Companhia de Saneamento is up over the last week, after rallying aggressively off strong support in the $8.25 region. There is minor resistance between $10 and $10.60 (50% Fibonacci retracement), although primary resistance is not until $11.25 to $11.50 which marks the stop of a multi-month range.
Any pulls backs should find support above $8.75 (old downward trendline). If it drops below that, the former lows will likely be tested again. Aside from recent strength, another attractive feature of the stock is the 3.12% dividend yield.
