconnected from this likelihood... POST has over 1.1 bn cash on its balance sheet... our FY20 sales estimates move higher for POST driven by the continued strong demand within its retail business specifically US cereal and refrigerated foods.English puts a 120 price target on POST shares, indicating his confidence in a robust 38 one-year upside potential. To watch Englishs track record, click hereThe Wall Street view of Post is in-line with Englishs. The stock has a Strong Buy analyst consensus, based on 6 recent Buys and just one Hold. Shares in this food company are selling for 86.14, and the average price target of 110.25 implies an upside of 28 for the coming 12 months.

Pinnacle is the Phoenix-based holding company owner of Arizona Public Service and Bright Canyon Energy, the major electric utilities in the state of Arizona. The companys asset portfolio totals some 18 billion, and Pinnacle boasts both an 8 billion market cap and a place on the SP; 500 index.Everyone needs electricity, so Pinnacle has had no lock of a customer base even during the coronavirus crisis. Even so, the economic turndown depressed demand, and the company saw sales slip in the first half. The Q1 results showed 661.9 million in revenues, down 10 yoy and missing the estimates by over 11. EPS, at 27 cents, beat the 16-cent forecast by 68.Despite lower earnings, company management is maintaining the dividend. Earlier this month, PNW declared its next payment, of 78.25 cents per share, to be paid out on September 1. The dividend has been stable at this level for four quarters now, and the annualized payment of 3.13 per share gives a yield of 4.26. This is more than double the average yield found among PNWs peer companies on the SP; 500.Analyst Insoo Kim has upgraded PNW shares for Goldman Sachs, bumping the stock from Hold to Buy. Kims 93 price target suggests a strong one-year upside of 31. To watch Kims track record, click hereSupporting this bullish outlook, Kim sees a clear path forward for PNW: The Rocky Mountain region including Arizona has recorded positive YoY electric demand, a stark contrast to most other regions in the US Exhibit 9. For Arizona, we believe favorable weather and state re-opening contributed to the increased usage, which should help PNWs prospects of achieving its reiterated 2020 EPS guidance range... Overall, Pinnacle West gets a Moderate Buy rating from the analyst consensus, based on 7 reviews including 5 Buys and 2 Holds. Meanwhile, shares are selling for 71.27, while the average price target of 85.40 suggests the stock has room for nearly 21 growth this year.

Ojea believes that BVN now has a clear path forward, writing, ...we have been cautious on LatAm precious miners given ongoing operational issues and declining volumes. However, specifically on Buenaventura, we believe that investors expectations on lower volumes have already been reset and that higher gold prices could be an important catalyst for the stock. Moreover, we expect a small improvement on costs due to the full roll out of the debottlenecking initiativeOjea has upgraded BVN making this stock Goldmans third important upgrade to a Buy rating, and set an 11.50 price target that implies a 27 upside potential.
