In this article, we will take a look at the best US stocks to buy under $20.
Every investor is looking to invest in the ‘best’ stock, but that word means something different to each of us. The real differentiation comes when that stock also trades at a low price. Low-priced equities are often viewed with skepticism. But in today’s market, low-priced doesn’t necessarily mean low-quality. In fact, data suggest that many cheap stocks consistently receive “buy” and “strong buy” ratings from top Wall Street analysts.
While investors pile into stocks tied to the crowded AI trade, Wells Fargo’s Scott Wren, who appeared on CNBC on November 20, emphasised “the power of diversification.” According to Wren, the market is moving into sectors, such as financials, industrials, and utilities, as he believes that this shift is a “cheaper way to get some exposure” to AI than directly investing in the tech sector. He adds that the diversification shouldn’t be too far away from the companies that are really growing. His comments suggest that attractive value can be found outside the market’s most popular themes.
With this diversification in mind, we have compiled a list of the best U.S. under $20 stocks to buy now. These stocks represent firms across various industries, including healthcare, defence, and communication services.
