Moving averages are lowpass digital filters. The two types are Finite Impulse Response (FIR) and Infinite Impulse Response IIR). An SMA is a type of FIR filter, and and exponential MA is a type of IIR filter.
Lag is the common name for group delay. Group delay is the time delay of the various sinusoidal components of a signal, and is a function of frequency for each component. This immediately implies that the price time series is being modeled as a complex wave.
There are many ways to reduce group delay (lag) in digital filters, but I will point you to the work of John Ehlers. As always, a caveat. Anything from the world of physics, applied to finance, could be a misapplication of the physics.
Physics follows universal laws, meaning that, so far as we have been able to test them, they apply everywhere and at every time, past, present and future. What is the universal law of physics that is being applied to lag?

The negative derivative of phase with respect to frequency. Again, this implies that price is a complex wave with many different frequency component waves. It's just a model remember and thus the caveat.
Knowledge is king. I need the the lag so all the others who play with parameters get all the false signals. I have no problem waiting for middle swings.
