** Shares in Puma PUMG.DE rise 20% in premarket indications after Anta Sports Products 2020.HK said on Tuesday it would buy a 29.06% stake in the sportswear firm from the Pinault family for 1.5 billion euros ($1.8 billion)
** Reuters was the first to report the deal earlier this month
** "The deal is odd in that Puma was apparently not involved, even though a competitor will become its largest shareholder," Morningstar analysts say
** Morningstar expects some controversy in Germany about an investment in Puma from a Chinese company, but a deal block seems unlikely since it is not a full takeover
** Shares in Puma have fallen 32% in the past 12 months
($1 = 0.8421 euros)
