HONG KONG, Oct 26 (Reuters) - Hong Kong shares could start lower on Friday, with Apple Inc's disappointing third quarter earnings possibly halting a 10-day winning streak on the Hang Seng Index.
On Thursday, the Hang Seng Index ended up 0.2 percent at 21,810.2 points, its highest close since early last August and equalling a 10-day winning streak recorded in February 2006. It last rose for 11 days in a row in November 1999.
It is up 1.2 percent so far this week, set for an eighth-straight weekly gain, which will equal a weekly winning streak posted in September and October 2007 and the longest weekly streak since the benchmark rose for 10 consecutive weeks in January to March 1991.
Up 14 percent from a Sept. 5 low and 18 percent on the year, the market now faces stiff chart resistance. The 14-day relative strength index (RSI) hovered at two-year highs, suggesting the market is overbought.
Elsewhere in Asia, Japan's Nikkei is up 0.2 percent, while South Korea's KOSPI is down 0.2 percent at 0100 GMT.
