 Down doesnt mean out. When a stock takes a tumble, investors sometimes jump the gun and assume that the name has reached the end of the line. Sure, a significant share price decline should sound the alarm bells, as it could indicate underlying problems with the business or insurmountable headwinds.However, theres another side to the story. These falls could reflect temporary challenges that can ultimately be overcome, with the lower prices presenting an opportunity to get in on the action before the stock takes back off on an upward trajectory.So, how are investors supposed to distinguish between the names poised to get back on their feet and those set to remain down in the dumps? Thats what the pros on Wall Street are here for.Using TipRanks database, we pinpointed two beaten-down stocks the analysts believe are gearing up for a rebound. Despite the hefty losses incurred so far in 2020, both tickers have scored enough praise from the Street to earn a Strong Buy consensus rating. Not to mention some serious upside potential is at play here.The Marcus Corporation MCSAs one of the leaders in the lodging and entertainment industries, The Marcus Corporation boasts several real estate assets that include hotels, resorts, theatres and restaurants. Although shares have plummeted 60 since the turn of the year, analysts believe that the company has taken steps in the right direction.B. Riley FBR analyst Eric Wold points out that during a quarter in which almost all of its theaters and the majority of its hotels were closed, MCS delivered an upset, with its Q2 2020 results surpassing expectations. Total revenues of 7.9 million blew the 3 million consensus estimate out of the water. This was driven by the reopening of its hotel network towards the end of the quarter. Additionally, thanks to its focus on limiting expenses, AEBITDA of -30 million bested the Streets -40.4 million call.Adding to the good news, Wold told clients, Even with fluctuations around the upcoming film slate, we continue to believe studios are more likely to adopt a staggered release scheduleeven with the disappointing after-hours news about Mulan going directly to Disney. With that in mind, management noted an expectation that the majority of the companys circuit by late Augustwhich would be in time for the planned opening of Tenet over the Labor Day holiday weekend.When it comes to predicting what attendance will look like, uncertainty regarding slate and capacity limitations cause Wold to take a more cautious approach. Although attendance could remain well below 2019 levels until 2021, the analyst thinks theres a high likelihood that it will rebound to within 5-10 of 2019 levels in 2022. Whats more, as only 3 of revenues for MCS are being used to cover rent expenses compared to 11-18 for its peers, Wold argues MCS gains an advantage by owning the majority of its real estate in the ramp toward profitability coming out of the COVID-19 shutdowns with a much lower break-even point compared to its peers on lower attendance levels.To sum it all up, the analyst commented, With multiple opportunities to extract value from that real estate, we believe it needs to be included in any valuation analysis and should, at a minimum, provide a valuation floor for MCS well above where the shares are trading.All of the above keeps Wold with the bulls. As a result, the analyst rates MCS a Buy rating along with a 27 price target. This target puts the upside potential at 115.
