Tech shares are out of favor, and economic growth in China is slowing. But shares of China-oriented network-equipment maker 3Com ( COMS) have looked relatively impressive, managing to tread water since I entered them in April of this year. Talk about defining success downward.I still like the shares, however, based on such quaint measures as revenue and earnings-per-share (EPS) growth. 3Com's cash and cash flow appear decent as well. When good old-fashioned valuation metrics start to matter again, I think COMS is a good bet to continue outperforming the indices. 3Com was left at the altar in March of this year by Bain Capital and its Chinese partner, Huawei Technologies. It was on its way to being bought out for around $5.30 per share. But when the Committee on Foreign Investment in the United States (CFIUS) voiced concerns about the deal, Bain and Huawei bailed. Trading for more than $3 at the beginning of March, and more than $4 at the beginning of this year, 3Com fell to below $2 on March 20 after the courtship officially ended.
