The ma50 break/ out above is a very bullish signal with MACD/ RSI upwards momentum and not overbought yet. Lot of shorts in the stock too that will continue to cover.
Yes it was up last few days but so was any other stock that had a big squeeze from oversold levels (incl NFLX, SHLD, etc). Being up for days doesn't mean anything, it's T/A and other factors that matter.
Of course anything can happen in markets or if the general market (SPY/ SPX) take a dive then all charts don't work much but i believe this uptrend will continue for SINA.
SINA not just coming up from oversold levels but now more and more Anal-ysts upgrading it again and more positive news from China.
There's a small gap in 73 which could be closed this next week possibly.
