SINA tests its 10-day moving average, levels to watch The shares have ticked at the underside of the 10-day moving average, last at $43.62 and still resistance. This could be a make or break moment for the stock technically. A breakout that holds above the 10-day would be price-bullish. Equally a failure at the 10-day could mean a continuation, and possibly acceleration, of the downtrend. In that event support would be at $41.14.
