Jim Cramer explains why the Nasdaq failed to rally on Monday
1. Tech rally falters due to government export restrictions and Zuckerberg's criticism. 2. S&P 500 rose 0.16%, while Nasdaq fell 0.38% amidst market headwinds. 3. Cramer views government's semiconductor rule as 'short-sighted' and harmful. 4. Zuckerberg's comments on Apple may indicate deeper industry tensions. 5. Strong performance in semiconductors and pharmaceuticals shows selective buyer interest.
