KEPCO Options Traders Turn Defensive as Earnings Approach

Korea Electric Power Corporation (KEP) heads into its August 14 earnings report with options markets flashing the sharpest defensive signal in months — a notable shift from the relaxed positioning described in last week's preview.

The standout change since the August 8 article is in options. The put/call ratio jumped to 0.66 on August 12, running well above its 20-day average of 0.52 — a gap of more than 3.6 standard deviations, the most elevated defensive reading in recent months. That is a sharp single-day move. The prior article noted the PCR at 0.51 with "little urgency"; the picture has changed materially in the final session before the print. Price action reinforces the caution: KEP has fallen 3.4% in one day and 3.9% over the past week, now trading at $11.88. The past two earnings prints saw the stock drop 3.4% on the day and 4.5% on the day respectively, with five-day losses extending to roughly 2% and 8.7%. That pattern gives options buyers a concrete reason to hedge.

The lending market, by contrast, remains broadly consistent with last week's read — though availability has tightened modestly from the extreme looseness reported earlier. Availability now runs at roughly 557%, meaning more than five shares are available for every one borrowed. That is still comfortably loose by any measure, well above even the year's tightest reading of 248% hit in early July. Cost to borrow at 0.51% is essentially flat and remains low. Short interest edged down 9.4% in the most recent session to roughly 2.1 million shares, continuing the retreat from the late-July peak. The lending market is not signalling any build-up of aggressive short conviction.

On the ownership side, the state dominates the register. The Korea Development Bank holds 32.9% and the South Korean government holds 18.2%, with neither changing position. The National Pension Fund trimmed its stake by just over 1.8 million shares in the most recent filing. BlackRock added 673,000 shares as of July 31, and Franklin Resources added 339,000. Analyst data is effectively absent — the consensus data is more than five years old and carries no weight here.

The August 14 print will test whether KEPCO can deliver results that break the pattern of post-earnings selling, at a moment when options markets have turned the most defensive they have been all quarter.
