Intel (NASDAQ: INTC) has been an industry laggard this year, rising just 5% as the Philadelphia Semiconductor Index rallied 20%. The bulls think Intel can bounce back with its market-leading positions in PC and data center chips, but several Wall Street analysts have become less optimistic about the chipmaker's prospects.Back in February, Canaccord Genuity analyst Matthew Ramsay downgraded Intel from Buy to Hold, declaring that "shares could remain range bound as margins stagnate" due to peaking PC margins and declining margins at its data center group.Intel CEO Brian Krzanich.
