Online brokerage house kabu.com Securities Co. said Tuesday it chalked up record profits and revenues in the fiscal first half, reflecting a recent surge in trade on the Tokyo stock market.

In its unconsolidated earnings report for the period to Sept. 30, kabu.com Securities booked a pretax profit of 1.1 billion yen, a 21-fold rise from a year earlier, while operating revenues rose 106.4 percent to 2.78 billion yen.

Both figures represent new highs on a six-month basis.
