Key themes:
Sell-side analysts and media attention are largely focused on demand for high-bandwidth memory (HBM) and DDR5 in AI data centers, the sustainability of rising memory prices, and the pace of inventory normalization. In addition, the recovery trajectory in smartphones and PCs, as well as guidance on capacity utilization and capital expenditure, are expected to be key drivers of sentiment.
Options Market Snapshot
Implied volatility (IV): Options expiring this week are pricing in IV as high as 124.55%, indicating extremely elevated expectations for movement.
Expected move: Options pricing implies a ~68% probability that the stock will move ±8.5% through expiration, suggesting a range of roughly $425.15 to $503.99 post-earnings.
Positioning: Total open interest in puts (384,293 contracts) exceeds calls (261,990 contracts), with a put/call OI ratio of 1.47, pointing to a bearish tilt in positioning.
Key strike: The $400 put holds the largest open interest, with 261,990 contracts outstanding. Despite being out-of-the-money relative to the current price near $460, this level may reflect either protective hedging demand or premium-selling strategies such as cash-secured puts.

Block Trades Signal Bearish Near-Term Bias, Bullish Long-Term View
Notably, two sizable bear put spread trades emerged ahead of earnings. The strategy involved buying nearly 5,000 contracts of $430 puts while simultaneously selling an equal number of $390 puts, effectively positioning for downside in the stock following results while offsetting premium costs.

However, longer-dated flows point in the opposite direction. One block trade purchased January-expiry $620 calls for approximately $20.82 million, while another targeted $750 calls with a notional value of about $14.04 million—highlighting aggressive upside expectations over a longer horizon.

Strategy Takeaways
With implied volatility already above 120%, options markets are pricing in significant event risk, making outright long straddle strategies relatively expensive.
For investors who expect realized volatility to fall short of the implied ~8% move, selling out-of-the-money options remains a common approach. For example, selling $500 calls or $430 puts—both outside the implied range—may offer a lower probability of being exercised.
To avoid the unlimited risk associated with naked options, traders may instead consider defined-risk structures such as bear call spreads or bull put spreads.
