Sometimes it's not the easiest decision to bail on a particular investment. Especially when the holding is known for dividend increases, and is one of the holdings in the "Portfolio of the One Percent". I went ahead and sold my Rio Tinto, Plc (RIO) today. Reasons for the sale include the fact that I am up substantially on the holding, about 40% on average cost, and that the yield is historically low. Rio Tinto, although not exclusively a gold producer, does tend to track the price of gold somewhat closely. The company's major product is iron, however. You can see in the chart above, that the price of RIO has now caught up to the motion of the SPDR Gold Trust (GLD). The Due to previously weak results, the company is now sporting a trailing P/E of over 1900. Now, to their credit, Rio Tinto has had a pretty decent history of dividend increases, but for now I'd like to see if I can wait for something above 5%,which would would require a drop in price of at least 20% to achieve. Curious about where I'm moving the money to?I'm going short on the Biotech sector via the Direxion Daily S&P Biotech Bear 3x Shares (LABD). I'll have more to say about this trade shortly.
