HONG KONG, Oct 5 (Reuters) - Hong Kong stocks rose slightly on Wednesday, outperforming regional markets, lifted by energy shares after an overnight surge in oil prices.

"We are a bit more conservative on the outlook for the Hong Kong market than the region due to our cautious view on the property sector," said Tai Hui, chief Asia markets strategist at JP Morgan Asset Management in Hong Kong.

On a price-to-book basis, the Hong Kong stock market trades at 1.2 times book, a shade below its 15-year average of 1.3 times. In comparison, the broader Asia-ex Japan market trades at 1.4 times book compared to a 15-year average of 1.7.
