Stocks With Insider Buying, Buybacks: ZMH

On the analyst front, Friedman, Billings, Ramsey's Randy Binner cut his target price but remained bullish on the stock with an implied 24% return from current prices. While dropping his price to $75 from $76 a share, Binner noted in a client report, "We continue to favor MetLife given its lower credit exposure relative to other life insurers."

We also like to see that TPG-Axon invests in Met shares. TPG-Axon is a leading global investment firm with more than $11 billion invested in public and private markets around the world. TPG-Axon also holds shares of Morgan Stanley MS and Union Pacific UNP.

Pzena Investment Management is another successful investment fund that owns Met shares. This $26 billion firm screens for stocks that are in the most-undervalued or deep-value portion of their universe based on normal earnings. The firm also likes Wal-Mart WMT and Citigroup C.

So with MetLife, we have a buyback, better-than-expected earnings, an analyst that likes the stock and two well-known investors invested. It may be time to do some additional homework on MetLife.

Next on the list is Zimmer ZMH. The Indiana-based knee and hip implant maker announced April 24 an additional $1.25 billion stock buyback program. The new plan adds to the roughly $477 million remaining capacity under an existing buyback program.

That same day, the orthopedic-device maker reported first-quarter results that were in line with Wall Street targets. On an adjusted basis, Zimmer earned $244.3 million, or $1.04 a share, on revenue of $1.06 billion. The company also reaffirmed expected year-over-year sales growth of 10% to 11% in 2008.
