Looked like an intentional overkill buy to flip the PSAR positive. Strangely the MM accepted the way-over-ask bid and gave it to him, perhaps with the knowledge that it would tweak the chart (although as of this moment all we have is an aberrant looking black candle). Also possible someone knew of the news and wanted to get something started, which of course it didn't. Whatever the case, it produced another meaningless candlestick movement that will get smoothed out by normal trading.
