Will mid-cap stocks see more decline? It is a high-probability scenario. But, in the current market, that could happen to small- and large-cap stocks as well. What matters to the street are valuations, quality of businesses, and individual managements. So, over the long term, it would pay to be bullish. Just remember three things: Be ready for some decline in the days to come over certain global issues; be more selective and cautious when picking stocks; and stagger out your buying.
