JOHANNESBURG (Reuters) - South African technology investor Naspers posted a 90.5% jump in its half-year core headline earnings, driven by accelerated growth and improved profitability of its e-commerce businesses and contribution from China's Tencent.

Naspers said on Monday its core headline earnings per share (HEPS) for continuing operations rose to 865 U.S. cents in the six months ended Sept. 30, up from 454 U.S. cents.
