Another high-yielding Canadian stock that's seeing excessive short attention is Shaw Communications ( SJR), a diversified communications carrier that provides cable television, Internet, phone and satellite services to 3 million subscribers spread across both Canada and the U.S. With a short interest ratio of 14.09, it would take nearly three full trading weeks for short sellers to unwind their positions in this firm. Shaw, one of the highest-yielding media stocks, is another strong contender for any dividend investor. The firm pays out income on a monthly basis and has already offered up a dividend hike this year, increasing its payout by 14% in March. Much of that growth can be attributed to investments that Shaw has made to build its infrastructure and increase the proportion of customers who pay for higher-margin services such as digital cable or bundled TV, Internet and phone service. For the future, the biggest catalyst for growth looks to be the mobile business, a new offering that management has long been in the process of bringing to market. With much of the infrastructure it needs in tow, including a wireless spectrum Shaw was able to acquire at a massive discount, and with solid balance sheet liquidity, expect shareholders to continue to cash in on dividend payouts for the foreseeable future.
