Joy Global's (JOY +1.3%) low takeover valuation may attract potential acquirers, as a buyer could offer a premium of 80% and still acquire it at the least expensive net income multiple on record for the industry, Bloomberg reports. JOY trades at ~8.2x 12-month trailing earnings, lower than 90% of similar construction and mining equipment makers. One possible suitor: Komatsu (OTCPK:KMTUY).
