Delta Air Lines -DAL- Daily - Showing relative weakness, sell

Lately DAL hasn't kept pace with the advance in the SPY, leaving me to wonder where all the table-pounding buyers have gone? I feel like a broken clock on DAL, constantly calling for a top in the chart, but once again the chart shows that something is wrong or that at the least there are sellers liquidating their positions as the price languishes relative to the S&P500.
