This may be merely coincidence, but it seems unlikely.
The best performing sector on the benchmark US share index, the S&P 500, is currently energy. Of that sector, it is the oil services companies that are doing best – the ones who might have been hit heaviest had stringent new regulations hampered the way they were able to run rigs.
As I write, the sector as a whole is up 1.5 per cent, with services companies rallying 2.6 per cent. Halliburton is up 3 per cent, while rivals Cameron International and Baker Hughes have risen 4.5 per cent and 3.3 per cent respectively.
