UN) are seeing their shares sold off like bad apples? PG shares recently plunged to $77.33 before recovering a bit to around $78. Yet, PG is still selling at a rich multiple. Shares have dropped 3.5% since the intraday high on my birthday, Aug. 21, (it feels so good to be 39 once again, but I digress). PG's PE ratio is still around 20. Below $78 a share the relative strength index (RSI) dips below 30, a technical oversold sign as well. Investors wonder why PG's pint-size rival, Colgate-Palmolive, is afforded a current PE ratio of over 24 while PG only trades at slightly more than a PE of 20. PG, with a market cap of over $215 billion offers investors a current dividend yield-to-price of over 3%. CL's market cap weighs in at around $54 billion and its current $1.36 annual dividend equates to a yield of only 2.34% when the price is at $58.22. Even when looking at the future (one-year) PE, CL sports almost a 19 and PG gets slightly less than 17. UN has a $109 billion market cap at a PE of 18.
