Synacor ( SYNC) is a provider of solutions for delivery of online content and services. This stock is trading up 6.4% at $11.95 in recent trading. Today's Volume: 599,000 Average Volume: 610,758 Volume % Change: 52% From a technical perspective, SYNC has started to flirt with a major breakout trade today, since the stock has briefly moved above some near-term overhead resistance at $11.89 with decent volume. At last check, SYNC has hit an intraday high of $12.50, but it has since pulled back to just under $12. Traders should continue to look for long-biased trades as long as SYNC is trending above $11.89 and today's high of $12.50 with strong upside volume flows. I would consider any upside volume day that's near or above 610,758 shares as bullish. If we continue to see SYNC trending above those levels, then this stock has a great chance of re-testing its all-time high of $13.60, and potentially trending even higher.
