After a rather choppy start to the year, the broader market has firmed up significantly, as fears over geopolitical tensions and slowing economic growth begin to ease. With sentiment shifting back to “risk-on,” selective small-cap stocks appear to offer exceptional upside opportunity from current levels, most notably those with strong growth forecasts, favorable valuations, and top Zacks Ranks.Two names in particular, The ONE Group Hospitality ((STKS) and Legacy Education Inc. ((LGCY), stand out as breakout ...
