Traders like this cross because the longer term SMAs crossing holds more weight and the breakout is more long term.

The most popular SMAs for the golden cross are the 50 and 200 SMAs. When the 50 crosses the 200, the 200 SMA, which had been a strong resistance level, becomes support and the uptrend into a bullish market is strong.
