Stock futures were slightly lower Tuesday morning ahead of the final session of the month and quarter.
The S&P 500 and Dow were on track to post gains of less than 1% for the month of June. The Nasdaq Composite outperformed amid a broad tech rally, with the index pacing toward a monthly advance of more than 4%.
During Monday’s session, the Dow’s more than 2.3% gain was powered in large part by Boeing (BA), which surged 14% during the regular session after the Federal Aviation Administration began its long-awaited test flights for the 737 Max. The aircraft manufacturer pared some gains in pre-market trading, dipping more than 2%.
