TAIPEI, June 30 (Reuters) - Taiwan stocks were down slightly on Tuesday on uncertainty over global market stability amid the troubles in Greece.
The last trading session for the month, the quarter and for the half-year also kept investors cautious.

The financials subindex lost 1.0 percent, while the electronics subindex was mostly flat.
Among actively traded shares, large-cap TSMC was 0.4 percent higher, helping to offset pressure from selling in Cathay Financial, which was off 0.7 percent.
