The SABMiller share price held up reasonably well this week despite the weaker-than-expected volume sales in the three months to end-June. Lager volumes were down 1% in that period against analysts' expectations of a 1% increase. A peculiar pricing battle with a leading Polish retail group was one of the stated reasons for the weakness in European sales. The situation has been resolved, so Polish sales should pick up in the current period.But the reported weakness in China volumes may have had a greater impact on overall group sales. Of course, the important thing about China is not the volumes sold so much as the price at which they're sold. Snow beer is being sold in China at not much more than the price of a bottle of water.To the extent that SABMiller can lift its pricing, the impact on group margins could be formidable, if it doesn't lose too many sales in the process.As usual, Latin America and Africa provided the contributions that ensure the group's blue-chip status. Can it be much longer before some investment bankers start talking about hiving off these really good bits in search of a more stellar rating?In the investment banking world, deconsolidation follows consolidation as sure as night follows day.Woolies share tradesstory_article_left1There were some major share trades by directors this week. The biggest was the R95-million transaction by Naspers' former finance director, Steve Pacak. But also substantial was the sale of 318155 Woolworths shares by Zyda Rylands, head of the group's food division. Rylands sold the shares to raise money to pay the tax on the profit she made from her allocation of shares from the Woolworths employee share ownership scheme. This week's share sale generated more than R31-million for Rylands, which suggests she's looking at a profit of nearly R100-million.Also on the Woolworths front, shareholders will be looking forward to the AGM for an opportunity to quiz the board on a plan to sell two of Australian retailer David Jones's sites.Lewis to face regulatorLewis's share price dropped almost 30% in the past 30 days and is back to the level it was at in November last year.The share price weakness is attributable to a possibly tougher regulatory environment. It's not so much that the regulations have been made any tougher, it's that the somewhat ineffectual National Credit Regulator has finally got around to looking at Lewis.The regulator has apparently been prodded by a number of parties who've brought Lewis's credit-granting practices to its attention. Lewis has dismissed the specific concerns raised by the regulator, saying they relate to only three stores. But walk into any of their stores and there's a good chance you'll be told membership of the Lewis Club is obligatory or that delivery charges are mandatory.JSE censures ArborThe JSE's censure of sponsor and designated adviser Arbor (formerly known as Arcay) is the first time it has issued a public censure and a fine. The investigation that preceded the decision to censure Arbor related to the period between August 2008 and June 2012.The JSE found that Arbor, or Arcay as it was known at the time, contravened large chunks of the listings requirements that relate to the responsibilities of sponsors. Of the R500000 fine levied, R400000 has been suspended for 24 months...
