Strategy: Market Timing Effect On EMA

Common sense is that the market timing doesn’t matter much, or at least it should give very similar result if the overall strategy follows same idea. However, the difference is quite stunning.

The winning ratio (profit/loss stats) and day win ratio (strategy/benchmark) are close, beta is similar.

Measure CrossAbove Ema5>Ema20
Winning Ratio 0.395 0.387
Day Win Ratio 0.497 0.478
Beta 0.38 0.374

The difference lies on, MDD and Profit Factor.

Measure CrossAbove Ema5>Ema20
MDD 23% 40%
Profit Factor 3.47 1.7
Alpha 0.23 0.072

1 MDD is 23% vs 40%
With market timing, the max draw down is considerable lower.
2 Profit Factor is 3.47 vs 1.7
Profit/loss ratio is improved drastically when entering on timing.

Alpha
Alpha is improved when entering with crossabove signal. So can I say that the market timing signal actually generates alpha?
