The ASX200 has started the week higher and finished above the 6200 points level after plenty of momentum in world markets.

After a good US lead, the S&P/ASX200 benchmark index closed higher by 52.6 points, or 0.85 per cent, to 6229.4 on Monday.

The 6200 level has been a psychological barrier for traders for four months, and the index has rarely edged above it.

The All Ordinaries index finished better by 50.6 points, or 0.79 per cent, to 6435.6.

The Aussie dollar was buying 70.88 US cents at 1619 AEDT, higher from 70.77 US cents at the close of trade on Friday.
