Whether or not a higher YTM is positive depends on the specific circumstances. On the one hand, a higher YTM might indicate that a bargain opportunity is available since the bond in question is available for less than its par value. But the key question is whether or not this discount is justified by fundamentals such as the creditworthiness of the company issuing the bond, or the interest rates presented by alternative investments. As is often the case in investing, further due diligence would be required.
