DUBAI, July 24 (Reuters) - Gulf stock markets were soft in early trade on Sunday as weaker oil prices at the end of last week outweighed a few positive corporate earnings in Saudi Arabia.

Riyadh's stock index .TASI edged down 0.2 percent in the first hour. Saudi Kayan Petrochemical 2350.SE climbed 2.1 percent after it swung to a net profit in the second quarter of 91.02 million riyals ($24.3 million), ending a run of five straight quarterly losses and beating analysts' forecast for another loss.

Alinma Bank 1150.SE rose 0.7 percent after reporting a 12.1 percent year-on-year rise in second-quarter net profit to 409 million riyals; the average prediction was 395.3 million riyals. ID:nD5N17T00R

But falling stocks outnumbered gainers by about two to one, with Saudi Arabian Fertilizers Co 2020.SE (SAFCO) dropping 0.8 percent after it said quarterly profit halved to 299 million riyals, broadly in line with an average forecast by analysts for 290.5 million riyals. ID:nD5N19Q02B

Rabigh Refining and Petrochemical Co 2380.SE declined 2.1 percent after it reported a 79.6 percent slide in net profit to 103.2 million riyals, blaming the fall in profit on lower prices and tighter refinery margins.

Elsewhere in the Gulf, trading activity was subdued, with Dubai's index .DFMGI slipping 0.5 percent as Emaar Properties EMAR.DU fell 1.6 percent to 6.89 dirhams, retreating from major technical resistance on its October peak of 7.01 dirhams.

In Abu Dhabi, the index .ADI was weighed down by losses in mid- and large-cap shares, with Dana Gas DANA.AD the most heavily traded stock, declining 1.7 percent.
