Intel stock dropped 6% on Tuesday as investors reacted to the CEO's departure. Wall Street analysts say there's more uncertainty ahead for the chip maker.

Intel CEO Pat Gelsinger's removal has put an abrupt end to his role in the struggling chipmaker's turnaround efforts, leaving Wall Street with doubts whether his ambitious revival plan is headed for the chopping block.

When Pat Gelsinger came back to Intel, hopes ran high that he would restore one of Silicon Valley’s most famous brands to its former glory. Only two and a half years later, Gelsinger is gone, and the storied chipmaker is hemorrhaging cash and facing an uncertain future.
