The launch of the tZERO token cryptocurrency has only been trading for a few days. This is a strong catalyst event, as speculation directly in crypto assets has produced huge % gains. Indirectly speculating through buying OSTK is a way into the crypto markets without as much risk.
The RSI is not oversold, MACD on the daily chart shows a strong green candle with room for further growth. Resistance was broken through and tested on Friday, so the first few trading sessions of this week will be available for day-trading gains. I'd watch for a pullback to re-test the resistance on Monday before taking a position.
