Oracle (ORCL) is a buy at current levels, says Jacob Shonenshine of Barron's. He believes the company is poised to become a higher quality, high growth stock as it builds out its AI infrastructure. Jacob points to the stock's forward P/E ratio of 16-times as another signal of quality. As to why Oracle isn't being bought by investors, Jacob points to other issues keeping shares in a trough outside of its debt load and credit rating.
