1 of 7 to buy.....Penny Stocks to Buy: Patriot One Technologies (PTOTF) Running on a similar theme of security, Patriot One Technologies fully meets the definition that's traditionally applied to penny stocks. This name is a lesser-known OTC equity unit which is priced well below $1 -- trading at around 40 cents today. Still, I think PTOTF stock has potential because of its underlying relevance for the post-pandemic era. According to its site, Patriot One utilizes highly sophisticated artificial-intelligence (AI) systems to detect a wide variety of threats such as weapons and crowd disturbances, as well as autonomously monitor perimeter security and assess evolving community health risks. So, this company can provide alerts for things like terrorism. However, crowd disturbances are becoming an increasingly prevalent issue as well -- and something that PTOTF can address. According to an Association of Flight Attendants (AFA) spokesperson, air rage among unruly passengers is "the worst its ever been." Moreover, according to AFA President Sara Nelson, Flight attendants often will see the tip of the spear of whatever is happening politically or socially in our country. But trouble is not just brewing in the air. According to NBC News, restaurant patrons are becoming increasingly unruly as pandemic-related frustrations mount. These kinds of issues make this stock more and more cynically pertinent.
