- Rule number one: there's always a premium on day one, and after day two it dries up — time is the premium.
- The main play this round is the big phone: iPhone 18 Pro Max, mainly 256GB and 512GB. The smaller models are down across the board.
- The bigger the storage, the easier it is to lose: 1TB / 2TB means big capital, thin margins. If you can't afford to lose, don't play.
+$3,000 on day one, gone on day two
This is Big V's first-hand post-mortem on iPhone 18 flipping at Sin Tat Plaza in Mong Kok. On launch day, one phone sold early enough could make about +$3,000; by day two the premium had largely evaporated. Big V calls it rule number one: there's always a premium on day one, and after day two it dries up — more supply, more people collecting their phones. A friend's real case: the same volume that made tens of thousands in profit yesterday made only a few thousand today.
Pro Max 256GB / 512GB is the main play
The big Pro Max held up relatively well, while the smaller models collapsed across the board — no premium, sometimes even at a loss. 256GB and 512GB have lower entry costs, relatively higher returns and the lowest risk. Why does the premium exist at all? Human nature: people racing to get the phone first and show it off — for some, a few thousand dollars is worth it. Lesson one for beginners: check prices at several shops before you go to Sin Tat — don't rely on a single quote.
Don't flip 1TB / 2TB: big capital, thin margins
High-capacity phones are expensive and harder to offload, so they're easier to lose money on; even with a small premium, the capital is bigger and the return worse. Cloud storage is everywhere too, so most people find 256GB / 512GB enough and won't chase huge storage when upgrading every year. Big V's hard risk rule: if you can't afford to lose, don't play — don't even set foot in the game; the higher the entry cost, the higher the risk.
Ignore foldable "futures" prices; the credit-card rebate maths
A foldable is expected around October, but quotes before anyone has the phone in hand — futures prices — are meaningless; Big V says treat them as noise. Buying tip: in launch season, max out credit-card welcome offers or rebates — for example, about 10% back on a $15,000 phone brings the real cost to roughly $13,500. Small buyers can fully use the rebates; for full-time flippers moving a hundred units at once it barely matters. Closing: don't touch the Pro (non-Max); focus on the Pro Max 256GB; the longer you wait, the more people collect their phones and the smaller the margin.
