The right hand side of C2 should connect directly to the transistor base, not power.I am trying to amplify the ac input signal but any input value results in 0V output, Can anyone what's wrong with my circuit? I don't want to use a voltage divider bias configuration.

Why is voltage divider bias a more stable bias than a collector feedback bias?
I have to make some assumptions about what you are really asking. There are 2 major ways to bias a bipolar junction transistor (BJT). The first is with a resistor in the emitter and a voltage divider to the base. Works great. The emitter resistor raises the input impedance and controls the gain. The second way is to connect a resistor between the collector and the base with the normal collector pull-up resistor to Vcc. Also works great. This method lowers the input impedance and controls the gain.

I suspect that if you actually knew how the one you don't know how it works, you would have not started this thread.Guys Thanks for all your replies. Really appreciated.
atferrari why I don't want to use voltage divider bias is because I want to test fixed bias configuration first.
Second I identified the mistake myself later and corrected the circuit and it finally worked with some different values.
Is there any book available that precisely focuses on circuit explanation? like what each component does etc
not just the basic theory.
Therefore a voltage divider biases the base plus an emitter resistor is added to 0V.
emitter resistor to 0V ??
