Hello:

I understand that fm signals in the 150 MHz and higher range propagate
pretty much as line of sight.

But, is this also true for AM signals in this frequency range ?

This is generally true during hours of daylight. Medium wave signals
bounce off the ionosphere after dark thus allowing for long distance
reception.
