What's in store today...

Nightclub owner Luminar (LMR) will step into the spotlight today, but the outlook is far from sparkling.

Analysts are predicting a fall in same outlet sales, having fallen in the previous three quarters, albeit at a slower rate thanks to a host of new initiatives brought in during the final quarter.

"If like-for-like trading stabilises during first quarter 2012, the share price could double, new equity financing could become an option, enabling expensive debt to be paid off and expansion to recommence. If like-for-like trading continues to fall, attention will return to covenant tests," said analyst Douglas Jack at Numis.

From nightclubs to international security, G4S (GFS) also gets a look-in on Tuesday. The group should hopefully publish positive figures from within a sector that has borne the brunt of cost cutting and bad press. Rival group Securitas suffered the wrath of broker downgrades, but G4S should benefit from its exposure to emerging markets.

Tony Shepard, analyst at Charles Stanley, commented: "During 2010, G4S has spent about £42 million on acquisitions of which the majority was in building a capability in the South American market especially in Brazil. Given the international nature of its business, the group remains well placed to grow.

"The share rating is not expensive being on prospective 2011 PE of 12 times and looks good value compared to other service providers which operate under long-term contracts. Our recommendation remains 'accumulate'."

On the numbers front, forecasts are for profits to exceed the £400 million mark - almost £100 million more than last year.

And flying the flag for the commodities market is Gem Diamonds (GEMD).

The diamond miner achieved an average diamond price of $3,291 per carat at its flagship Letseng mine in the fourth quarter, compared to $1,680 per carat in the previous quarter, reflecting the large diamonds which were recovered during the quarter.

However, a key issue for the diamond miner has been a lack of growth strategy, according to analyst Charles Kernot at Evo Securities.

"We believe that the market will be disappointed if Gem does not share its growth plans on Tuesday, but financing must also be addressed to ensure the plans look achievable," he added.
