Samsung's preferred discount hits 29% and Korea's top 1% traders take the cheaper leg

On the morning of the 18th, the stock most heavily bought by Mirae Asset Securities clients ranked in the top 1% for one-month returns was Samsung Electronics preferred shares, while Samsung Electronics common shares topped the same cohort's net-selling list ^[1][2][3]. Mirae attributes the switch to the preferreds' lower price and dividend appeal ^[4], which makes this less a call on semiconductors than a bet that one Samsung share class is mispriced against the other.

The arithmetic is the whole argument. At 11:56 a.m. the preferreds traded at 190,600 won, down 2.56% on the day, against 270,750 won for the common, down 1.37% ^[5][6]. Mirae put the gap at about 29.3% versus an 18% average over the past three years ^[7]; the quoted prices themselves imply 29.6% ^[13]. Either figure is roughly 11 percentage points wider than the three-year norm, or about 1.6 times it ^[14]. The convention here is straightforward: the wider the gap, the steeper the discount and, generally, the more attractive the preferreds look ^[8].

What gives the trade a cash-flow anchor rather than a mean-reversion story is the payout. Samsung's preferred shares are structured to receive slightly higher dividends per share than the common ^[10], so at these prices the same won of dividend buys 42% more yield on the preferred line ^[16]. Samsung has said it plans to return 50% of free cash flow and pay 9.8 trillion won in annual dividends under a three-year shareholder-return policy running from 2024 through this year ^[11]. On the second-quarter call the company said it would carry out that policy as promised and that the board and management were actively discussing implementation measures for this year, including a special dividend ^[12]. A special dividend is cited as a factor favouring the preferreds ^[9], and that is the mechanism: in a period of expanding payouts, the class with the higher per-share dividend and the lower price collects disproportionately.

Two caveats sit inside the same data. The cohort is defined by one month of returns ^[2], which selects for whoever has been positioned correctly recently, not for anyone with a durable view on share-class spreads. And on the day in question the top traders were buying the weaker leg: the preferreds fell 1.19 percentage points more than the common ^[15], which is how a 29% gap gets to be a 29% gap. Mirae itself says the data is simple information unrelated to the firm's views and does not guarantee returns ^[23].

The same list shows where the rest of the money went. Samsung Electro-Mechanics was the second-most bought stock at 1,491,000 won, down 4.30% ^[17], after Morgan Stanley moved its top pick to it from Samsung Electronics, keeping an Overweight rating and raising its target to 2.62 million won from 2.56 million, citing multilayer ceramic capacitor pricing, Ajinomoto Build-up Film substrate demand and AI data centre investment ^[18]. That target sits 75.7% above the traded price ^[19]. Eo Technics was third at 425,000 won, up 4.95% on an overnight US semiconductor rally ^[21], while SK hynix was the second-most sold at 1,682,000 won, up 1.82%, on profit-taking ^[20].

What to watch: whether Samsung's board converts "actively discussing" into a declared special dividend ^[12], because the spread only compresses if the payout lands. Watch also whether the gap narrows from the preferred side rising or the common side falling, and whether it stalls anywhere near the 18% three-year average ^[7] rather than settling at a new, wider normal.
