Jim Cramer says the recent gains we're seeing in the markets matter. He says what also matters is how we get there. Right now it's through activism. We're in an activist and M&A phase with plenty more M&A to come so don't leave it yet. Consumer confidence is returning, with the index rising higher than expected in August. Cramer says Europe remains a worry, however. Europe is slipping back into a recession with industrial production stalling. As for sectors he likes, Cramer points to non-residential construction, banks and technology. The Dow hit a new high Tuesday and the S&P 500 climbed back above 2,000.
