 Back in September 2017, I picked seven beaten-down stocks to buy. I did so after reading a blog post from Ben Carlson, one of the best financial bloggers in the country. The problem with selecting beaten-down or penny stocks to buy is that they often come with a lot of baggage. Baggage thats not necessarily going to disappear overnight. When dumpster diving for beaten-down shares, you must be able to understand how far divorced fundamentals have become from investor expectations, Carlson wrote in 2017. While there were bargains galore in early 2009, late 2011 and even early 2016, if you want to find value in these markets, you have to go dumpster diving.InvestorPlace - Stock Market News, Stock Advice Trading TipsWell, of the seven stocks on my list, only one, Kroger NYSE:KR, is higher today than it was in September 2017. 7 Red-Hot Vaccine Stocks Racing to Develop a Coronavirus Cure The glutton for punishment that I am, Ive decided to go back to the dumpster to find 10 penny stocks to buy trading under 5 as I write this. Hopefully, Ill do a little better this time around. Penny Stocks to Buy: Banco BBVA Argentina BBARSource: Shutterstock Market Cap: 765.9 million Price-to-Book: 0.62Banco Bbva Argentina NYSE:BBAR, as its name suggests, is a financial services company based in Buenos Aires, Argentina. It has operated in Argentina since 1886. Its American Depositary Shares have been traded on the NYSE since 1993. It is the fourth-largest privately-owned bank in Argentina with 7.7 of the countrys total banking system loans on a consolidated basis. At the end of 2019, it had 454 billion Argentine pesos in total assets on its balance sheet. Banco Bilbao Vizcaya Argentaria NYSE:BBVA is a Spanish bank. It owns 66 of the Argentinian bank. Bank of New York Mellon NYSE:BNY is also a large shareholder with 18 of BBVAs stock.In 2019, it made 16 billion pesos on 88 billion pesos in revenue. That revenue is up significantly from 49 billion pesos in 2017. However, investing in Argentina is not for the faint of heart. The country is notoriously bad at defaulting on its debt, making investments extremely volatile. That said, BBAR is cheaper than it has been in the past five years. I would recommend the bank stock for aggressive investors only. Global Cord Blood Corp. COSource: Shutterstock Market Cap: 323.3 million Price-to-Book: 0.61After whats happened to Luckin Coffee NYSE:LK in 2020, most investors will probably want to steer clear of Chinese investments, except maybe Alibaba NYSE:BABA and a handful of other stocks. For those more adventurous, Global Cord Blood NYSE:CO holds three out of the seven licenses to operate cord blood banks in China. Two million babies are born each year in the three markets it operates: Beijing, Guangdong and Zhejiang. It has accumulated over 815,000 subscribers since its founding in 2003. Globally, there are 35 private cord blood banks in the U.S., another 104 in Europe and 54 in South America. Approximately four million private cord blood units are stored worldwide. Global Blood Corp. has 47 market share in China. The company charges a one-time processing fee of 9,800 Chinese Yuan and an annual storage fee of 860 Chinese Yuan for 18 years.

It adds up. 10 Stocks to Buy to Weather the Recession In the first nine months of 2020, the company had revenues of 132.4 million, 25.4 higher than a year earlier, along with operating income of 58.8 million, 39.9 higher than in the first nine months of fiscal 2019.

Guyana operates the Aurora gold mine in Guyana. The mine produces between 145,000 and 160,000 ounces per year. It has been in production since 2016. The acquisition creates a diversified precious metals producer that generates positive free cash flow. With Guyana Goldfields under its wing, it will have a strong balance sheet to make further acquisitions and move the Aurora mine from an open-pit operation to an underground mine with more than 14 years of production capacity. Newmark Group NMRKSource: Shutterstock Market Cap: 737.9 million Price-to-Book: 1.16Newmark NASDAQ:NMRK is a full-service commercial real estate advisory that provides services to both owners and tenants.

Sales were 2 lower than the consensus estimate while its GAAP profit was 3 cents per share, 70 lower than the consensus estimate. Since it announced earnings, its shares have basically gone sideways, which is a good sign if youve owned its shares for a long time. One thing dividend investors will notice is that the company cut its quarterly dividend by 90 from 10 cents to 1 cent starting with the June payment. With the dividend cut, it currently yields slightly less than 1. 7 Gun Stocks to Buy During the Coronavirus Pandemic Expect Newmark to face a tough commercial real estate market over the next few quarters. However, it has made several moves, including the dividend cut, to ensure it remains financially sound during the economic downturn caused by the novel coronavirus.

Two years later it completed its IPO. The company helps industries such as oil and gas keep their assets running safely.

Mistras core business involves the non-destructive testing NDT of assets, a market thats estimated to be 14 billion worldwide. It has an approximately 4.5 share of the global NDT market.In the near term, Covid-19 is causing delays in projects, especially in the oil and gas sector. As a result, it expects revenues to face declines in the second quarter, but that higher oil prices means the third and fourth quarters will likely see energy companies undertake testing projects theyve postponed due to the pandemic and lower prices.Down almost 70 year to date, Mistras is worth taking a closer look at.
