The Australian share market has ended up posting solid gains, despite falls across the key mining and energy sectors.

The ASX 200 index closed 0.6% higher at 7,295 points, while the All Ordinaries gained 0.5% to 7,489.

Woolworths (ASX code WOW) was one of the market giants pushing the key indices higher, rising 2.4% to $39.54 after receiving an upgrade to buy from analysts at investment bank UBS.

"The sales outlook for Aust Food is positive due to more positive industry drivers and greater confidence that WOW can gain further market share," wrote analyst Shaun Cousins.

"Labour costs are rising but well progressed productivity initiatives and operating leverage support EBIT (profit) margin expansion."

Despite its share outlook being maintained at neutral by UBS, rival Coles also got a share price boost  today up 1.3% to $18.33.

The other major weight pulling the market up was a 2.4% rebound for biotech giant CSL to $284.44.

The gain today didn't make up for last week's much bigger slide, but was enough to help pull the ASX 200 higher, along with solid rises of 0.8 to 1.5% for the major banks.

The big miners and energy firms weighed on the market with moderate declines, such as 1.2% for Rio Tinto, 0.7% for BHP and 0.3% for Woodside.

However, many of the smaller players mining lithium or other materials needed for renewable energy took much bigger hits, with Lake Resources (-20%), Liontown Resources (-6%) and Chalice Mining (-5.6%) all down sharply.

But old tech fossil fuel miners also got walloped, with coal companies New Hope Corporation (-5.8%) and Whitehaven Coal (-2.9%) also on the nose today.
