Problem with amplifier?
This is because the bjt is in saturation at the high clips and in cutoff state at the low clips. You get this when the voltage levels (peak to peak) of your input signal is more than what your transistor can amplify. Lower the input signal until you see no clipping. Once the clipping is gone and you see that it does not amplify, you can try checking your circuit again, mainly the resistor values.
