\$r_e\$ is irrelevant to gain here with Re=1k.
- The base resistor values are wrong.

- Base to ground must be about 40x Re =40k
Base to ground must be about 40x Re =40k
- Rcb feedback must be much greater than 40k to bias collector near Vcc/2
Rcb feedback must be much greater than 40k to bias collector near Vcc/2
- Source impedance must be 50 ohms and if higher, then input impedance being reduced by NFB will attenuate source.

- With 0.5 mA = Ie you can expect up to 85% of open loop gain of 10=Rc/Re upto Rc/Re=100
With 0.5 mA = Ie you can expect up to 85% of open loop gain of 10=Rc/Re upto Rc/Re=100
- this % depends on input feedback attenuation and gains >100 are difficult to optimize , so don't try.

for Av=-100, Re=0 Rs= 50, Rcb=10k , Rc= 10k, Vcc=10V, gain increases with Ic and thus Vcc.
