Nikkei up 0.1% as banks gain after Lehman results

(Updates to midday)

TOKYO, June 17 (Reuters) - Japan's Nikkei stock average edged up 0.1 percent on Tuesday, helped higher by bank shares after Lehman Brothers Holdings' LEH.N earnings came in as expected.

But the benchmark swung in and out of negative territory as investors took a breather after the previous day's rally, with recent gainers such as Honda Motor Co (7267.T) under pressure.

The Nikkei .N225 ended morning trade up 18.51 points at 14,372.88. It rose 2.7 percent on Monday to book its highest close in over a week.

The broader Topix climbed 0.5 percent to 1,408.23. (Reporting by Aiko Hayashi)
